Hello, I've got 1995 YZF 750R (import) don't know where from though.. doesn't seem to want to rev above 9-10k without spluttering and missing, idles rough as well but goes great in between..? Only recently got the exup working, has improved mid range and not so much of a flat spot at 3k, new plugs and caps, (they were shorting) but still hasn't made much of a difference, and carbs have been balanced..alledgedly

Anyone out there struck this before or no of any reasons and cures...? i'm stuck! cheers Pete

is the air box fitted correctly

they can be tricky and any leaks will screw up the high rev fuelling

has it got a dyno jet on it ? are the carbs set corectly? if its an import depending on where its come from has the carbs got the correct jetting ?

when was the valve shims done last ?

might be none of these things but might be worth doing some cheaking

sounds like carbs r full of shit maybe needle and emulsions r shot and defo check the valve clearances

valve clearances a defo mine well out about a year ago

but not a job if your not very clued up..

cab balance is a good start best thing to do is get it

on a dyno and let some one do that..
