yamaha11 Posted June 18, 2009 Report Share Posted June 18, 2009 kevin did mine, its a 4mm dune port and it pulls so hard everyone thinks its a drag port. its a fun bike to ride with a 4 over swinger will not keep the front end down. i also had passion do one but im happier with kevin he will do more for me in the future.

dajogejr Posted June 18, 2009 Report Share Posted June 18, 2009 Dune/Trail bike: RB Racing out of Lansing, MI (awesome guy, awesome work, awesome price!!) Drag bike: HAVOC Performance, Grand Rapids MI. (Great work, motor runs HARD.) I like to keep it local, support the fellow MI riders and builders. Hasn't done me wrong yet! :thumbsup: That's interesting...I did not know the Havoc guys did porting, I only knew they did polishing and very nice chassis work. It's always good to see Jeff, Jer and Linds at the dunes and the track. (At the go carts too...lol) Quote Link to comment Share on other sites More sharing options...

I do not believe they advertise for it or anything.. Again, its all about keeping it local. There is no way in hell I will let these cylinders leave Michigan if I ever decide to get rid of them. They are BEAUTIFUL cylinders. I know a lot of pride went into them, so Ill do whatever it takes to respect that :thumbsup: Quote Link to comment Share on other sites More sharing options...

400rednEX Posted June 19, 2009 Report Share Posted June 19, 2009 i got a gorr port before he closed shop. its the all around port and it is real torquey, but in the dunes i think a little more top end would be nice. Quote Link to comment Share on other sites More sharing options...
