mikeymike1987 Posted June 26, 2014 Report Share Posted June 26, 2014 Ok I have a 10mil cub 1-5 n-down override I race at west michigan sand drag way. My second gear breaks 1st launch of the weekend everytime. I am going to indicate the shafts tomorrow to see if they are bent. Or will a bent fork do this? The teeth are stripping off the smaller gear dogs are fine. I weigh 230lbs this could also play a role I guess Quote Link to comment Share on other sites More sharing options...
Tedder Posted June 26, 2014 Report Share Posted June 26, 2014 We had that issue with our asphalt bike. Second gear is one of the weak links in a Banshee tranny. A billet second gear will stop the breakage problem. Quote Link to comment Share on other sites More sharing options...
mikeymike1987 Posted June 26, 2014 Author Report Share Posted June 26, 2014 I agree thanks for your help...everyone at the track is telling me I don't have enough power to need billet 2nd. What size was your motor? Quote Link to comment Share on other sites More sharing options...
RadarRacing Posted June 26, 2014 Report Share Posted June 26, 2014 110-120 can for sure break gears. Especially full size rider and good track. I think I will have a billet 2-5 for sale shortly. Quote Link to comment Share on other sites More sharing options...
Tedder Posted June 26, 2014 Report Share Posted June 26, 2014 It doesn't take a big motor to break one. The one we "learned" on was a little 358 cub. Since going to billet back in 2006 we've never once had another break. Quote Link to comment Share on other sites More sharing options...

mikeymike1987 Posted June 26, 2014 Author Report Share Posted June 26, 2014 Well looks like I'll have to bite the bullet $$$$$$ Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted June 26, 2014 Report Share Posted June 26, 2014 Asphalt gives ZERO FUCKS about your motor....... It will promptly make sure you know what the next weak link is. I've only seen one bike break 2nd on sand and it was about 120hp bike. Yet I've seen many failures on asphalt in motors from 90 hp stock cyls to 100+ hp cubs. That shit is aggressive and really takes it's toll on a motor. Quote Link to comment Share on other sites More sharing options...
