I agree with ^^^^^^^^^^^^^^^^^. I had my 34mm pj's bored ,,,,,,,,and since then it had ran terrible (with no bottom end)........In my stroker i now have 28mm d-slides......and it rips hard!!!!!!!!
I have to disagree...Alba..in SD had done a dyno with v-force/stock reeds..........and beleive it or not stock reeds did not trap HP like v-force.......BUT.........they do show improvment on Motocross bikes!!.........
