Is there a source that talks about the different Guzzi cylinder heads? Looking at a 1000cc (square head) bike with broken fins, just wondering what options are for a replacement head if I move forward.

Already have one, they are special motorcycles, these are racing motorcycle with lights and mirrors, not production bikes made to go fast. First gear is so tall, but the rest of them are so close. Still ride mine from time to time, but with values going up, just one more thing in the back of my mind during the ride. I did spend a day at Barber on mine, I did the Class motorcycle school the first year Barber opened. The bike was more at home on the track than I was, but still a fun day, even getting passed by Reg while he was two up. I do miss my Greenie...

Love the Little Feat quotes, one of my favorite bands! Now, if we could work in lyrics from a Fat Man in the Bathtub.. Hay Mama, hey, let me check your oil alright?

I think we missed our Quota....

Home! Had a lot of fun! Good to meet everyone, and if you are caravaning down the Interstate pulling trailers, Adam is a heck of a Wing Man!

Not far out of the way, I can drop it, I come down 23, seems a short detour down 123 to get there, when is the package showing up? Driving down Wed and then back the following Monday.

Where in GA? I'll be in Monroe next week so I can bring it down to you, I come from NC through Dillard, Commerce, Athens, then Monroe, so if that is not too far, I would be happy to help.

I'm an hour away, see you in the morning, trailer was slick this morning...

I got a little last minute maintenance done today, I will load up tomorrow and stay in Lenoir City tomorrow night and be there bright and early Friday.

They told me no breakfast at this time, not sure about coffee, I might bring my own (coffee), but a group breakfast at a sit down place sounds good.

If I had a bigger trailer I would bring my RC30, but I'll stick with the Italian theme (this year).

Lucas, the Prince of Darkness? Are you sure it is not the wiring smoke issue?

I'm going to have to order a Bosch off the interweb, might get a blue Bosch coil at the same time just to have, but... SUCCESS!!!! Chased my tail for a $10 part that I can't test... I just bought what they had on hand, made in Taiwan, maybe better than Mexico or China, not sure, but after putting the right end on it, she fired up and ran great. Let her run on the lift for a while, sounded good, I think the idle has picked up a little, after about 10 minutes of that, out on the road. Last time it was the second climb up the hill where she started to miss, this time she did fine, even rode down to a buddy's house and then back, maybe 5 miles, but that is 4 more than last time. I will keep a spare condenser with the bike going forward and a small slotted screwdriver and an 8mm wrench, which may be in the tool bag. Now, about 2 more hours for the Boston Butt and all will be right with the world, at least for me!!! Thanks for the help!

This issue is definitely in the ignition system, I put a spark tester on it as well as my chainsaw tach, the spark tester showed spark get inconsistent as the RPM picked up on the left cylinder as it ran on the right, the bike would not run on the left cylinder other than start and idle, but even then you could see some inconstancy in the spark, the chainsaw tach showed pretty much the same thing, wild fluctuations in RPM while the bike was missing but staying about the same rpm. I even cleaned the old cap and put it on and it acted just the same. I think parts store run for a condenser to see if that helps.

I found my old coil and measured it, only 1.5 ohm between positive and negative, so no good, found a new coil for an agricultural project that measured correct, so I installed it. I also put the spring and button from the old cap in the new cap and that got resistance down to 10 ohms and much more consistent. Put it all back together, fired right up like it always does and she ran great for about 10 minutes... Then back to pop and stumble, so I checked plug wires while hot, they dropped a touch to 4.2k ohms, still not bad, checked the coil to points, 0 resistance, no issue there, coil to distributor cap, about the same, so no issue there. Only thing I can think of now is the condenser/capacitor for the points, I may run to the parts store and pick one up for a 76 VW Bug and put the right connector on it and see if that helps, I am to the point of throwing parts at it...

