Default Re: Sportworks 650 UTV engine swap project

Just to share, for anyone new to CVT driver/driven clutch setups, or anyone going through the daunting task of tuning the shift curve, factoring in a different powerband and "drivability profile", I found some good (FREE!) technical info here: https://web.wpi.edu/Pubs/E-project/A...ited_Jan19.pdf

A long read, but well worth it. Also Olav Aaen's Clutch Tuning Handbook has been VERY helpful for me as I am new to CVT transmissions. Not sure where to buy it but it can be found online in pdf format. Goes over all the details of the CVT and how to tune it. Mostly covers the P85 style clutches, but the theory applies to any Comet, Yamaha, Polaris, CVTech setup.
