Runs great on flat but not on dunes


Recommended Posts

Hey guys, I have a problem with my banshee that runs great with no loose in power or bogging in flat dunes or pavement and pulls really good.


However, when I ride on the dunes and trying to get uphill starting from  the 1st gear to 2nd once I pull the 3rd or sometimes 2nd it looses all the power while im uphill and I need to downshift to 2nd and 1st for the banshee to hits its power. Sometimes it bogs when I downshift to the 1st and have to push the throttle really fast to have the power comes right to save me making the downhill hahaa.


If I want it to pull its hardest power, I have to ride a little distance before the hill and try to make it hit the powerbond 1st, 2nd and then to 3rd gear and it goes fine uphill (all with WOT) but as soon as I take the throttle little bit off nooo all power will be lost and need to downshift. 


I tried my friend banshee that has T5 and it pulls and make its power in 1 sec and he can upshift when he is riding uphill unhill the 3rd gear but mine upshift in that situation will make it loose the power I need to downshift to 1st or 2nd to wake it up.




Stock carbs and stock cylinder and piston (factory).

1 to 1 big K&N filter with factory airbox and lid.

Pro-circuit pipes.  

V4 Reeds

I have no idea about the size of jetting because the shop has put in all the mods.

Elev: 2000-2300 ft

Temp: 50-68 F

Your help and advice will be highly appreciated.

Pull off your carbs and clean everything real good, I think your floats are sticking. Reset your float height, buy carb kit and then let us know what jets you have. Have a look at your cylinder intake area and let us know if you see some porting.  You may need a jetting increase. Regardless, pull off carbs and clean them.
