Maybe I should start a thread about this, but most every bike I have tested with a thermometer at where the pipes come out of the head have a temperature differential. I have never checked the injector output on any bikes to see if they are the same, and I am pretty sure there is some variance. My idea was to use the fuel offset table in the ECU map (via Tunerpro) to increase or decrease the fuel across the board by a percent or two or however much is necessary to match the temperature of the exhaust at the header pipe. So essentially you would be matching the fuel output of the injectors by reading the temperature. Or if you measured the flow volume using a 9V battery hooked for a minute and calculated the percentage difference you could alter it by that difference in the offset fuel map.

No, no power loss in my case. Since the time I had a regulator go bad and high, cooking quite some acid out of a then rather new Hawker, I have installed a small two tone led inside the tach which roughly shows me the status of the charging circuit. Dark red below 12V, bright green above 14.5. Roughly. In-between it's ok. So when I saw the red light I knew I had to do something. First lights off, then head home. You may find the schematics for this little gimmick on Wayne Orwig's site. Recommended. Wayne Orwig's Guzzi Stuff or so

Mine were old and worn and delivered differently and replacing them made both exhaust headers look the same. This didn't hurt, at least. When I read through the posts above I can see only one conclusion: keep as much components straight and matched and level as possible. Are the injectors listed in the OEM parts/alternatives list? They are available for Lancias IIRC and should come sufficiently matched. Green ones should be ok. Alas, I can't remember what the specs were or where I found them. Maybe Guzziology ...

No, that happens just so. Me, too, had to go through this once. I could resolder mine. You'd need a solid iron, 100W is adequate. And it should not be your first attempt to solder something.

If it really bothers you, send your injectors to someone who can truly flow balance them. But I agree with Phil. It is not something I would loose sleep over. To add to the dynamics of it, because it is a 90 degree V twin with a shared airbox and exhaust there will be differences between the fueling of the two cylinders. And at different rpms the differences in fueling may shift due to the intake and exhaust timing and the relationship that timing has with fueling. The intake pulses from one cylinder can affect the intake pulses of the other cylinder and vice versa. The same thing for exhaust. But since the timing between the two cylinders firing is not even, one cylinder fires and a short time later the other cylinder fires then the time gap to the first cylinder firing is substantially longer than the previous time gap. These uneven intake and exhaust pulse can and will affect how the engine breathes. Meaning, as the volumetric efficiency of the two cylinders changes the fueling will change with it. Couple that with the difficulty of reading color as a indicator of lean or rich, I just can't see going down that road without more to go on. If you really are concerned, fit either O2 sensors or exhaust gas sensors to each header. Then see what you have. But really, the Guzzi system doesn't allow, as far as I know, individual tuning of the two sides. So, other than fudging the flow of the injectors what can you do? And fudging the flow of the injectors may back fire on you in ways you did not foresee. The most I can see doing, if you really feel compelled to do something, is have the injectors flow balanced. Replacing them you could easily end up in the same boat as chances are the new injectors aren't going to flow exactly the same amount any more than the existing injectors do. If it really was lean, lean to the point it was detonating or running poorly, I could see worrying about it. But as far as I can tell it runs fine and I have not heard of any issues with it. That is my two cents.

Good Morning All... So I’ve replaced battery and relays... This morning I had time to uncover my Stator cover to check connections.. I was careful doing so... and I found a broken connection. I certainly don’t think I caused this while removing the cap!!

But who says its lean, images can be misleading but it looks fine to me. The r/h may well be too rich. The only way to tell with any accuracy is to lambda probe each cylinder. Unless you're prepared to do that then its just going to be a drawn out proposition. Are we willing to wait for a few thousand miles to see the color of the ports to ascertain whether or not its corrected every time you make an adjustment or try something, because thats what it will take? I'll watch the rabbit get chased down the hole with interest. Ciao

I'm certainly not qualified to add anything to this, but a lean cyl would bug the crap out of me, and I would chase it to the best of my ability. which would include coming on this forum and ask

Unplugging the TPS and trying to rev the engine is a pointless test. Of course it will not rev and cough etc the same as not getting enough fuel because that's exactly whats happening. To test the TPS you need to use an Ohmmeter on it and look at the resistance shift verses the positional rotation. Ciao

I don't think there is a real definitive answer. Docc probably is close back when he "figured it ". Tank swell, your sending unit, being the biggest variables I see. Then there is the acceleration / braking factor...I recall braking could bring the light on and accelerating could turn it off - for awhile. Been awhile since i have seen "the light" since it appears my bulb is blown. I reckon thats not all thats blown with me

Love all the advice. I just put in a new fuel filter 6 weeks back. No reason than I was insulating the pump and figured 20 years on the same filter was enough. I'm going to check TPS in the next day or so. Looks like there is one on the right hand throttle body. I'll report back. Not sure where the crank angle sensor is have to look that up.

