Best porting for my riding style?

[RACxEMxWILLIE]

Thinking of getting a port job for my 03. Its getting about time for a rebuild. I was wondering what port job i should have or should i buy juggs that are already ported and bored. I ride mostly on straight away roads (dirt and pavement). Also, do I need to get a different head with smaller domes? Would it be a good idea to drop a few teeth on the rear sprocket and advance the timing. Thanks Guys!

 

Setup:

FMF Fatty with PC 2's

FMF pod filters

Boyeson Power Reeds

depends on your pockets. often, you can find a gould used top-end all mated up and redy to rock. or, you can port to what you want. a dune port should be fine for getting out in the open and letting her fly. might even get away with a drag, but you will loose a tone of bottom-end drive-ability if you need to get a little technical in the trails. advanced timing will give you that low-mid punch, but if you are looking at the top-end pipe power, it may be better off stock, especially if you go to smaller chambers. the size of chmbers should be best chosen by the guy who ported the cylinders, and the fuel/timing you run, as whell as the elevation/environment.

just remember: you can take your dune ported cyls off and drag port them, then put them back on with just new gaskets of you need to move the poer up the band, but once you go drag, there's no going back without new cyls.

Would agree with AK on all that.

• I had Kevin at HJR do a mx hardcore port job on my 99 and am extremely happy with the power gains and i do similar riding as you. I just told him what i had for pipes and he ported to pair them nicely and with +4 timing for added low end i am very happy with how it turned out. Give him a call!!
