Hi, All. Finally found new OEM rollers at MAS Classics , in CA. They had all the various roller sizes, both crank and rod. Has them in a kit (number needed), or you can get them in 100 count bags. Only a few dollars more for 100 count.

Dug up the part numbers and called them direct to order. Nice folks to deal with. Had all my stuff in one package in a few days. Probably has the cages as well if needed. Can order by the OEM part numbers.

I'll do business with them anytime. Has anything Colony as well. Check them out.

Good Old Motorcycle Co has them as well. Good folks there. Can even make bushings and stuff for you. Has complete bushing kits for vintage scooters. Check them out too for complete wiring harnesses. Good product, OEM style and fair prices. Good to deal with.

Very good. Sources for 52-53 crank and rod bearings were a concern. Thank you.

Hi. Did you lap the case race? Just wondering as that is normal procedure to insure round than lap to next std Oversize Rollers. I was going to say what size rollers? Even new std bushings are warped after pressing in. Run into this with mainshaft fit before. Everything new but std rollers won't fit until bushing was lapped slightly back to std after pressing in. Good to hear MAS & GOMS have bearings!

The person building the motor made his own roller pins after looking up and down the east coast and out west where he is located.He is a serious machinist made many of the pieces and executed the needed machine work to mate Mitch match cases and trap door
