we will have a pic up on our website within 1-2 weeks. our web designer is working on a major update for us.
we will be doing some price changes too. you can purchase the hi-flow intake for $179 or $199 with the outer wears. the nice thing about the speedwerx setup is the added crankcase breather and the k&n filter is larger.
also the price of the speedwerx exhaust system will be $399

speedwerx, your post is unclear



<< if you use a dyno jet kit, most pipes including ours uses 148/146 jets with our hi-flow intake setup. if you are using mikuni jets you would use 165/160 in most cases. if you use the stock needles, raised to clip 5, turn the air screws out to 4 turns, and 175/170 mikuni main jets, this also works good but the dyno jet needles are richer and will rev quicker. >>



I agree that dynojet 146/148 and mikuni 160/165 jets are comparable. How are you jumping up to 170/175 jets??

Are you saying to use mikuni 160/165's with dynojet needles?

with the stock needles raised to clip #5, it is leaner than the dyno jet needles in clip #4. even though you would think of the needle affecting the mid range range mostly, it does have a direct effect on the main jet slightly. with the stock needles in #5 it just ran way too lean with the smaller mikuni jets. my 2001 i had 170/165 main jets with the stock needles raised all the way up, but my 2002 i needed 175/170 main jets. i understand there was a timing change so that is the only thing i can figure caused the difference in jet sizes. i never ran the dynojet kit in my 2001, but i did notice a difference in how quick the motor reved when you were grinding through the gears when i installed the dynojet kit on my 2002. i really liked the improvement. when it was colder out i even noticed a slight surge in rpms when it revved up with the stock needles. that surge is gone with the dynojet kit.

speedwerx,

Thanks for the response. I will check the site in a couple weeks or so. I'd like to see it installed before I spend that kind of money.
