Specs on the cat page are wrong. 24/50 is the 141 inch version. 21/41 is apparently correct. The Yamaha version will have overdrive more comparable to a doo at close to .85 apparently. Should net 120s.

Jester nice to see you over on the dark side but the new clutches are .91 overdrive up from there .93 not .85
21/41 will net you 123 at 9150 rev limiter unless yamaha has raised it.

Jester this is funny you mentioned this speed vrs rpm,because keith woods who was in there testing at the airport runway they were testing was saying it was not set up perfect,and neither was the apex it was running against,he said the ape was running 9800 and the sidewinder was way overreving past 8700 so maybe that is why it was turning 123 gps.Jester nice to see you over on the dark side but the new clutches are .91 overdrive up from there .93 not .85
