Came in to let it cool down, came back out 30 minutes later with the intention of going out, it started first time, didn't sound rough at all, then I realized the clutch was buggered, so I turned it off, followed the clutch cable, and tried to find anything significant. Then, I went to start it again but there was no compression with the kickstart, and I obviously couldn't bumpstart it.

srob said: All points towards clutch to me  If the internals of the engine are fine then yep. Seems odd for the clutch to just give up though, especially on such a small engine. If it's definitely spinning over when kicked then my money is on a detonated piston.

See from that I'd say clutch too, but why on earth would it not kick over in neutral with the clutch fully engaged? I say this because you've already stated it has to be engaged to kick over so it shouldn't be a problem if the cable is fooked or not, it should still fire in neutral.

Put the bike in gear, pull in the clutch and kick it over. It shouldn't move!

That'd make sense. Liam is the clutch arm forward, as if it looks like it's been pulled in and not returned? Not relevant to your bike but look here http://www.hondatwins.net/forum/viewtopic.php?f=51...Possibility it's gunked up and stuck, that would explain the instant free play and lack of compression as the clutch will be stuck disengaged.

He mentioned that the bike tried to pull even with the clutch in, which means it's dragging. If you kick it over in gear and it lunges, that would confirm it. If the kicktart won't turn the engine it could well be slipping.
Just suggesting things to try, don't even know what the bike is really and can't watch the video at work!!

LiamB said: Was trying this yesterday. I put it in gear, but I could still push it with only little resistance. What gear did you have it in at the time? It does sound to me like the clutch is stuck (maybe lunched itself slightly) with something stopping it from fully disengaging. See what difference it makes-even try a push in 1st gear-then 3rd/4th. If you can push it easily in 1st then it suggests the clutch is partly disengaged. The video does seem to show insufficient movement at the actuating arm. p.s. MAKE sure ignition is off before you push it !! Don't want to hear you been dragged down the road by an unexpectedly starting bike

I thought we had a snapped clutch cable but engaged clutch which would point to a compression issue, but if the clutch arm moves slightly it's got to be that the cable is fine and the engine is fine but the clutch is stuck open. Take the cover off the front sprocket, I bet it's minging in there.

Right, I'm in the garden now sweating it up.
The bike pushes in first, and has abit of resistance in the other gears but not much.
Any suggestions for what to do?

Also forgot to add that the bike lurches forwards when I try kick it in gear. So there is sign of life.

(i think we may be getting somewhere) If you look at the vid the cable only moves the arm slightly so it's pretty much all the way disengaged, must just be a little movement left to allow the clutch to slip. Cover off, check to see why it's stuck

Yep- I made that point above. It sounds to me as though his interpretation of "there is sign of life" is nothing more than the bike being driven forwards by the kick start whilst in gear. Clearly not actually starting.
Like you say a bit of spannering required.
Who is it that's only 2 miles away -Lord Flathead ? Sounds like a good offer of assistance to me.

Sorry guys, ran out of time.
Now off up to Milton Keynes to see my mum for 4 days.
