06 Ktm 525 Exc

[rmrider125]

i recently just bought a 525 and when you let off the gas it spits and sputers. i was told that rejetting it would fix it and i did, and it helped but it still does it a little bit.
any suggestions?

i am guessing that you need to adjust the mixture control screw. also make sure you have the eclip in the right slot on the needle. i have had the same problem with my 450. the ktm air/fuel adjuster screw helps adjust things alot easier.

what did you rejet with????

r u using jets and needle position or did u install a JD kit????

the JD is a drop in and it works well......u can get it jetted correctly but it takes some experimentation...

...also the rfe ktm's backfiring off throttle is lean...

My brother's 05 did the same thing. The needle comes in a really lean position to meet some epa regulation or something like that :think: . Drop the clip two positions and then hang on! It really wakes the bike up. :cool: The JD jetting kit also works very well!
