my family and i are going to oregon at winchester bay. I live in Colorado and I know I need to rejet my carburator. We ride from 4400 to 8000 feet. Let me give you some information about my DS.
2001 DS650 with the following mods
14:1 HPR Piston
Webb 109 Cams
Ported Head
TM45 Carb
Big gun CDI
Ported intake
Ron Wood exhaust

This is what I am running, at 4000 ft. 140 main jet, 25 piloet, e clip is on 2nd from the top. I am running a KN filter, directley on carb, no air box. Running lean spray nosle, pump is set at 1/2 throttle. I am running 50/50 on the fuel, can I run 50/50 at sea level or do I have to run 110 racing fuel?

If you guys good help me out, I would appreceiate it.

Thanks, Rob

 

run 110, i run 115 at 800ft elevation, on 13:1 just to be safe.

richen it up a tad and you should be good.

 

YOu will want to run 110 there. The air is usually a bit wet, so the 110 is fine. That is what I run on my 14-1 there. On a similar build with the TM45 we were running a 155 on the main. Pumper should be fine. Not sure what we ran on the Pilot jet though...

When you gonna be there. I will be there from June 29- July 5th. Look for 3 Black DS's running around, and come say Hi....
