i wanted to get new sprockets -1 and +2 because theres really no need to go 100+ on streets. whats a good website to get these from and whats a good brand? also if i get both rear and front sprockets, will i have to get a bigger chain?(i have a stock chain now) i know that when you change the sprockets it messes up your mph and mileage..anyway to fix that so its back to normal when i switch them?

 

VORTEX makes nice stuff. not sure what i have tho. you need a 520 chain and a speedohealer will fix that speedometer up

search speedohealer

heres a site, not sure if it has the stuff but its got lots of goodies, so check
