I'm a beginner mechanic so what are some easy modifications I can do to my warrior without paying a lot of money.

 

add a pipe and get a prodesign air filter with k&n and rejet the carb

 

How do I jet the carb?

 

your pilot jet does idle to 1/4 jet needle does 1/4 to 3/4 and main jet does top end of throttle go up on main about 2 or 3 then back down untill throttle is chrisp last check spark plug atfull throttle and shut engine off and coast in and check it
i forgot if it backfires it is lean and if it is lean dont ride it even if you think its fine you must check spark plug
the main and pilot are in the float bowl and the needle is at the end of the throttle cable

 

the whole idea is to get the air in and out of the engine as soon as possible anytime you modify a engine you must check jetting

 

Could you recommend a pipe/s.a. to us? I would like to start here and make more "improvements(?)" later. Is it best to go ahead and get the head pipe too right now, or wait till the engine needs it? Thanks!
