thank you. today i put in an 81t spur (but had oter things happen is i only get 8 mins of run time.. no i don't hit the walls ,at lest i didn't today and i don't hit them as much as i did one year ago) any way my point is i found out that my pulleys are 21.. no for real 21 no the main shaft that has the spur gear on it!
it did seem a little faster. i only got to try one pinion
but maybe next time i can try more
thank you to every one that has helped.
any one have an tekin rs/ rs pro that they want to give away? or at lest almost give away?
