Gearing out of Whack

I have an 04 yz450 with the gearing 13/52. I am unable to use first gear for almost anything but with the rekluse I get perfect 2nd gear starts. I was wondering what should I change the front sprocket to get top speed around 100mph.

13/52??? Surprised you even use 2nd gear! To get 100mph you will need around 15/40 approx. Tdub

I'm looking to have more top end than the stock originaly had but I am wanting to use the 52 rear sprocket. What size front sprocket would be best for more trail riding than motocross?

13/52 is way radical for an 04. I will bet that thing is like riding a jack rabit bouncing off of the rev limiter. 100mph, you will have to gear that thing like you are racing the world's fastest Indian (the movie) :thumbsup: .
