i cant afford both at the moment but was planing on getting one of those BBK off ebay for $770.and port and polish it myself

maybe get the bbk and wait till i blow the bottom end up then get a 4mil?lol

 

call a sponsor and talk to them about porting your stock cylinders. either stock stroke or 4mil. it will be faster than ebay stuff.

Big bore kits are a waste of money. Hit up Kevin at Herr Jugs Racing. He's got a deal goin right now on 4 mill cranks for $365 trued and welded. Add another $300 or so for porting and you've got one hell of a runner!

for what its worth a ported stock stroke will out run alot of stuff...

 

Maybe in drag form. But a stock stroke dune ported bike will not outrun a dune ported 4 mill so long as both bikes are set up the same.

what about a ported bbk?lol just had to ask

 

Big bore kits add nothing to performance. You'll basically be paying $800 to tell your buddies you have a 400cc (or whatever size you're lookin at) banshee. A ported bbk will run the same as a ported stock cylinder bike. 4mill + port work is what you're lookin for.

Just so you know, once you've ported your cylinders for stock stroke they will no longer work with a 4mill crank. Also, I hope you know what your doing, because there's more to porting cylinders then just hogging them out with a dremel. Good luck.

im just doing a clean up job for better air flow.im not going to screw around with the port timings.

i did my polaris 580 tripple and the thing is a screemer and my boss has one done by so called pro's and yet he is impressed with the way my machine rips
