Hello,
I recently bought a 2013 C650GT with 48K miles. The price was good, so I thought, why not. It seems to run well but seems to require a lot of revs for speed and acceleration. I had seen mention of people modifying the variator and roller weights and how that affects the acceleration and effective gear ratio. As a test, I took it up to maximum speed a couple of times and see that I hit the rev limiter at 97 indicated consistently. The tach bounces at that point off the last bar. Acceleration is linear and I don't sense any slipping. It has very strong acceleration from around 40 to the rev limiter.
Do you think there is a good chance that the roller weights were changed to be very low and that's why my top speed is so limited? 97 indicated is probably more like 93 or 94 mph. It really accelerates hard, but then again, I've never ridden another C650GT to benchmark it. I absolutely love this thing. Coming from an R1200GS LC and Tiger 1050, both I still own, I feel in the tight stuff, I can ride this scooter just as fast despite having far less power.
I have ordered the parts I need for a belt change (including the special tool to lock in place) as I have no idea on the health of the CVT belt. At that point I'll have a look at the roller weights and CVT assembly.
