Anyone change out the front sprocket on there bike? If so did it make a good difference?

 

I've got a 13-tooth on right now. I ran both the 13 and 14 back-to-back yesterday paying very close attention to performance while hillshooting. The 13 won hands down. Now for anything other than hill shooting, I'll keep the 14 on. With my mods, the 14 provides all the bottom end I'll need for trails, track, etc. and keeps the bike significantly faster The 13 makes the front end come up like a Raptor.

Takes about 10 minutes to swap out.

Has someone tried yet the 15 teeth sprocket in front for the YFZ450. I would like to buy one for riding fast tracks and hardpack (we can ride on roads here). Does a 15 teeth fit ?
