acroadam Posted February 25, 2011 Report Share Posted February 25, 2011 I was wondering since my banshee is bored .80 over, can I still do a dune port? Or do i need to buy new jugs that hasn't been ported? ...thanks Quote Link to comment Share on other sites More sharing options...
bansheesrtoys Posted February 25, 2011 Report Share Posted February 25, 2011 i could be wrong, but i don't think the bore size matters on porting.crank size however does. so if you have a stock crank with ported cyclinders, you can't use a +4 mill crank with the jugs.And yes if you are 80 over and want to port them you can.

crustydemon Posted February 25, 2011 Report Share Posted February 25, 2011 Bore size does not matter but the question is do you want to spend 300-400 for a port job on a set of jugs that are on their maximum overbore? Quote Link to comment Share on other sites More sharing options...
gotta_goatsfast Posted February 25, 2011 Report Share Posted February 25, 2011 I'd run a serval top end. Why? -Your cylinders cannot be worked anymore. If you can get away with a hone, then you can physically port them. But thats a lot of money to spend on cylinders that will need to eventually be refreshened. Since you cannot bore it anymore, the only option is to sleeve them. A machinist will have to bore the old sleeve out and press in the new one. Then that sleeve will need to be massaged around the ports to match the current port job. -You can purchase another set of stock cylinders and have them ported. For the price of another set of cylinders+piston kit+porting you will most likely be cheaper than the above option (after resleeving) -BUT, for a similar price to option two, you can upgrade to a cylinder with a whole bunch of modern technology that cannot be found in stock or ported stock cylinders. Call Jeff at Fast or Andy at M&M ATV and they will give you all you need to know about the Servals. Quote Link to comment Share on other sites More sharing options...
