FZS600 '99: Perfomance issues

[Toympas]

Hello i own an FZS600 and i experience this problem: The bike will run good and smooth after i change the plugs for - say - 1000kms and after that it will become choppy and loose alot of torgue down low, it short it feels troubled and weak.

And again it will shift back to optimal for a few hundreds after I change the plus and so on.


WTF is wrong, any idea?:spank:

Sounds like something is wrong with the ignition system, and new plugs just give it a temporary fix. A few questions though, how do the plugs look when you pull them? Do they look oily or overly dirty? Do they look fine, like barely used plugs should? I'm thinking if it's not electrical, it could be something else that fouls up the plugs in short order. If even one plug gets fouled, then you could see a power loss, but it'd have to be fouled really bad.
