I'll caveat this by saying it is NOT legal for CSBK
A friend of mine has a Norton Motorsports GP Spec motor for a 400 Ninja (Twin). These are/were built by Jesse Norton from San Deigo.
About 1 hour on a fresh rebuild, 65+ reliable rearwheel HP. I believe it originally came from Rocco Landers bike. If your interested I'll put you in touch, i said I would post it here for him. It would be a nice bike for the BOTT.
I'll post the Dyno when I get it.
