What does a plug chop show?
The more specifics you can provide, the more we can help.
BTW, those 2" drags aren't doing you any favors. | |

| I am running a 70 main jet,and a 28 intermediate jet.Feeding the carb with a high flow Pingle.I was running a 2 into 1 header previously, with no baffle.Also the 2" pipes are not baffled. | |

| i would suggest to try to baffle the pipes........you are going to have a very difficult time tuning the carb with 2" open pipes.....unless you want to tune for top end only,full throttle and not rideability..........

| Well I guess 70/28 is a good starting point. I'll see what that does for me,If you have any more suggestions they are greatly appreciated.

| You'll most likely find you will need some back pressure on those 2" drags. Shovels don't like drags tht much and 2" drags even less. You are probably getting a ton of reversion and it is causing the midrange fouling. http://www.directparts.com/static/ar...reversion.html | |

| it shouldnt take much,,,,,just enough for some backpressure.....i have seen small baffles that slip into the end and are secured with a screw.....that should be enough
