I bought a Fantom '05 FR21. About 2-3 min into a race the motor Leans out,
Idle shoots up as well as the temp(300-340deg)
I have checked everything twice for air leaks.(none) I run 20% O'Donnell and a MC9 plug. Im also running the motor in a Jammin X1cr (with the new tank).and the JP1 pipe. Thank you for any help you can give.
