I have a stock 02 Viper 700, I would like to make it get up to speed faster. Can I drop 2 teeth on the top and use the stock chain? Also what is the biggest riser I can put on without cable extensions? And where can buy these parts from? Thanks.

do you not care about loosing top speed? cause you will lose approx 10mph w/2 teeth down on top. also, you don't have to gear down to accelerate quicker. you can have steeper angled helixs and aggressive weights, to get the clutches to shift quicker. but, judging by your cable extension statement, i am assuming you ride in the powder in the back country? if so, then you will need some shallow angled helixs. the steep angled ones will upshift you too quickly in the powder, and you will overshift.
with a viper you already have a 68 link chain, so you can drop a tooth on top and gain low/mid range with the sacrifice of topend speed. You can reuse your stock 68 link chain. The viper has 22/38 stock which is 1.72 ratio, by dropping to a 21/38 youll be at 1.8, that a fairly large jump. For your riser question, its in the FAQ section on site.
I just installed the powermadd pivit riser with a 2 inch block for a total of 3.5 inches on my 04 and it work without changing anything. I also dropped the top gear to 21 made a world of difference.

I am looking at the gears at denniskirk, but I don't know what spline or plate width I need.
Also, Is the pivot riser alot better than just a block?

Just give Port Yamaha a call for the gear. They are a site sponsor and will know just what you need.
