Fcr flatside jetting for 2000ft to 5000

Recommended Posts

Tt please help? Got a used fcr flatside, the 3 jets in the float bowl are142, 45, 65, the CE is off now, will I have to change the air jet in the intake part of the carb also? Also float bowl bolts are Allen head now. Is it possible that it was jetted with a jd kit?

I thank you for any information you might have.

The JD kit uses genuine Keihin jets and a proprietary needle. The needle is identified by a lack of identification letters and either blue or red paint on the top surface.

 

The sizes you listed sound like stock DRZ400E jets.

pilot air, it should be 100.

 

3 options for the pilot circuit:

_buy 100 air jet and keep red and blue ports capped

_buy adjustable air jet (1 turn out = 100) and keep red and blue ports capped

_connect red and blu ports and keep stock air jets

 

at that elevation you can try stock dxp needle at 4th or 5th clip, main jet around 155. remove the snorkel from the airbox
