Hey, I'm a student technician and when I graduate I want to build performance race vehicles and start a company based around it. So I picked the R3 as a starter bike to work with that I could build as a pure track bike and then my brother could race it after he goes through racing classes. Now my question is does anyone think that a Yamaha Banshee 350 engine would fit into the frame of a newer R3? If so I could have an air cold parallel twin 2 stroke and save weight by not having to have all of the electrical start equipment on the bike. Plus the sound would definitely be a good bonus considering my reasoning behind racing is for the experience and to impress potential customers. ?
