I picked up a 6.5 from Harbor Freight yesterday and got it in the T-bird. To save time yesterday I just used the attached gas tank on the engine to get it fired up. Looks like the clutch that was on the stock H35 engine is junk. I could rev it all the way up and hold the bike back with my hands while standing above it. Looks like I need to start looking for another clutch. Any sugestions? BTW throttle hook up was really easy. I'll get some pics up later.
