PRIMETIME Posted June 10, 2012 Report Share Posted June 10, 2012 I'm looking at getting billet crank case for my drag bike just not sure what the pro's and cons are if any cons. Also, is mattoon machine the only place to buy them? Thanks for all the help!!! Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted June 10, 2012 Report Share Posted June 10, 2012 How big of a motor are you building? Quote Link to comment Share on other sites More sharing options...
PRIMETIME Posted June 10, 2012 Author Report Share Posted June 10, 2012 I have a cheetah with a 14mm crank, but I have a small leak on the bottom of crank case. Either gonna buy another set of stock case and have them trenched or go with billet cases. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted June 11, 2012 Report Share Posted June 11, 2012 They are bulletproof. I had my 18mm crank break in half inside mine and it didn't even scratch them. I put two passes on the motor with the crank broke in half and it didn't do a thing to the cases. Quote Link to comment Share on other sites More sharing options...
