I have built 2 Motored bikes before, my latest is a slant head 66cc grubee skyhawk($160)on a single speed Schwinn and costing about $6oo all told. A big chunk of that cost was $110 dollars for Spooky Tooth's HD wheel. Since reviews for this thing seem few and far between I figured my info would be useful.
The HD wheel seems nice and sturdy, and I like that the Hub kit doesn't mount the sprocket through the spokes. I had it on my bike for a couple of days w/o the engine on and it sure seems beefy. However, upon installing the kit and having the drive sprocket linked to the engine i found problems.
The clutch on my engine was on a little tight and didn't seem to disengage no matter how tight I adjusted it w/ the cable, so I Loosened the star nut on it and fixed my issue. But while I was trying to get my alignment right I noticed that the drive sprocket was threading off the hub allowing the wheel to turn and the bike to move with the clutch engaged. I rolled the bike backward and It seemed to snug right up.
Once I had the clutch disengaging like it should I went out for a quick start-up run, after afew tries and a few adjustments, I was turning the engine over, but I never really got the thing started. After throwing the cluch 3-4 times I noticed that I was free wheeling and that the clutch had no effect. I looked closely at my HD wheel and tried to hold the sprocket while spinning the rest of the wheel to tighten it up, since the sprocket mount seemed to have come loose on it's threads again. The sprocket was spinning free, and would not thread onto the hub.
I removed the wheel from the bike and after removing the brake I can see the problem more clearly. I am slipping the sprocket and bracket in and out over the threads with little resistance, and can spin it freely w/o grabbing any threads. I got stuck in getting the inner 'drum' portion of the strap brake off the axle, the thing is really snug.
Roland @ Spooky Tooth agreed to replace/fix this once i get the drum off and get a closer look @ the threads. So far, despite my initial satisfaction with it's beefyness, my overall HD Wheel experience has been rather dissapointing, especially considering the cost.
Update: attatched pics of hub and sprocket bracket mailed to spooky after I removed the brake drum
