rhino 660 piston recommendation

[sexxy]

I am getting a good bit of oil in my air box. Tried the fix that puts a tank in line and has helped some but not enough. Been looking to do a 1.5-2mm oversized piston. Looked at wiseco, pro x, and namura brands but have not decided which. What do you recommend brand and size?

I think the 2mm puts it the same cc as a stock 700 rhino, is this true?

When I go to put things back together does the head gasket need to be bigger for the larger bore size or will a stock replacement be ok. Seen 1-2 different ones and some say larger gasket for 2mm over and others were stock. Any input would be helpful.

Personally, i wouldnt bore it that much.id just bore it enough to get it right. Power gains from boring arent enough to bother with. Your just wasting future bores...some may argue,but this is my experience.....stay away fom namura,trouble there.stay away from the ebay chinese cylinder kits also. Big trouble there. Pro x or wiseco or stock overbore sizes would be best....

i have done several with JE piston and Wiseco 2mm over 10 or 10.5 to 1 compression. i have used both stock and oversized gaskets with no problems. I would also recommend ARP head studs, Mudbuster cam and Muzzy dual exhaust. I did all to my personal rhino and it performed awesome. Hunterworks is a great source for parts and tech.
