All of my pilot jets are absolutely fine....i am allmost sure that its not a carb problem anymore...
I follow your instructions today,about the spark plugs etc...
I swap the cyl1 spark plug to cyl2,now i think that the downpipes get hot all together,still no so sure though.
But the problem its still there. :'(
I also check the coils resistance,first and secondary,tps and all are in specs.
I have allready change the spark plug caps to ngk sd05f(no diffrence),but as i saw today they are 5k resistance,and yams are 10k.
I dont know if this cause any further problem,but nothing have change after all these changes and checks...
I am starting to think valve clearence... :eek :'(
It sounds like you're checking all the right things. I've been in your shoes so know what it feels like chasing a problem such as this. I wouldn't rule out carbs just yet. One tiny flake of crud stuck in a passage will stop the whole thing working. It needs to be scrupulously clean inside there. And if you've got a spark on all four plugs then it's unlikely to be electrical.
I'm not saying it isn't but the valves on the FZS/Thundercat tend to be pretty bulletproof. The bucket and shim design means the wear on the valve seat is compensated by the wear on the bucket. You'd have to be unlucky.
