Recommended Posts

05 crf450r tokyo mod carb, fmf 4 pwr core mega bomb header

my bike is a ***** to start cold it will fire up then die, or just not kik over at all and have to push down a hill and dropp into second gear to get going, once running i cant get the right mix of a good idle and no popping on decell. iv messed with the idle and fuel mix for a few days now with no luck, once its good and warmed up it runs fine except for popping on decell i keep increasing the fuel mix and it dosnt go away, any ideas?

clogged pilot jet possibly.. when you remove it, remember that not just the 8 tiny holes on the side of the jet need to be open, but also the tiny hole right down teh middle.. don't ask me how i know about that now .. LOL.

Also, take a few moments and pull the valve cover off and check your valve clearances.

adjust the idle

clean the pilot

make sure the hotstart is not stuck in the carb open and there is slack in the cable

inspect the valve clearances

Make sure you dont have an intake leak somewhere from the installation!
