Hello all. I just joined the forum today after many months of reading the threads. I have a question about jetting my raptor for winter riding. I have a full yosamera pipe, stage 2 cam, up graded valve springs, 12:1 piston, K&N clamp on air filter, and some porting. I am still runing the air box lid but have two 2" holes in it. The jetting is 170 & 175 and is spot on at 75 degrees air temp according to the dyno. I have tryed to run it now and it runs very poorly. I know it is lean because it runs better when I choke it. The temps are around 30 degrees. I would like to know were to start with jetting. The elevation is about 575 Feet above sea level. Any help would be very helpfull. Thanks again.

 

I would go 190/195 and fine tune from there.[img]i/expressions/face-icon-small-wink.gif[/img]
