My new project...a 1974 Yamaha MX100!!
Will look great sitting next to the 360.

I think it would be worth a phone call to Rick Hovat, he always has bitchin' stories and a wealth of knowledge. Maybe even a phone call to Vance at Q&E, hell how about Jerry Curl?!! I'd like to think a 74-75 YZ125 engine would fit, then I could just sleeve it down to 100cc. A top end off of a 76-77 YZ100 would be illegal I believe?

I need to take the front end off of my MX360 to install the RT emulators, so I could try to see how it would work on the MX100?! It would be nice to have a bigger drum up front. Any ideas on modifying the rear end / suspension, maybe leaning the shocks forward?
Here are the rules below...Can anyone tell what rule I'm already breaking?!! hahahaha
