Exup 1000

I bought a cheap 18mm long reach socket and got a engineering place to turn it down on a lathe.

Thanks all.i forgot to mention,after I start it,if I shut off the choke,the bike cuts out and won't start or run without it.i changed some of the plug caps for Ngk ones as well as the standard ones were arcing off the head at the top of the orange seal.not sure if the new caps are any good.they were...

Thanks for all the advice.it used to run badly(no.3 cylinder wouldn't run under 3k rpm)sorted by removing the resisters in the plug caps.ive stripped and cleaned the carbs more times than I can remember.tubes look ok and it has a stage 3 dynojet kit fitted .i borrowed a cdi box,furs pump resister,an...

Takes a lot to start the bike.eventually starts but won't pick up.only with a lot of feathering the throttle,it might make it up to 3k rpm.a lot of spluttering and backfiring.the headers start to glow.it went from running reasonably well to this.i have checked the valve clearance and a good few were...

Hi all.I whipped the engine out of my RU to drop if off to my local bike shop.i explained the poor running and said that I had measured the valve gaps and they were too tight .the mechanic said that it didn't sound like valve clearance trouble,more like a cracked liner.anyone have any experience of ...

Thanks,reckon it would make life much easier to whip it out.something to get stuck into over the winter

Hi.just wondering is it awkward doing the valve shims with the engine in situ?
I've no problem whipping the motor out to do them

Ive tried swapping the plug caps.had ngk ones on them,still arcing.replaced originals and wrapped them with tape.still arcing.borrowed a full set of coils,still arcing.the only spark il see soon is out of a Zippo and i torch the bastid.

Anyone know the cause of plug caps arcing off the head?been trying to get both my fzr's running but both are suffering from it. On both bikes its cylinders 3&4.i borrowed a set of coils for the 1000 but those are arcing also.at my wits end with both bikes now.always had yamahas but seriously get...

Il try spraying carb cleaner or thinners near the inlet manifolds and see if it shows up any leaks

Only getting around to look at the bike again lately.the coils,ecu and fuel pump resister have been swapped to no avail.still running badly.even if the carbs were out of balance,surely it would at least run half right.can borrow a set of carbs but they,re not in the best shape due to being on a bike...

Hi all.Im making one last ditch attempt to get my RU running right before i loose the rag and either sell or scrap it.a few years ago it started acting up.not running on cyl no 3 under 3k.i sorted this by removing the resistors in the caps.that solved the problem for a while but it came back with a ...
