Wouter Smoors

Dear Rob, thanks for the respons! I don’t know what has been done resently because i bought it like 1 week ago and only checked the following: oil, oilfilter, air filter and carburator rubber rings. So i checked an leak and with aerosol it raises the rpm but only when i spray it random and not on a specific place!

Dear fellow motorcyclists, My name is Wouter and i am from the Netherlands. I bought a bike a few days back for some beer (suzuki gsx600f from 1990). So since yesterday i was able to start the bike after checking the basic things. So here is the current problem when i start the motorcycle, when cold it runs nicely at 1400 rpm but then when i turn the throttle for the first time it will only drop back down to 3000-3500 rpm after the revv and stay there. But that’s not the only problem. When i rev, it will first drop 500 rpm before rising and after that the rpm will decrease really slow. I hope you guys can help me!
