Cool. I'll be amazed if it's a 2021 manufacture. Ciao

Sticker shimicker, this is the only way to tell the manufacturer date. Left column top to bottom 98,99,00,01,02. Columns to the right divided into separate divided blocks representing the months of the year. There's 2 dots one will be the month of 1999 and the other I'm not sure about, one may be the cast date and the painted date. Someone here smarter than me may be able to advise. So this one was definitely made in 1999 in either May or November, probably May. Lets see a casting image image of you 2021 labelled seat. Ciao

The aluminium knob is crimped around the top edge which is what provides the open stop. I carefully file off the crimp and then modify the plunger and body with a grub screw to create a new open stop which also makes the seals replaceable. Ciao

It won't last. The issue is the orings swell in fuel because they are plain nitrile. I reworked a few to use Viton seals. It's the only long term solution. Ciao

It's the ecu. There's a hot wire through fuse 1 to the ecu. 9.8/1 comp, not that high really. Ciao

It's laughably easy docc, even I can do it. When you think about the limitations of the std map your respect for them might wain. The std map has to cover all countries and condition, all the various emission regs for those countries, the different varieties of fuel and fuel quality and then in addition to that the FW factor. It's always one massive compromise. In the car world it's way more advanced than what we have on the old V11. My car you buy an access port for $600 and it comes with a 93/98 octane map so you pick up 15HP straight away. Then most tuners offer a deal for a few hundred dollars where they send you a base tune for your car and any mods you may or may not have and maybe 3 revisions. You hook up your access port which some people run on the dash all the time as it gives direct engine info in real time and go out and do 2 or 3 hard 3rd gear pulls on a quiet piece of road and log the parameters. Download the info and email it to your tuner and he'll look at the data and tailor the tune a little to your particular car and email it back to you. Load the new tune and repeat if you want even more refinement. 21st century custom tuning. Ciao

The later 4Valve head system is an improvement on the old style. As Pete has pointed out the lifter is smaller and lighter and has a one piece steel mini pushrod about 35mm long with ball ends that fits inside the lifter and protrudes from the top and engages the rocker arm. ( https://www.stein-dinse.biz/product_info.php?language=en&products_id=12039) The base circle on a Daytona engine is 21.5 mm and on a roller Griso engine is 29.6mm. A roller base circle can and is usually smaller than a flat tappet so I would assume the flat tappet Griso cam would have a base circle at least as large as the roller cam but packaging will come into it. Ciao

Just what I was thinking Pete. Ciao

The question is why the hell would you want to pay for this when you can do it for free via Guzzidiag. Not quite sure what the % and HP numbers they quote for the V11 Lemans is all about. Ciao

It's the breather hose from the frame backbone behind the steering head to the back of the engine crankcase at 1200 oclock. Ciao

OMG wrapped headers, leather saddlebag and bar end mirrors, what a turnoff. Ciao

Have you got one of these? I bought one 2 years ago, very good. https://www.ebay.com.au/itm/183730457624?chn=ps&norover=1&mkevt=1&mkrid=705-139619-5960-0&mkcid=2&itemid=183730457624&targetid=1278276341267&device=c&mktype=pla&googleloc=9071303&poi=&campaignid=10101784991&mkgroupid=131275693908&rlsatarget=pla-1278276341267&abcId=9300367&merchantid=116301090&gclid=Cj0KCQjw18WKBhCUARIsAFiW7JzGlavIc2B-pb2Lz8lIs23seejr9ACYiUarK8n0VDVTzG8QvO4d1JAaArzYEALw_wcB Ciao

Cars are a different topic and have different criteria. I don't understand why people apply car logic to motorcycles. Nothing worse than a "car guy" that takes up riding as his new hobby and then try's to translate "car world" stuff to the motorcycle world. Not saying this is the case here but "car guys" often just don't get it at all. Can take years to educate them and some just never get it. A work colleague years ago was building some sort of track car and mentioned he was fitting a water pressure gauge to it! What the hell for? So he could tell if he got a water leak while on the track! The logic escapes me. If you know how a water temp gauge works you'll know if you have a water leak. Ciao

Ducati make a desert scrambler with a carbon fibre sump guard but no protection whatsoever for the oil cooler.....smart. Ciao

At least carbon fibre has a few practice functions like reduced weight and higher strength so you don't get cracking of the front guard and side covers around the mounting holes. TPMS I can see a point to as a safety item with the bonus of a clock. Engine oil temp while I'm having a coffee! I'm more interested in the temperature of the coffee. Ciao

Precisely Chuck. There's more angst and hand wringing over what is displayed on oil pressure and oil temp indicators than just about anything else. So basically you add another/multiple failure points to indicate information that 99% of owners don't really understand anyway. Ciao

Ha, thats the least of it Pete. How about leather mini saddlebags to replace the side covers or a miniature brass old style wooden wheeled artillery piece bolted to the front of the front mudguard. Why? well because RE's old motto was "built like a gun". Everyone over there seems to think all this is great stuff. I'm just throwing up in my mouth. Oh btw, big believers in the piggy back air temp sensor modifier for the EFI tuning. Ciao

Yes I understand. I apply the opposite logic when I buy something, I'm a harsh marker and if it turns out to be a "less than optimal purchase decision" I'll cleanse my soul about it on the internet and let others know. In the car forum world I learned about confirmation bias when I bought a few "must have because the std item is shit" accessories and found when I actually took delivery of the car that the std items were quite acceptable. Not only did they overstate the usefulness of the accessory part they also trashed the OEM. Resold a few items as they just weren't necessary. The car world is quite rife with silliness, such as anything Billet aluminium is automatically better than the std plastic or steel item. Until the Billet item starts to degrade and fail of course and even then the purchasers will continue to delude themselves about it even when it's pointed out the std OEM item lasts for years and gives no problems. Visit the Royal Enfield forum and witness the stuff those guys bolt onto their bikes. Leather laced handlebar grip covers with 1 foot long dangly bits on the end and that's just the low end of the scale. Scary. Ciao

Well just to add another perspective (recalcitrant of course, because that's what I am ) I think they are very uncool and a waste of time. Just techno bling and another piece of redundant junk. As you pointed out you never really look at it anyway. Nice to know what the oil temp might be in a WCS but once you know that then it's redundant. Cool is actually only having fitted what's actually necessary, not ending up with the motorcycling equivalent of Graceland. Ciao

Hence the use of exhaust valves in MotoGP bike exhaust systems today. You can control the exhaust back pressure/density therefore the speed and timing to some extent of the reflective wave. Just another piece in the complex puzzle of exhaust tuning. Ciao

It's just a variable throttle stop. No mixture influence. Ciao

Its an Ancel BA301. Seems comprehensive and they do software updates apparently. If you select Motorcycle battery it lists a ton of different types by p/n but the Odyssey doesn't come up so I just selected Car battery and manually entered the type and CCA. I've had a few car batteries fail over the years the last one 18 months ago fortunately in the driveway. When this happens the modern electronics go mental and there isn't any warning like the old days when as the battery aged you got slower cranking etc which gave you some warning. Now they just work until they don't, so I decided to get one of these and monitor battery condition in my vehicles and change them before they drop their bundle. Voltage checks alone aren't an accurate indication of battery health. Ciao

I ended up buying this battery tester. Does pretty much everything including a load CCA test to give an idea of the battery health. Not a great image, sorry. Ciao
