when i roll on the throttle it takes longer than usual to catch, is there any way to tighten it or how do you fix it?

 

Yeah but there is supposed to be some free play there. I think 3/8 of an inch max. On the throttle theisan adjusternut an 8mm and a lock nut 10 mm. Loosen the lock nut and use the adjuster to give some tension. Give it a quarter turn and check the play. Keep doing it till you got it with in spec. It should be in your owners manuel. Don't forget to retighten the lock nut.

 

If you take all the slack out of the throttle, the RPM's will increase when you turn the bars to the left...that's why it needs free-play.
