I recently purchased a 2002 Banshee. Its mostly stock other than the FMF Gnarly pipes, K&N, Boost Bottle. The bike starts right up and has nice midrange power but when you open her up and go through the gears it seems like the top end power just flat lines. Its not bogging or cutting out but the power just drops off. Ive checked the plugs and they are dry and brownish in color. Ive checked the compression and its right around 120psi on each cyl.

 

Ive read that the Gnarly pipes are for low end power and was wondering if the DMC Aliens would help me out here. My buddy had an 01 shee with a DMC 916 system and cool head w/20 or 21cc domes and it was pretty hard to keep the front tires on the ground through the first few gears. To bad it was stolen. More than likely by someone who is on this site. Anyway...

 

So far I have installed a Noss Machine head w/21cc domes. Just wondering if I should keep the FMF pipes or go with the DMC's?

What carbs are you running? What jets do you have in it? Gnarlys are a low end pipe, sure your bud didn't have more than just pipes on it? Such as porting? Might also try +4 on timing.

 

BTW, Welcome to BHQ !! :cheers:

 

OOps, just noticed, mostly stock = stock carbs :jesterlaugh:

Just tore into the carbs and it has 240 main jets. Needle is on 3rd groove. Dunno about the pilot yet. Ya stock carbs! Im in MO so about 700-900 ft. above sea level.

 

Ya im sure my buddy wouldnt lie to me about mods. He always talked about doing more mods like porting,ect.

 

Thanks for the welcome!

Oof, thats probably the best way to jump onto a forum, calling the members on it thieves.

What do your plugs look like or have you done a plug chop? Try running in 6th WO and pull choke halfway out , if it improves your'e lean.

Reason I think you may be lean, my son's shee is unported 4mill , FMF Gold pipes, K&N, no lid, 310 main,27.5 pilot. Being that it has 2mil head spacer rather than cyl spacer basically it's de-ported. :cheers:
