I'd known this engine was based on the K5-8 which has a hydraulic clutch, but hadn't really taken too close a look at ours. The other day, I decided to get in and clean the front sproket while I had the rear wheel off and plenty of chain slack. Noticed something I hadn't really bothered to think about: our clutch actuator is on the left side. Took off the sproket cover, and sure enough, a clutch pushrod. So, we're basically already set up for hydraulic. Has anyone looked at swapping a K5-8 system over? If I can find one on eBay cheap enough, and if no one has already ruled it out, I'll take a look at compatibility.
