BK mod at 5000'

4 posts in this topic

If anyone has done the BK mod and rides at 5-7000' please let me know what settings your using. I'm thinking about doing the mod but am somewhat reluctant. Just want it to go as smooth as possible.

Firejake,

I'm at 5000' Ernie recommended 165 main,45 pilot it worked for him and it worked for me :)

My pilot screw is currently a 2 turns out, it seems to be fine, I'll see how she does on the track this weekend.

I also recommended one leaner on the needle. I also run race gas so I can jet a bit leaner than if running pump gas. That should be a good baseline to start. Don't forget, the higher you go, the richer it will run.

I have the BK mod on my 01 set at 0.3 sec. Otherwise stock running pump fuel. I am running a 165 main if the temps are around 40 degrees, 162 if around 60 degrees. Needle clip #2. If it gets really cold I may go to #3. #4 runs like crap, lots of cracking/gurgling sounds. Pilot #42, 1 to 2 turns out depending on temp.
