jetting or pingle valve?

[banshee35005]

i have mikuni 28mm flat slides ported to 30mm with fmf sst and clamp on k@ns and trail port i put carbs on same time i ported motor they have 330 mains in them and it runs great in 1st and 2nd and most of 3rdgear and half throttle but on longer pulls wide open i have to back out of the throttle or it bogs down and feels like im loosing fuel i think its jetting i dont think im pulling enough fuel to empty the carb bowls or that i need a dual pingle valve??? / anyone running same setup main needle size???

i had the same issue with a cub setup and i ordered a pingel..while tahing the old fuel valve out i found a pile of sand and other stuff blocking the filter in the tank..that being said i would first chack the filter inside the tank...might b an easy fix?

I'm running a pingle with a stock carbs and 320 mains...so far bike runs really well

I dont think fuel supply is your problem and a pingel probably wont help.. I'd check your float settings and make sure your needle and seat is clean.

Make sure the vent on your Gas tank cap is good.... Make sure you can blow thru it easily..... If not, you need to take it off and

 

gut the internals..... I was having the same issues last year on a ported stock crank, cylinder banshee..... and i was running the dual

 

pingel... It was sorta causing a vacuum lock, and 3to 4th gear pull, i was sucking my bowls dry, with 34mm carbs...... Also, make

 

sure your fuel feed lines are in good shape, no extreme kinks or bends, and that they are routed good..... And if your making decent

 

power, you should put the dual pingel on your set up.....

i just put in some 400 main jets on the mikuni 28 flat slides and running almost perfect now but still feels like 6th gear dont pull quite as hard as it should maybe i need new k&N clamp ons the old ones are well used and looking pretty beat or maybe 410-420 main jets

haha, jetting was the first thing i was gonna suggest. yah, you should be within 1 size by now, if it is just 6th, and 5th is pullin good.......probably do a plug chop once it pulls fine, just to be sure
