Jetting recommendations for SXR700 with head gasket & silencer Modifications

[greg]

Would anyone know if the jetting needs to be changed when the head gasket and silencer modifications are done on a 2000 SXR 700. If it does need to be re-jetted, what is the reccommended main jet, pilot jet and needle setting.
Thanks Greg

Nope, you can leave her stock without a problem. Just make sure with the thinner head gasket that you run premium fuel, that will greatly reduce the risk of detonation with the increased compression.

142.5 right across & drop needles 1/2. Those puppies need to be leaned down!
