Yea the 65 rips, I let a dude who has a revo ride it and he was like, damn that is scary. The Parmakit is super lame, don't waste your money. I saw that there's some autisa kits floating around too. Kstar is super easy to make work, or tccd 50 would be pretty cool too!
One way is super duper easy to start. I think with the one way I wouldnt have had as much trouble starting the euro kit, fighting the starter clutches to get a full engagement was harder than cranking the motor over.
The one way bearing is most certainly not going to hold up great for daily riding. It took just over 10 minutes of straight idling, albeit without enough grease, to blow it up. This time around I completely filled the whole inside of the clutch bell with lithium grease. We will see how long it lasts.
I mean doppler clutch pulleys do fine with the one way bearing set up.
