KDX C Model Jetting

Post by Gazza »

So I recently rebuilt my 88 using the new wiseco piston released, along with a re sleeve and all relating bearings seals etc.
The bike has great torque and pulls well into the top end
I also installed the Boyesen reeds.
Does anyone have experience with jetting issues as the bike over revs on overrun especially when negotiating long rock decents.
She hunts for a while before revving high for approximately 10 seconds.
It sounds like it's leaning out as if the fuel tap was off. Def no air leaks present.
Cheers

Cheers !

Was a bit low, also found the main jet cracked 90% around where thread meets jet body.
Guessing it's been over tightened.
