dirtydownunder Posted April 6, 2011 Report Share Posted April 6, 2011 , the only real way to tune an engine is with it running so you would have to pay the builder for build time and tune time. the builders are pretty dam good and will get you real close, and with them in your ear and you just changing jets, youll do it easy !, then in time you will "feel" how to jet your self. always jets richer to stay safe and lean it out to perfection. check ya spark plugs, they tell you whats happening in the engine. wet/dark too rich - dry/light (looks like its been hot) to lean, there is pics all over the net, search "plug chop" to see colours differences. your builder/porter, if you give him all your riding details, they will get you pretty close anyway...

willaduncan Posted November 21, 2011 Report Share Posted November 21, 2011 Either Jeff at FAST or Kevin at HJR are both very reputable builders and outstanding guys, I chose HJR because he gave me a military discount where as FAST wouldnt but I have bought stuff from both companies either way you go you will be happy, with no discounts they are very close in price btw!!! I did the HARDCORE MX port with bore and hone of my cylinders from Herr Jugs and I stomp the shit out of any 450 or raptor modded or not where as before the port job I was getting eatin by 450's and shit all day so you will be happy with a port job Quote Link to comment Share on other sites More sharing options...
