Vmax Guru Sean Morley told me a few things that might get the HP up but the most he's ever seen from a basically stock, carbureted engine is 135.. I'm not too far off. 2nd gear rolling burnouts are easy on this bike. 1st gear is ridiculous and the front end stays on the ground too... I want to sell but I'd never get back the 1300 hours I've spent restoring and tuning the bike.
Thanks for the comments,
Dave
