hello,again, I've just fitted new throttle cables on my gen 2 fz1n ,I've never known such a hard fiddly job, in the end I had to pull the throttle bodies up out of their hoses to get the bottom cable in. when I start the bike up it misses on a low throttle and comes in on four after about 4000revs,it's running terrible,there is also a double click on the twistgrip which wasn't there before,on opening and closing as if the butterflies are out of synch.There is free play on the cables,I haven't a clue now whether it's electrical or what. Could I have disturbed any sensor or something ? there is a throttle position sensor on the bodies but I didn't knock it or anything.Any ideas ?
