Post by: dean.lilley on April 02, 2014, 04:27:48 PM

Hello im rebuilding a 92cr250 and was wondering if anyone knows the difference between the WORKS 95 pt number 0446 and the 92 PLATINUM pt number ph92250p?
I just bought the 92 as the 95 is getting rough

Wow! no wonder.  Where did you come up with a 195 main?

Here is a good baseline jetting start using the PWK.  Tweak it from here for your temps and
altitudes: 168 main, 55 pilot, 1370M needle with clip on 3nd and the airscrew 1 1/2 turns out.

The 195 main came with the pwk carb from a hm honda cre250? I put it back to 165 for the minute, just wondering if the 16oz flywheel dc set up would make any difference?

I'm hoping that number is a 1369, if so, you should be good to go for a baseline.
If it really is a 1360, you'll need to swap it out.  The needle will affect performance
from 1/4 throttle all the way to where the main jet takes over.

From the pictures, looks like a nice ride.

I just sent someone some pictures on that on another site.  If that wasn't you, let me
know and I'll send them to you as well.
