Fuel injectors

That is the first thing I would do. Someone else has been buggerising around with it, and you have no way of knowing if it all makes sense. The best thing to do is go back to the base-line, and make your own decisions from there.

Also, please read what @pete roper recently wrote on the subject. I reckon it might be relevant for you too.

 

PS: I didn't see you mention the motor position sensor. I have very reliable advise that it only a matter of time before they fail.

My V11 Le Mans runs very badly between 2 and 3,000 r.p.m, and that sensor is what I'll be looking at next. No idea if that is logical, but I'm pretty sure the issue has nothing to do with the fuelling, but rather with the spark management somehow.

Pretty sure that I will go to a base setting with just the ecu and pipes, but I know the injector was not functioning as it should because starting the bike and getting it to clear out and run caused the exhaust to glow red. We tapped the injector and it settled right in and the pipes were both at 345 degrees and it idled really well. I can't speak for the past of the bike but and they didn't put many miles on it when the rode it towards the end of their ownership and it sat, the gas was not good in the tank and he rode it that way. I pulled the tank and dumped it and put a new filter in the tank. Seems that all perimeters including TPS, throttle body balancing, valves, fuel, plugs, new gas, new air cleaner are done correctly. I was going to disconnect the PC and see if the 2-3 grand stumble went away. My friend that did the work suggested that I run the fuel injection cleaner first for the injector and then richen up the lower part of the PC and see if that did anything. If not I will then pull the PC and go back to stock....

Why would you want to use rubbish like these when Guzzidiag is available for free is beyond me. Even if I already own one it would sit in the draw unused these days.

It was a way to put it on and go. I live a long way away from others and getting into a whole new computer program and set my bike up sounds great but this was the path of least resistance. Sometimes you get lucky and shit works... and I have had great success with them before. If it doesn't work, then I will give Guzzidiag a shot...so there you go we shall see. My next step is to put it back to stock and see if that will change anything.

Unfortunately , getting this bike in PERFECT condition is demanding and you have to follow every step to perfection to achieve any type of happyness .

I have had 4-cylinder bikes that put out 3 times as much HP that were easier to work on and they needed less of it. My goal is to get back to the bike I remember before I was hit on it and this one is much nicer. So much to know on a simple 2 valve motor... but its worth it in the long run.

Well , are you braggin' or complainin' ? 

If I wanted Utopia , I'd take the blue pill and buy a sterile Honda and live a meaningless life .

 Instead , I will ride a M/G and enjoy my life !

Nope, neither. I have a sterile 1970 Honda 750 basket case chopper that I want to return to stock for the most part, a 1987 MG SP2 with 157,000 miles on it, and 1999 Suzuki Bandit 1200 with 38000 miles on it that just works and is my shop and chore bike and a 1981 Yamaha SR500 thats for sale and a 1973 MG V7 sport. I'm currently looking at a Honda Hawk GT650 as I want a lighter bike that has a electric start because after getting hit at 45 mph on my 2002 Lemans by a 84 year old man in a SUV... I limp and have a bit of trouble with my hip and kickstarting.... I'm busy trying to keep my head above water and its a chore.. gladly accepted chore for sure but never the less a chore for each bike done lovingly. Its what I like to do and when posting on here I'm really just hoping for a magic answer that solves the issue but when you get hit with tons of places to look it can be just as over whelming as the issue itself . My original post on here was about fuel injectors and having gone down that rabbit hole with thoughts and other places to look I realize that there is a ton to know. I had a 2008 MG 1200 sport that had the magic box from Guzzitech and it made the bike run rich as hell but it work well for the most part. The guy that runs that is pretty hard to talk with and so your on you own when figuring things out. I got that bike running well after doing all the things suggested which is what I will have to do with this one. Its hard to be a hobby mechanic and keep up on all the nuances of each bike, but life is short and I will ride as many as I can before I go... Sorted out a Ducati Monster S2r 1000 and rode it for a bit and then sold it to buy this bike which sat for most of its life... So I'm stoked that it is running and fine tuning will take a bit, but it sure felt good to ride it. So I choose neither pill and as far as a meaningless life goes.. 2 wheels are 2 wheels and when your riding it feels great no matter what you ride...  I have a vintage bike group and I have had probably 100 bikes in the last 10 years from Hondas to Ducati's to moto guzzis and two stokes and stopped short of buying Nortons and Velocette as it was above my wheelhouse in cost and mechanicing ... Its all for fun and if life is meaningless on a bike your doing it wrong... PS, the bike I was talking about was done by Mike Velasco who was a factory AMA race mechanic for 35 years and it was a Kawasaki ZX12r and it was anything but meaningless when hitting triple digits. It had 185 hp and 105 foot pounds of torque... it was scary fast...but damn it was fun for the 2 years I had it... Cheers my friend

Brother , I hear you on the "head above water" part. This version of a M/G needs appreciation more than adoration. It came out w/a lot of electrical problems that showed up in old age. The fuel system was tuned for an area that I am not sure exists . We all have found out the personality issues w/these bikes . If you need a bike to work on , you will enjoy this forum.  Internet communication can be difficult to interpret.  A terse response can sound like a smartass answer..

 The fuel system on these bikes require perfect tuning , just like EFI systems do on your car/truck. They are all tuned to borderline lean so if it goes any leaner it gets hairy.  Hang w/us and hang out .  Any time you need any or a lot of info , PM and I will give you my cell # .
