Hi guys, a couple of replies to Mr Honda Hawaii and Tim Allman. First Mr Honda, I did exactly that, I flipped the engine and removed the bottom end, withdrew the crank partially and rested it on some wood. Getting the cam chain sprocket off was a challenge but eventually it released its grip. I fitt...

The little Honda is back together, I did a rough guess as to correctly locating the cam gear. I looked at a few pictures of the type that has the locating key way and the timing mark appeared to go to the bottom position with the crank at tdc. I put the gear in the oven for about fifteen minutes and...

I’ve managed, with a struggle,to remove the crank bearing, it was definitely loose on the crank. The new bearing is a much better fit so I’m confident that a smear of Loctite bearing fit will cure the problem.

I’m hoping to park a couple of my bikes in a friends garage next week so then I’ll I drop the engine out and have a look inside. I’m not aware of any differences in bearing size, I’ve just o...

Thanks Michael, At the moment I’ve not got room in my workshop to drop the engine and strip it completely but as soon as space is available I’ll start the autopsy. My only thought currently is did the bearing partially seize and spin on the shaft, when I bought the bike it had been off the road sinc...

I decided to double check the bearing number so partially stripped the generator side of the engine. I was surprised to find that the bearing appears to have no play in it but the crank is rattling around in the bearing. I’m not sure if this site will support a short video clip but I’ll try. If not ...
