RMX 250 hard starting issues
Posted: Wed Jul 30, 2014 10:34 pm
Hey guys hows it going?
Recently bought myself a beautiful example of a 99 rmx250.
Upon buying this mean machine, i found it utterly impossible to start. Did some research and found that the stock PJ carburetor was a pile of poo, so i quickly purchased a short body PWK38 Airstriker with tps and solenoid.
With the new carb attached it starts after 4 kicks when cold with the choke on, when warm it will not start unless A) clutch start or B) let it cool down for about an hour. Jetting is #178 main #52 slow jet and the needle clip is 2nd from top. Sometimes when hot it will start with 1/8 throttle cracked, so im thinking maybe the pilot is too rich? Reeds are brand new as well pretty sure they are boyesen powerreeds.
Also did a compression test and it came back 150psi, upon pulling the top end there was some serious blow by on the piston, the bike has 9000kms on it leading me to believe its only been rebuilt once in its entire life.
Is my float level too high? too low? pilot jet? or compression?
Any help would be great guys!
