300ex gear ratio

[Quinton Turner]

Iwas wonderin whats the best gear ratio for a 300ex. I want to have a little more kick in top speed but still be able to pull wheelies. I have 20in Holeshots full big gun race series jet kit and k&n air filter.

You basically have 2 choices:get a 14T front sprocket or get a smaller rear sprocket(1-2 teeth smaller)

BUT if you use the 14T sprocket then you either have to remove your case saver or grind it down to almost nothing. I prefer changing the rear sprocket just because it allows you to keep the case saver even though it will be much more expensive. In the long run the rear sprocket is still cheaper than a busted engine side case though.

I have 13/26 with 20" rears and it is perfect. I just had to put a halflink in my chain.

13/26:huh . Don't you mean 13/36? I don't think I have ever seen a 26 tooth sprocket.
