Balzout Posted July 24, 2009 Report Posted July 24, 2009 Please bear with me on this one as I have no clue as to what timing a duner is set up to as compared to a drag port. So I guess my question is directed toward these people. I love my banshee and I like to run hard, it's just that I want more power but I still need to be able to ride with my family. My son and I just built an 872 raptor that I'm gettin tired of looking at the tail light of. I realize that a 10mil is not needed to out run his bike but I was wondering why this much crank had to be labeled "drag only". I heard that the port timing of the cylinders that were avail. for the 10mil were all centered around high rpm power. So here is my question, can a different height cylinder be used, either from a longer or shorter stroke casting, then use spacers or mill the cylinder, to correct the deck that build a motor that has a tons of power everywhere? Or did I hear it wrong and the 10mil already is a handful top to bottom? I really don't want to put together a 4mil just to have to change it down the road. Thanks Quote

Thanks A 10mil can be a duner no problem. :thumbsup: Quote
firebanshee Posted July 25, 2009 Report Posted July 25, 2009 Buy a power valve set up and have the best of both worlds :cool: Quote
docjcwatson Posted July 25, 2009 Report Posted July 25, 2009 Tyler (Loco) has a 10mil that he beats the piss out of! I've seen many videos of him jumping the thing. A couple different guys on here have 535cc Cheetah's that they use for a trail bike! Those have 10mil cranks in them. I would go for it. It would keep up with that Raptor, that's for sure. Just get a lockup and a duneable trans. Quote

Balzout Posted July 25, 2009 Author Report Posted July 25, 2009 you could do a 7MM too and have the cylinders ported to give you all around power. I would suggest contacting JSR Performance. They ported mine and with the carbss on race fuel it made 85hp to the wheels and 50ft lb of torque but the nice thing is the power comes on down low around 4000 rpm compared to the cub cylinders that have very little power until you hit 6500. Thanks for the reply's guys. This is what I was hoping would be the case. So loboboy on your cylinders is there a 2mil cut into the head and the rest of the height made up in spacer below the cylinders, then the timing is corrected with a grinder? Is this the biggest crank you can run with stock cylinders? I'm not leaning toward stock just trying to get an understanding. Thanks Quote
