Title: 100 jetting
Post by: sixdazed on August 31, 2011, 03:16:58 PM
Just found out i got a wrong piston for my d 125 motor.May have to put it together as a 100,maybe use same jetting or a touch leaner?Brian,anyone?.It's got a 28 bing-jetting specs for Socal might save me some time.I'm guessing about 5k feet at the ranch.Any help appreciated.Thanks,

When I took off the 125 top end that came on the SoCal Berkie, all I did was go up one size on the pilot, the needle/needle jet and the main were perfect. I would start with the 125 jetting and work from there.

Also, I forgot to add, I also have a Bing, bit it has a custom pipe with a smaller diameter and shorter center section so it might jet a bit differently than one with a 125 pipe. I think my jetting is 135 main, 35 or 40 pilot, and I dont think I ever looked at the needle jet. I can get the exact jetting if you want, I need to take it apart and order a new needle/needle jet anyway.
