If he's doing mostly street I'd say a better filter in a K&N would be better is all.

Some have also reported minimal gains by cutting the mesh. I personally kept it just in case something large happened to get under the filter.

 

admittedl. I am a little partial to sport bikes. I couldn't afford a new one and my dad wouldn't let me buy used because he doesn't trust a used bike.

Also, I don't care about doin a wheelie while I'm riding. I just want to be able to do it from a standstill. Stock with tbr exhaust, the wheel picks up maybe 3inches off the ground

 

Sorry I got side tracked... Anyways I would love to get a bore kit but I can't afford it. I figure jetting and airfilter as well as removing snorkle and maybe lid should get me what I want. If I change the front gear for more torque will I see any significant top end loss? Does anyone have an estimate of how much it costs to get a bike dyno tuned?

 

Oh also for street which air filter is better? k&n twin or uni

 

K&N ftw
