Got this from thatsdax.com (never should have done that.) Anyway, it's been a long time getting this together. Thought I'd upgrade my 2stroke to a 4 stroke. Well today I put in oil and fuel, fired it up, but this thing could't pull the bike by itself let alone with me on it. Just no power what so ever. I thought a video might help, you can hear the motor and see how as soon as I set the tire down it just stops turning. Anyone have a clue what the problem is here? I sure don't. Very frustrated now. Here.
