What modifications should be be done to my new 2001 XR650R ?

3 posts in this topic

I have currently posted in the jetting form for a few answers for my elevation of 3,000 feet. Will be riding from 3,000 - 5,000 foot elevation.

Bike is brand new with only 22 miles.

Was stored for a few years.

I changed the oil and drained all old fuel, cleaned the carb, nothing plugged or gummed up.

Current modifications:

Calif. smog junk removed.

HRC exhaust tip on stock pipe.

Airbox baffles removed.

Stock air filter and backfire screen.

49 state intake manifold.

Main jet 175

Pilot jet 65s

B53F needle with the clip in the #3 position.

Not sure what setting the fuel screw should be at.

Bike is running too rich I think.

I have a white bros. E series exhaust ready to install.

What other mods(other than internal engine) will be needed to make this bike really rip.
