Hey riders! I have a little problem on my bike.. when I try to adjust my right side exhaust valve it looks like I can get any feeler gauge down there..its kinda tricky to get down there and it feels like maybe I am compressing the valve spring down because it gets kinda hard to get it in there but it still goes without pushing like crazy.. I left it to where it seemed harder to slide it in and the bike runs fine but I’d like to have some other opinion just to be sure! All three other valves were easy to adjust its just that one!
What is the highest compression piston I can use on 93 pump gas
I bought a 2010 KX250f from a guy who bought the bike brand new back in 2010 (only had 1 owner). The guy put a high compression piston in this bike. Also he was pretty much running straight race gas because when he took it to the shop, they must have messed with the jets because they weren’t stock anymore. I got new jets. Currently at...........………Pilot Jet - 42. Main Jet 185 I’ve messed with my air screw and tried a few things out but I still have to kick my bike like 30 times before it finally starts! The piston is supposed to be high compression but it doesn’t feel that way. I’m thinking of just replacing it and going back to stock??? Any thoughts? Ive read that valve clearance is an issue with this year bike... Also that Kawis need a little throttle when you kick. It ends up flooding every time. Send help please!!
