I have the skyhawk grubee 4G engine kit that came with the HS 142-f tapered shaft engine. The first clutch somehow got completely worn to the point I was riding metal to metal on the way back home. This is only after 50miles so far. I got a replacement clutch and notice it has already started slipping. I will open up the transmission tomorrow to see what it looks like inside, but I have a feeling the clutch is burned. I do notice that with the original clutch, the tire spins at idle when I pick up the rear of the bike. The cable and throttle trim are adjusted correctly so that the throttle goes all the way back to idle position.
As for the tapered shaft on my engine, how do I know I have put the clutch far enough on the shaft so it doesn't slip between clutch and shaft? I know the tapered shaft isn't keyed and work strictly by press fit friction. When installing the new clutch pack, I just used a deep socket and dead blow hammer to drive it back on the shaft. But I have no clue if I have driven it in far enough or tight enough so that it is not slipping. I did notice toward the end of my ride today with the new clutch, climbing up the hill towards my house, the speed dropped and the engine started revving higher gradually, a sure sign that something is slipping. Now I wonder if there is any possibility that the clutch is slipping on the shaft? Would there be a way to tell?
