Really nice finish on those. By the way, did you go with CR 26’s or 29’s? I have 26’s on mine. Pulls excellently. I’d also be very interested to see what hp/torque number you get if you bring it to a dyno. Our motors will be very similar but I have a 126-20 cam and ported stage 2.5 by Mreick.

Hi Dave I got the CR29’s. How does your bike feel to ride? I bet it’s a beauty.

Ah cool, once you get it running I’d like to know how the 29’s feel. Mine feels great. Excellent power and smooth all through the rev range. I did have the carbs and ignition tuned at a dyno though so it’s pretty dialed in.

Hey Dan, what's your issues with the transmission bearings? The groove I see is factory cut. I replaced all of my transmission bearings, but that's not necessary if they seem ok... The small ones are cheap and easy to get though. The large output shaft one cops most of the force, especially if someone has over tightened the chain tension at any stage.

Hi! I wonder if you can help me with a starting point for the jetting on my new CR29? I have a stock 650 engine with 4-1 exhaust and velocity stacks. I got my CR29s prejetted but it seems way too rich.

120 mains, 62 pilots, YY8 needles, 2.5 slides, and 250 main airs.

Sorry fella, I had to put my build on hold, so haven’t had it running yet. I’d be interested to know how you make out though, I may have the same issue eventually… Good luck!
