just get 20'' tires it will help your acceleration alot to crank up the hills

 

if you have the stock spring then definetly get another spring. i hear pink is awesome for the stock v. you'll really feel the difference.

 

To answer your question on the big bore kit, I went with Four Stroke Tech's 785 kit for my V. It has performed perfectly for me. Mods are in my sig.

 

also were can i get a pink spring are they hard to change i am pretty mechanically inclined thanks for the help.

Primary springs are a piece of cake to change out.
