Hi to everyone who is going to help me solve this one:
XS 1100SF, 51K, had it for 4 years ran immaculately. never a carb problem, cleaned and adjusted it every year. started up with a fraction of a key turn any day, any season. it was time for to replace a noisy timing chain, and in the interest of time, took it to the Yamaha dealer.
I then got a call; chain is in, noise is gone, but it will not run right. It sure does not. I am pretty experience with carbs but this one get me. Problem:
it will start only with the choke wide open. ruturn the choke and it will stall. if kept alive with the throttle, it will stutter and spit like a wild cat. if reved up it will not come back down from around 4k rpm even though the i can see the actuator come back. when it does, it will not idle. when i hold it for idle with the throttle, like i said, especially #1 carb will spit and back fire consistently, and the others occassionally. fuel flows normally
they claim they did not touch the carbs. by the way, when taken out on the road, it will initally accelarate normally, then when you open the throttle to accelerate again it will choke and boge down like fuel starvation. if you stop and accelerate again, it will run up normally. when cruising, it will hesitate slightly.
So what gives, what am I missing. I have taken it apart, inspected every orifice, adjusted all to spec and so on.
Please, everyone that has any ideas let me have them.
Thanks y'all; if I can be of ANY assistance, please do not hesitate.
