Can anyone repost these curves?

Thanks for the info, Adam.

I am not sure of the answers to your question either. However, I do have a complete 2000 cr250 ignition system I would trade for your stock 500 system should you choose to go that route.

Is there enough clearance at the swing arm to fit a 140/18" rear tire?

Does anyone have experience with these?

Would the Reed spacer be needed with you're pulse charged intake system? Always wanted to fool around with that after reading a write up by Eric Gorr on it.
Check your PM's.

Any comments on what needs to be done and how suitable is this bike is for shoe horning a 500 motor in it?
My last 500 was a 03 Service Honda 500 af. Was very happy with the bike, but their prices are very high now and I think I can do it myself pretty cheap comparatively.

Or maybe I MS has a blue print for them?

Easy to make, you would just need enough sets to get the price down and make it worthwhile for the machine shop making them.

I believe Mr. Hall is spot on. One of the best snowmobile engine guys I know breaks his motors in on the dyno by bringing them up to temp, then making a series of pulls the last of which would sometimes make the expansion chamber head section start to glow.

In a CR-500 the rpms are pretty low. I have no reservations in regards to using Yamalube 2R at 32:1 for trail and MX use and at 20:1 for the dunes. It burns very clean at these ratios with the caveat your jetting is on, protects well during long term storage (like our 6month long winters..) and ...

I want a set of these really bad. Anyone happen to have any or know where I can track some down?
