Banshee has no powerband! Help!

Recommended Posts

Hey guys I have recently came across a problem with my banshee after my pops and I put it back together. We have done a complete rebuild top to bottom this winter and when we started it up recently it doesnt seem to hit the power band. It makes a lot of noise, but doesnt go anywhere.


Upgrades are as follows:


Toomy T5 pipes

Cool head with 21cc domes (new domes)

Pwk 28s with 158 mains (new)

V force 4 reeds

Vitos trued and welded crank (New)

Uni pod foam filters

Port job

65mm pistons (new)


All electrical components are factory oem, but have not been replaced as far as I know.


I am at sea level: Hampton Roads, Virginia


The banshee starts first kick and idles great.  I just dont know what could be causing this issue. Mostly everything is brand new.


Reeds have checked out fine.


All help is appreciated!


Help get me riding this summer!

What do you mean by it makes a lot of noise but doesn't go any where? Are you saying the motor revs out but the quad doesn't move or that the motor doesn't rev out

I was saying it to be funny. It goes through all gears fine. The tors system has been deleted and rev limited is disconnected.

Ok. Have you checked the clutch? Maybe it's slipping?

What do your plugs look like?

Havent looked into the clutch.


I just jumped the carb jets up to the 158 mains to richen it up because I thought it was too lean myself. Now they have cardboard color look.

Does it run better with the bigger mains?

What size pilots do you have?

Yes it seemed to clear up a little more. It was backfiring and making a poofing noise before I ordered the carbs. Have to check on the pilot sizes and get back to you. I ordered the pwks from carb parts warehouse and they put them together based on my mods.
