Can anyone tell me what gears would be a good starting point for a stock CR 125 at Blackhawk Farms in IL?

19-23 or 18-22

This is a handy sheet if you don't already have it..
http://overt.ie/files/racing/technical/motor/gearcalc/Honda-CR125%20&%20CR80.xls

Be sure to verify your tire circumference before running a calculation. I've never run a moto at Blackhawk now that I think of it, but Keith's suggestion seems like a good starting point.

I plan on running my shifter at black hawk farms with CES in june, I want to do the rock island gp but the numbers are super low and this track is alot closer to me. I have a Pavesi ICC Smile

Rock island shifter masters got high teens for numbers so you are good to go there

Yeah should be 30+ shifters at blackhawk farms I would say. Now if we could just get as many at the other races.....

What jet setting do you run at Blackhawk? Should I keep them the same for sprint tracks or open up the main jet a little? This will be my first year in full competition for a shifter kart and Id rather not blow it up. I have been out of the karting scene for a while and running SCCA and Midwestern Council Sports Car Club

I could tell ya what I ran for a Maxter ICC but it might be different. You will be running a bigger main jet for sure, how much on a Pavesi, not sure.
