Hi guys I have a drr 70cc with a Athena cylinder and there is currently a malossi crank with a 10mm wrist pin bearing with a unknown amount of time on it as I bought it ( the Quad used ) anyhow after the second cylinder this one only lasting 1 day and the wrist pin bearing failed what is my next move as we race next weekend. Help this is getting $$ by the way the jetting looks good and we are running Klotz R-50 at 40:1 you guys think it may need a crank ? let me know ASAP Thanks

did you use a used wrist pin , and when your one that failed did you lose the needle bearing s in the crank case .. if you did I would change the crank , or take it apart and inspect it .. I would contact marc at hotquads he has some good deals on engine kits .and will work on your budget .he is one of the best engine builders out there. and he gives good tech help
