Hi there
I understand this forum has a lot of info about how to get a Yamaha Banshee a lot better but everyone has their own setup so it's always different.

I want to get it strong all around power. Of course it has a peaky power but i want to attenuate that somehow.

Engine mods i have already installed:
FMF Fatty + Power Core2
Keihin PWK 28mm

What should i get to improve all rpm ranges? i was thinking about Dynatek FS CDI for example...?

Thanks

Adjustable stator plate. Set it to +4 timing. That helps out all across the board, but mainly down low.

boyessen rad valve. it will help with the weak bottom power of the shee. it will smooth out some of that wicked mid range hit. it helped when i had mine.

Your in the right direction by wanting a reed valve but the boyesen reed valves have been known to actualy decrease power for some reason.

If you want good all around power those fmfs and keihns should give you the mid and topend pretty good. So to cover some more bottem end bump up your compression I vote for some type of cool head theyre just a good mod IMO, Adjustable timing plate like dmc stated, Good filters, You could buy some ported cages I've seen them on ebay they're a cheap alternative to different cages and are a fraction of a cost. If your still looking for a little sumthin sumthin the best thing you could do is port your cylinders for wherever your lacking. Thats where the real #s are at. :cool:

CDI's don't really do much at all...

You might want to look into a cool head. Not only will it run cooler, but you can run 21cc domes to bump up the compression which helps all the way across the board.

Gonna have to go with DMC on that one. I have a pro design cool head on mine and have no complaints.
