I ride the local river in the winter and am thinking of 17/36 gearing what do you guys think top speed will be with 20" tires. My friend rides a yfz450 and i would like to stay with him this year.
 
I ran a 14 front 38 rear on my 87 with 22" mud lites. It lost some low end but was really fast top speed. Made flying throw feilds a blast.
 
15/38 is the fastest I have found on my 350. 15/36 slows it down more because it doesn't have the power to pull the gearing.
 
My quad? Uncorked the pipe, modded airbox lid, and ported head.
