Bill,
Since I didn't notice if anyone else answered you on the gearing change
required, I'll give you some numbers.
17.75" tall tires and 8400 rpm (Kaw?) and current 5.38 chain ratio should
get you to 110 MPH-if you can actually achieve full overdrive in the CVT.
Lets assume that you aren't getting to 0.75 in the CVT and have more like
0.9...thats 91 MPH.
To get to 100 Mph you wouldneed to change to about a 4.9 final drive.
To get to 104 Mph, you need about a 4.7.
Alternatively, someone may have ideas on how to get the CVT to shift out
fully.
My guess is that you are bulding too much sheeve tension near top end from
too steep a helix or too high rate a spring.
The primary weights may not be correct for the pipes either and you just may
not be making any HP to pull the secondary open.
I'd work on that stuff rather than changing final drive if the 5.38 works
everywhere else.

I topped out in gearing at an autocross the other day with my 5.58 ratio
final drive gearing. What ratio would I need to gain another 5mph in top
speed? I bet there is an internet site that would answer that for me. A
125 shifter cart clocked 104 mph at this event!!!!!
