Performance Crankshaft

Post by czechojo »

anyone have any suggestions on a better than stock crankshaft for a RH50?
preferably one that can easily be swapped out with the original

Athena makes a good racing crankshaft for the roughhouse. https://www.scootertuning.ca/en/cranksh ... -10mm.html

Me personally I have modified my crank case just a little bit to fit a 2ab ministroker crank

Help! I lost it! What size and thread is that nut which holds all on the crank shaft?
Thought it was 10 mm
Machine screw with flanged nut to 15mm
