Just got it firing!
After many years of lurking, reading of other people's problems, I've now got one I'm stumped with. I've had my Cal. Vin from new, 2008.Never had a problem with it. Towards the end of last year noticed a bit of a misfire but thought I'd look at it in the spring.
Got it out a month or so ago and when I took it out noticed it missed, sometimes under acceleration, when accelerating again after having slowed and when riding in town. I also thought it was popping back, either through the exhaust or possibly throttle body.
I suspected ignition first so changed the plugs but made no difference to running.
I then changed the coils, leads and plug caps. I did this today. When I tried to start it, it took ages. (it normally starts no problem) When it did start it seemed to miss a lot more than before, and even got some smoke back through left t. b.
I took it for a short ride and it ran very badly, missing so much the tacho needle was bouncing up and down. I rode perhaps 4 miles with no improvement. Once back I removed the plugs. The right hand one was OK but the left hand one was very sooty.
Methinks the problem may not be electrical but fuel.
I'd be grateful for your thoughts. In the meantime I think I will put all the electrical stuff back as it was and drain the fuel out. I have already put some injector cleaner in the tank and done maybe 25 miles, but no new fuel.
