nightmarebanshee Posted March 22, 2013 Report Posted March 22, 2013 im having trouble hitting the powerband in 5th but mostly 6th gear..i think ive got the mains dialed in 270s to lean 290s rich 280 is what i have in it now and the plugs are golden brown but when i shift into 5th it bogs a little and gradually hits powerband and 6th it falls on its face i cant remember what i have the needle set at but could moving the needle up or down fix this problem? it is just broken in with t5s and uni air filter with airvents installed Quote
Zillaguy Posted March 22, 2013 Report Posted March 22, 2013 how is it with the 290's? Will it hit the powerband when it's rich? The main function of needle height is to richen up or lean out the transition from 1/4 throttle to WOT... Not sure needles are your problem, more times than not you want them in the middle....What gearing are you running? Quote
nightmarebanshee Posted March 23, 2013 Author Report Posted March 23, 2013 with the 290s 5th and 6th are flat but with 280s fifth gear comes along 6th still flat...im starting to think i have a coil issue i redid the caps awhile ago before i got it running and the right cylinder keeps backfiring so i switched the boots and same problem Quote