The Tach, Idiot lights and Ducati Energia Voltage regulator are all fed from the headlight relay so anytime the Tach is not working chances are the battery is going flat and you need to investigate straight away, first thing to do is see if the headlight is On. Of course if the headlight relay is open the Oil and Charging lights are not working either so you don't have any indication of a charge problem until the engine quits and you have a flat battery. The Voltage regulator must have 12 Volts to turn it On. My usual "get me home" fix is to wrap a wire around the black pin of the voltage regulator and stuff the other end in somewhere hot Some early bikes had the headlight fed through a normally closed contact of the start relay, it must be a 5 pin, This is an earlier version, Carl doesn't have an 03 Trace the Red/Black wire from the headlight relay to the regulator, see how pin 30 of the relay is fed from the start relay, Later versions are a little different, the headlight relay coil is fed from the start relay but the result is the same. You may find a better version of the diagram here but no perving at Carl's girlfriend Haha http://www.thisoldtractor.com/guzzi007/sportissimo.html

This years National Guzzi rally was held in Mapua, 30km from Nelson the major centre in the north of New Zealand's South Island. I live in Invercargill at the bottom of the South Island. My plan was to travel to Mapua, spend 2 nights there, another night at Franz Josef on the scenic West Coast and home the next day. The timing of the rally coincides with our Labour Day holiday, this commerates the introduction of the universal 40 hour working week introduced in 1840. This holiday is observed on the 3rd Monday of October. I took 2 days off work to make this trip, the preceding Friday and the following Tuesday. Day 1 I set off bright and early on Friday October 19th at 6am. The day was clear with an unseasonal frost of about 3 deg C on the ground. I was planning to travel 1000k/620 miles so the plan was to stop every 50 miles or so for a rest/photo stop. My first stop saw me catching the sunrise on the back road. http://i227.photobucket.com/albums/dd216/O...t07003-Copy.jpg After another stop on now sunny but breezy day I found myself in Dunedin affectionately known as the Edinburgh of the south. New Zealand's first city by population growth in 1865. It is now NZ's fifth largest city widely recognised as a University city whose students are known far and wide as "scarfies". The central streets of Dunedin are shaped in an octagon and who else but Robbie Burns would have a statue in his memory in the centre. http://i227.photobucket.com/albums/dd216/O...t07004-Copy.jpg The trip up the east coast is nothing startling at all, another photo stop was at the 45th parallel, halfway between nowhere. http ://i227.photobucket.com/albums/dd216/O...07005-Copy.jpg The day continued sunny but now windy which kept the temperatures low around 12-14deg C at max. A couple of gas stops later I found myself turning off SH 1 in the direction of Springs Junction over one of our mountain passes, the Lewis Pass, at its highest point 907m ASL. Travelling along a long undulating straight piece of road, along way ahead in the distance I see some flashing lights, instinctively look down and I am doing 85 mph. As our speed limit is only 100kph (62mph) and an instant loss of licence at 40kph over the limit I was fearing the worst here. I slowed down to the speed limit and as I approached the parked patrol car I continued to slow waiting for the door to open and the inevitable invitation to stop be extended my way. But nothing happened, what I couldn't see was the little boy racer car parked in front while he received his ticket. I continued on my way at a somewhat slower pace. A nice road which winds it way through some magnificent sub alpine scenery. http://i227.photobucket.com/albums/dd216/O...t07009-Copy.jpg The going gets a little tighter once it enters the bush proper. Eventually I arrive at Springs Junction my last fuel stop of the day. The time is 4.30pm and only 210k/130m I am feeling good. I head off north to Nelson now on my last leg knowing I should be at Mapua in about the 13 hours I had allowed myself for the journey. At a rest break in Murchison I run into another 2 travellers who are heading to Mapua as well. Both from Auckland one on a V11 LeMans the other on an MV Augusta, they had had a quick look around the top half of the South Island. I head off leaving them to it, enjoying the winding well surfaced roads on offer. This leg of the journey was the best as the wind had died down now and even though it was the evening it was the warmest part of the whole day. About 50km from my destination approaching a little place called Belgrove the back of the bike starts wobbling frantically. I stop thinking I have a flat rear but no that's not it, my left rear wheel bearing is toast. I turn back to the hotel and stop. Inside, I ask for the local phone book, find the number of an old friend I haven't seen for the best part of 18 years, fish out my mobile which my wife insists I carry for such emergencies to ring, when of the patrons ask what network I am on. I tell them and they say sorry no service there. All