I have a Throttlemeister on my Firebolt, and 95+ heater kit waiting to fit. I Emailed Throttlemeister on
cruising@throttlemeister.com to ask if a 95+ was compatible.
The reply from Throttlemeister for the 95+ was:
"
It should work fine with those as long as you install the friction sleeve from our kit over the throttle tube before you glue the grip down"
I have seen posts where riders claim that Throttlemeister will supply a modified friction sleeve for some types of heaters, so its best to check.
