little help with the fuel screw
Posted November 08, 2011 - 04:30 PM
If the Fuel Mixture Screw collar is above the main jet access bolt, it takes an FMS01. If the collar is level with the main jet access bolt, then your carb takes an FMS02
Not sure what they mean by collar.
I know im still a rookie wrencher

You want an FMS01 - Be sure it is Stainless (like from Kientech) or Brass, Avoid the alloy ones.

Fits Keihin Pumper Carburetors ('FCRMX'). This part fits all YZ/WR 426F, 250F and 450F bikes, as well as the YFZ quads. It does not fit the YZ and WR 400Fs (uses FMS02). FMS01s fit all CRF450 and CRF250 Hondas, but, they do not fit the 450cc based Honda quads. They fit the new Kawasaki KX250F, and its yellow sibling, the Suzuki RM-Z 250. They fit 03 and newer KTM 'RFS' 4-strokes -450 and 525. It will not fit 02 and older KTM 400 and 520 bikes (uses FMS02).
Please tell me I didn't order the wrong one...

However... it is an alloy screw and not one that I'd reccomend. This is a short list of good ones:
All have brass or stainless ends.

I've been wanting to mess with the jetting, so I decided to order up a JD kit. I have read on here that I needed a fuel screw too, so I ordered that Zip Ty unit.
After looking my bike over a little last evening, I realized that my bike already has an extended fuel screw. I am going to really be pissed if I find out that it already has the JD jet set up too.
Sometimes I amaze myself with how stupid I can be.