Now I am really confused... The coil is 2.8 to 3 ohm across the + and - terminals, about 8.5k from either + or - to the cable out to the distributor. The resistance of each plug wire with cap is about 4.5k ohms, and they have 5k ohms printed on the caps. To me that is all close enough to what it should be that I think it is OK, although once in use and hot those may change and cause my issue. Now where I am struggling, on the distributor cap, both wires out to spark plugs are no resistance from out to in on the cap itself, but from the coil (center hole) to the spring loaded button I am getting resistance from 30 ohms to 50+ ohms, and it bounces around, even if I try to hold it in the same position. If I pull the spring and button and out and just check just the cap, there is no resistance, so all the resistance is in the spring and button. So I took my old cap and looked at it, old and dirty, but no resistance to the plug wires, but 1.2k ohms in the center hole to the spring and button. I pull the spring and button out and it is the same, so it seems resistance is in the cap itself, and it is very consistent when pushing the button in on the spring, or it is too low to be picked up based on the resistance in the cap. I will keep playing with it, I might swap spring and buttons and see what that does.

The coil is from MG Cycles, I am betting a 3 ohm, going to check it. I will pull the plug wires and caps and check them first, I am going to smoke a 8 lbs butt today, so I will have some time to work. The jumpy tach makes me think coil, also, when something runs well for about 10 minutes then starts to get flaky I normally think electrical, it heats up and fails. Several local parts places have coils that will work, so if I need to, I will go get one, might order a Bosch Blue for the future, or just not leave the d@mn key on so long while chasing gremlins...

I'm going to pull the seat and tank tomorrow, check coil, wires, plug ends, and plugs, got to be something in there, fuel would turn my plugs black.

It ran good for about 2-3 miles, then the same thing, had to run her about 4k-5k rpm to get home (I live on top of a hill), more than I wanted to run her during break in. Running better at higher rpm seems odd. I really think it is electrical, wonder if I fried my coil or condenser while I was working on my headlight switch. The only wire I have not replaced on the bike is the wire between the coil and points, not sure if this is a resistor wire or a normal wire, if normal, I can build it myself, if resistor, I might be able to get the wire and build it. The tach gets jumpy when it starts to miss, which again I think points to my ignition system. Need to get this solved soon, or she will not make it next week.

Single points system, I'll give her a test ride this morning and see if it is fixed.

Looking for a little help. I took the Ambassador out on Thursday and made it about a mile from the house and she started sputtering and spitting and lost most power, I quickly turned around and barely made it home. The main thing I worked on since the first ride and this one is the headlight switch, so I had the key on quite a bit. Anyway, I pulled the plugs and they both looked fine (slight brown tint), I pulled both float bowls and they were full, maybe a little trash, but looked at both filters and not much in them (the tank valves have filters too). I pulled jets and they were all clean. I rechecked points gap and timing, still ran bad. I pulled the points out and had a little black on the edge, wondering if I burned them slightly with the key on. Would that have that big of an impact? I cleaned the points/coil connections, sanded the points, re-gapped them, re-timed and started it and it sounds a lot better, I will take it for a ride in the morning, but a little nervous about it.

Are people showing up on Thursday? I will be on LC on Thursday, so I can run over in the afternoon.

My penance for being spineless...

I'm a couple hours north of Tellico Planes, just some rain and light wind, more rain coming but I think it will be ok, supposed to blow through by tomorrow evening. The nice part is the cooler weather, high 70's Thursday and Friday, time to do some test rides.

Alfa damaged the reputation of the Busso V6 with a bad head gasket, great design, individual aluminum caps on each cylinder liner to seal compression, then cheap material for oil and coolant sealing, better material and it might have been a different story. What they did get right was maintenance, you can pull the cam shaft out without disturbing the timing belt to adjust the intake valves (bucket over shim), exhaust side was short pushrods with a rocker arm with screw and nut adjusters. The car (GTV6) was too expensive to build and the rumor is that lead to the sale to Fiat. Now for Italian vs German engineering, Alfa has 4 seals on the front of the engine, crank, 2x cam, distributor drive, the crank seal is one size, the other three are the same. Wife's 944, 4 seals, crank is one size, the other three are all different by 1mm, either ID or OD, drives me crazy.
