I'm bought some toomeys from a buddy perfect shape for $150.00. But no jet kit. Do i absolutely need to re-jet? How important is jetting it? And if i do whats the best jets to go with. Stock Banshee with boyseen reeds and k&n filters. Whats jets would you go with?

 

310 or 320 mains are probably close for T5's , I believe stock is 200 or 220's, which is gonna be on the lean side

 

definetly jet.

i dont know wat jets. i dont think it matters.

You have a two stroke now. If its too lean it will burn up almost instantly or slowly damage itself depending on how lean. If its too rich then it will be weak and foul plugs. So when your jetting you start off way too rich and slowly back it down until its right.

 

definetly rejet or you will blow your shee upp or cause it to wear out way faster plus rejeting will add power to get full use out of the pipes

 

You must rejet. you will need to change the pilot jet (35) if i rember right, I would go with someones needle (I have vito's) and i also run 330 main jets.

 

depending on your altitude, set your mains between 280 to 310, set your pilot jet at 27.5, set your needle in 3rd clip, and air screws back out from about 1 1/2 turns. if u dont rejet, u will run lean, overheat and destroy your motor. just my opinion.
