Mods: Pt Hi Revs', k&n pro flow no lid, VF3 reeds, +4 Timing, Lightened flywheel
jetting: 290 Mains, DJ needle 3rd Clip, stock pilots, air screws 2.5 turns out
what could be the problem? I run 32:1 redline oil.
When I blip the throttle it seems like its wants to bog, and I have to mash it to get power.
Jetting is according to Duncan Racing, except they say use stock needles but the bike came with dj's.
when i turn the air screws out more it backfires, its real frustrating.
