dragbanshee98 Posted September 15, 2009 Report Posted September 15, 2009 can a 5mil crank be put into a 392 cheetah cub? by 5 mill do u mean a 4 mill long rod??? what stroke were the cylinders made for?? maybe im readin it wrong, but if it is set up for a 4 mill than you can get some wiseco 795 series pistons and it will go right in there... if it is not the crank im thinkin of then my stated opinion would also have to include boring ur domes some...

Hilarious Posted September 15, 2009 Report Posted September 15, 2009 can a 5mil crank be put into a 392 cheetah cub? where did you get a 5mill crank? Quote
4strokekilla1987 Posted September 15, 2009 Author Report Posted September 15, 2009 where did you get a 5mill crank? CRANK WORKS HOTROD AND I HEAR THAT TDR SELLS THEM Quote
coronakidd Posted September 15, 2009 Report Posted September 15, 2009 5mills run strong dont see why you cant just check to make shure it dont throw your ports off and youll have to run custom cut domes and maybe a spacer plate to put ports back in specs Quote

tony cub Posted September 15, 2009 Report Posted September 15, 2009 if that cub is drag ported you might have some issues,but if hasnt been touched,i dont see why not... Quote
4strokekilla1987 Posted September 15, 2009 Author Report Posted September 15, 2009 the cub is a virgin so I should be in luck do you tknow any one that has done this before Quote
4strokekilla1987 Posted October 6, 2009 Author Report Posted October 6, 2009 just thought id give you guys a small update it works i should have everything up and running by next week Quote
sleeper06 Posted October 7, 2009 Report Posted October 7, 2009 I saw a 5mil 392 cub in lawton Pa 300ft dirt drags,drag ported.I got him on the tree a few times but it ran hard as hell with snowmobile studs Quote

No Limit Powersports Posted October 15, 2009 Report Posted October 15, 2009 Yes it can be done but porting will be necessary to take advantage of the added stroke over the 4mm. Short rod motor 68 bore will run a 9768 series piston and you will have to custom cut the domes to get the squish correct. Quote
locogato11283 Posted October 15, 2009 Report Posted October 15, 2009 sounds like a hassle to me. i seriously doubt you will gain any advantage by going to a 5mm motor. id stick with the 4mm as parts are readily available. Quote
2bzy2p Posted October 15, 2009 Report Posted October 15, 2009 if you already had plans to do it like it looks why would you ask if it can be done? Obviously you know it can be done..weird.. Quote
