jsaylor Posted May 11, 2016 Report Posted May 11, 2016 Hey everyone, I just got my bike rebuilt and went to a ported 4 mil. The problem is I can't get the jetting lined out. Any help will be appreciated. This is what I got and where I'm at. After several tries I got the idle and 1/4-3/4 throttle good. It's wot that I'm having the problem with. When I'm cruising along and hammer the throttle it's like there a big lag. Like the bike doesn't build speed or rpm. Then when it finally pulls powerband it's starts to sputter then clears up. I just dropped down from a 320 main to a 310. Noth much difference. I'm afraid to go lower without someone opinion. 1200 asl .20 over 4 mil with agrees ice trail port uni pod stock carbs v force 4 reeds fmf fattys. Any help appreciated!!! Quote
Surfrjag Posted May 11, 2016 Report Posted May 11, 2016 Is your stator or cdi or flywheel aftermarket? Is the pickup gap set at .020"? Did you test for air leaks? Quote
jsaylor Posted May 11, 2016 Author Report Posted May 11, 2016 Cases held 6 pound for over 2 hours. The stator is aftermarket. Haven't checked the pickup coil. Can the pickup case similar problems? Quote
Surfrjag Posted May 11, 2016 Report Posted May 11, 2016 Get an oem stator. Ill bet you thats the problem! 1 Quote
jsaylor Posted May 11, 2016 Author Report Posted May 11, 2016 It's a Ricky stator. I should of done some research before I bought it. U don't think jetting is the issue? Sent from my SM-S902L using Tapatalk Quote

Sent from my SM-S902L using Tapatalk yes you should have. Could be, but 99.9% of the time those stators cause the issue your talking about Quote
Surfrjag Posted May 11, 2016 Report Posted May 11, 2016 I had same problem with an aftermarket stator so.... no Quote
jsaylor Posted May 11, 2016 Author Report Posted May 11, 2016 Okay thanks alot guys. I'll be looking for a oem stator. Sent from my SM-S902L using Tapatalk Quote
sleeper06 Posted May 11, 2016 Report Posted May 11, 2016 Put a 360 main in it , 30 pilot, toomey needle 4 th clip. Sounds lean to me. All my aggressive 4 mills jet no lower than a 340 so start a lil higher and read plugs Quote
jsaylor Posted May 11, 2016 Author Report Posted May 11, 2016 Okay I'll give it a try Sent from my SM-S902L using Tapatalk Quote
sleeper06 Posted May 11, 2016 Report Posted May 11, 2016 I have also seen stator a cause similar symptoms , but I also think your jetting is off Quote
Surfrjag Posted May 11, 2016 Report Posted May 11, 2016 Please tell me you dont have stock pilot jets in it. Even the vf4 box says to up them... Quote
Surfrjag Posted May 11, 2016 Report Posted May 11, 2016 Jetting def needs to be addressed but that stator needs to go first. Guess i should have worded it better. Quote
