How often to you Hit top speed 112 + mph. Lots of lake runs???
You can change your own clutch or gearing to gain more on top end.
Do a search on here or the web you'll find alot of useful info on the srx

They've must of machined the primary to get the over drive. wich means they've machined the primary sheaves to get the belt in a higher drive ratio.