is not lost though the bar owner hands me her phone to ring. Eventually I get picked up bike and all and taken to Nelson where we remove the rear wheel and after a lot of catching up I get some well deserved sleep. Day 2 A nice sunny day dawns on Nelson, we remove both wheel bearings and replace them, refit the wheel and about midday I am off to the rally site at Mapua. The Saturday ride for the rally entailed heading over the hill to Takaka and there was to be lunch at a salmon farm. You catch 'em and they cook 'em. But as I have a workmate living at Takaka if he was working I was going fishing but as he was on days off I was going to catch up with him. By the time I arrived at Mapua nearly everyone had been gone for more than 2 hours. I enrolled and headed off to Takaka. I fuelled up at Motueka and headed into threatening skies and the unknown. I had never been to Takaka before which involves the Takaka hill. By the time I started up the hill it was raining, not heavy, just enough to dampen my enthusiasm. By the time I reached the summit the rain had stopped and I continued on damp roads in sunshine. Encountering rain wasn't surprising as it had rained for 18 of the 20 days of October in Takaka. http://i227.photobucket.com/albums/dd216/O...t07011-Copy.jpg http://i227.photobucket.com/albums/dd216/O...t07012-Copy.jpg Once down the other side and through Takaka North the road was made for motorcycles, nice and flowing. At Takaka I stopped off and had a cup of tea and visited our workplace there and headed off back to Mapua about 5.00pm. I missed some more afternoon rain showers and had a nice ride back in evening sunshine. The hill itself I didn't enjoy, I found the corners too tight for my liking, alot of first gear stuff. As someone said later on in the evening about the road, they ran out of 25kmh warning signs so they put up a 15kmh one instead. Once back in Mapua it was time for the rally dinner. About 120 people attended the dinner and thoroughly enjoyed the live music that followed. Day 3 I was up in time to see the WRC final at the dinner venue. South Africa had the Poms on the ropes by half time and that was good enough for me. I left and wandered round the camp site taking photos of some of the bikes that were there. There was street racing on at Greymouth 290k/180miles from Mapua and my intention was to watch some of these. I was late getting away, the trip to Greymouth meant I covered some of the roads I travelled over two days earlier and they were much more enjoyable this time around. The day was cloudy and breezy but heading towards the Coast I encountered patches of rain but nothing serious. This meant the ride down the Buller Gorge which is rated by some as one of the best motorcycle roads around was spoiled by the intermittent rain and wet road. Once out of the Gorge all the mountains were shrouded in mist and this continued all the way down the Coast to Franz Josef. I stopped for fuel and fish and chips at Westport and arrived in Greymouth in time to watch the last 2 races. From what I saw we should see some really exciting races at Wyndham during the Burt Munro Challenge weekend later on this month. I got some fuel at a little place on the Coast called Ross. This was a step back in time, no fancy computer inside, the shop assistant had to go outside and read the pump to see how much I had purchased. I arrived at Franz Josef in time for a couple of free bowls of vege soup the hostelers put on every evening. Day 4 The day was an absolute blinder no clouds in the sky at all. The road was dry and I was off, 575km/375miles to get home. http ://i227.photobucket.com/albums/dd216/O...07014-Copy.jpg Nice flowing roads, just the occasional tighter sections things were looking good. After a stop at Fox Glacier for a photo stop there was even a decent straight for a triple digit blast. At my first rest stop I looked down at my front tyre and this is what I saw. http ://i227.photobucket.com/albums/dd216/O...07016-Copy.jpg Here I was a million miles from anywhere, a public holiday and just me and my tyre. I set off at the sedate speed of 80k/50mph getting passed by all and sundry. After a couple of stops it didn't seem to be getting any worse, I continued home. A fuel stop at Haast meant I had only 433k/270miles to go. I carried on with another gas stop at Alexandra and arrived home thankfully without any other incidents. In total nearly 1400miles/2250km in 4 days at an average fuel consumption of 39.48 imp mpg/7.19l per 100km. Apart from the wheel bearing and the front tyre and camera troubles the trip was really good. Seeing parts of the country I had not seen before and catching up with people I hadn't seen for two years. My camera or more correctly memory card failed me miserably. I had intentions of taking some video clips of the rally so I borrowed my daughters 1 GB card. I unfortunately came home with only 14 images saved on the defective memory card instead of the nearer 50 I took. The following day Tuesday, I had a nice day at home then sadly back to work as usual on Wednesday. Next years rally will be in the North Island, I can't wait. Rob

good trip report 02v11. i hope to oneday get over there for a ride around. ps. your front tire is well shagged.
