Hi I have problem with my never-failing 426 ;-) The bike never failed till yesterday. I started it after 3 weeks. First it flood the plug ;-/ I though..it could have happend after 3 weeks of cold weather and beijng started in -2. "Last time I rode the bike it was -5 a lot of snow and I had graet riding with no problems." So I've changed the spark plug into brand new and the bike started with 2nd kick (I thought :usuall). But when I've turn off the choke it died. I've pulled the choke agian and start it and I was holding the throttle and turned off the choke. The bike was running but without idle, I had to hold the throttle to pick up revs higher but after few throtle blips it started to hold idle spped (I thought :dirt in starter jet). So I took a ride but when the bike was really warmed up it stopet on idle and it was very hard to start- 20 kicks and at last it started (with idle setup a little higher). I arrived home and made fast jets cleaning. Next day I've started it wih no pain and agian after arround 3 km when it was warmed it started to have strange idle. First it was like to high so I simply lowerd idle speed. After next few km the biked died on idle and was agian very hard to start. I;ve made carb cleaning again (all jets:air and fuel). I've started it with first kick and it was ok but after warm-up it died again on idle and was hard to start. For me it seems like fuel problems, it works fine with high idle speed (not normal) but when I lower them down it will die when hot. One more thing after it died on the jurney I started it with many kick and after that it had problems with hard acceleration form low and lower middle revs. It is hard to tell what was going wrong (my english is not enaught) it was something simmilar to missfireing or being to rich. I,ve never had problems with jetting (winter, summer). I've checked the valve clearance and it is like it was after rebuild. (new piston, rod, seals, and few gearox parts last year) New spark plug Carb seems to be clean after 2 cleanings. Please help me, maybe it is problem connected with TPS or electrics? The spark plug connector has few rubber splits but I've never had probles with this. I don't know what to do.
