I recently did the MCCT job and after buttoning everything back up my bike started to die at idle. When the engine is cold it idles just fine; but as the bike warms up it just slowly dies; revs drop in spurts and after a while it just dies. It first started on my first ride when after about 5 minutes of riding the bike became difficult to accelerate and eventually died. After it cooled down I was able to start it again and ride far enough to get it up the hill I was on.

I was poking around and found that if you're running rich your bike gets worse as it heats up which sounds like my problem. But also, what are the chances I messed up my timing? I checked the rear cylinder and make sure the timing was fine there; I haven't checked the front yet (mainly because its just a pain to get to). And because I know you guys are going to ask, I have already synced my carbs.

So could I be running rich? Is my timing off? Could I be something else? Any help would be appreciated.

 

Possibly, too tight when it warms?

 

I'd suspect the tensioners may be too tight as well. If everything was ok before the swap and that's the only thing you changed...
