nicktoney Posted March 12, 2007 Report Share Posted March 12, 2007 alright... i have a 4mil 5 mil longrod stroker.. FAST dune/play porting, trinity IV pipes, v3 reeds, Boss intake, 33mm PWK's, NOSS head 20cc domes, +4 timing, stock box no lid w k&n clamped inside... my altitude is 12-1400ft... temps are around 50 degrees.... would a 145 be too lean?? i had 155's in when it was like 10-20 degrees out and the top end would just sputter gasping for air because it was way rich... what everyone suggest?

dajogejr Posted March 13, 2007 Report Share Posted March 13, 2007 If 155 was too rich, go 150. Do a proper plug chop to dial in your main. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted March 13, 2007 Report Share Posted March 13, 2007 ummm, 145 sounds way too low to me. ive always run 158 to 162 main jet in all pwk carbs. i usually run 42 to 48 pilot and settle at a 45. i really think you need to go up on that main jet. better be safe that sorry. at least if you try a 160 and it way rich, you might just foul some plugs rather than burn up a top end... if all else fails, see what jeff recommends. i bet it wont be a 145 main tho!

Banchetta Posted March 13, 2007 Report Share Posted March 13, 2007 Like loco said, something doesn't sound right. I know 5 other guys that have 4mils from different builders and we are all running around 162 mains....We are all at sea level as well. What is your elevation? Air box mods??

docbones Posted March 16, 2007 Report Share Posted March 16, 2007 I have a Cheetah 4 mil 421 powervalve, no airbox just k&n clamp ons and CPI pipes, 7 degrees timing. Trinity says start with 150 mains and 52 pilots CEL needles in middle. However, they said it may end up with 148 mains and 48 pilots.

Yep, I agree. Jeff helped me dial in my woods port over the phone and we got it almost perfect from the get-go! One or two minor changes due to temp, alt, etc, and it was F.A.S.T. :biggrin: Quote Link to comment Share on other sites More sharing options...
nicktoney Posted March 22, 2007 Author Report Share Posted March 22, 2007 well i decided to go do a jetting run and plug chop... i have 45 pilots and 170 mains (i know thats a rich main, but it was like 40degrees or so and i wanted to be safe... let me say, this bike HAULS! heres a pic of my plug chop... from what i see, its a bit rich.. also, as i pulled in the driveway, i noticed my banshee not shifting in or out of gear... i put it in the barn... all but 3 of my side case screws backed out and puked gear oil. i guess that will teach me to not put blue loctite on them after i painted my case cover. :shoothead: oh well.. anyone know where i can get some of these screws real quick?

jbooker82 Posted March 22, 2007 Report Share Posted March 22, 2007 So did it run better with the 155 main or 170 main? Just wondering if the 155 main spudder was lean or rich? Quote Link to comment Share on other sites More sharing options...
nicktoney Posted March 22, 2007 Author Report Share Posted March 22, 2007 well, im just a jackass is what the deal was... i thought i put the 155's in, but it was just the 170... and the sputter must have been shit gas because i put fresh stuff in and it went away completely...
