28 PWK

[dirtclod20]

My mods are in my signature, I have bored 28pwk's with 48 pilot 0.75 turns out, 160 main, JJH needle in middle. Bike starts, idles great, and pulls hard, however I believe it may want more main jet. My pods were pretty moist with oil when i started tuning, and after riding I think the filters are flowing better now making a lean mixture only at WOT for extended runs. To the point, where I'd just rather let off the throttle and let it run on the needle because if feels like it pulls harder. I have 1 162, 1 165, 2 170 main jets, I could throw the 170's in because they are available. No one seems to run over 160's with these carbs though, and my setup isn't any different then the next guys. Should I try a 50 pilot, drop clip on needle again, run 170's, all of the above or some of the above before ordering more jets? This is the last step of tuning before this banshee goes out Raptor hunting because of trash talkers in my town! Nothing much to prove, just 350cc's is better than 700cc, and banshees have solid steering stems from the factory! :-) Thanks for the help.

really need to know what kind of porting and what elevation to say for sure. but to me it would seem that 160 is actually a bit too much. i have stock stroke dune port and 28 pwk bored to 30 with k and n pods and im running 155 mains and they are nice and brown. id hate to steer you in the wrong direction especially if its too lean but that is my opinioin

I have a trail port, around 800' elevation. I plan on getting some new plugs and trying a plug chop, perhaps I'm closer than I think or too far? Thanks.
