carb problem

[patrick_777]

I found a couple of Quim's posts that state it was 1 5/8 turns out from factory. It might vary though. Are you using a new jet?

You need to start bike and let it warm up.Next you need to slowly turn screw out until engine starts to stumble,than slowly turn screw in until engine stumble,than out till engine idles best.About the middle of both extremes.You should start with screw out about 2 turns.Eight turns out bike is not getting enought air to run properly.

Be careful with that. A LOT of us have been fooled by what looks like oil stains on the fins.
It may NOT be that at all. There is at least one (maybe two) threads about that on here. It could just be left over "shipping protector". Try to clean it off and if it is stuck on like concrete, that's probably what it is......and not a real oil leak.

And, a head gasket will not usually have any impact on how the engine actually runs.......unless it is REALLY bad.

I can also say i had the same problem with my GZ...fixed itself with Lubrication and it was fine

good luck out therre

Yup. A pic will help tell whether or not it is...
