Oldmini are not dead look at the price now. We will pay for memory's. We want grandkids to have the bikes we had. Americans can make a great bikes. It's the lawyer's that ruined it, the kids got hurt not there fault It's the bike.
I know it's the wrong intake, it's late year 71 but does it have the right throttle linkage I think. But I was tickled to find a 71 motor. I want to get rollers back to stock. I'm on my way to do these classic justice, found 12" wheels for them more to come. I need 1 more motor. But give me time...
My thoughts are the same. I was thinking 11/8 stock on hand body 2 I inner bearings 13/8×3/4 radius to 5/8 with the flange bearings caps . I will keep you posted
Wow thanks everyone the info is awesome thanks. Iam new to rupps 1 is just a roller. I found a a period correct motor but it is a 6hp .I was going to over build it till I can find the right period correct motor.
Well just got my first rupps the spares are messed up jack shafts 1 is stripped the other has weld repair, 1 with welded sprocket. I can make new 1s I was thinking double bearing large bore sprocket not sure on the motor side.
Iam a machinist I have a 71,72 rupps the jack shafts are shot I would like to make them out of 4340 and beef them up. Has anyone else done this yet. If you did can you give me some information on how you did it and what bearing etc. New to this.
Iam a machinist i have a71 &72 rupps i want to make better jack shafts with 4340 steel. Better and stronger than original. Has anyone done this before using better bearings etc can give me some insight information would be greatly appreciated.
