bike broke down

[supermancss]

Was stuck in shaftsbury for 3 hours waiting for the AA on Sunday. I was riding along at 30 went to change gear just after accelerating. Didn't stick it up enough and went into neutral. Then got it in gear (no idea what gear). Rode along 15secs fine. Then clink clonk, back wheel locked a bit and back end skidded a bit. Pulled over and could hear metal flicking on metal. Figured chain was the problem.

Now my thundercat won't start unless I pull clutch in. If I try starting in neutral without pulling clutch in it jumps forwards as if its stuck in gear. I can't shift gears up to 2nd ot anything. Only down to first and neutral. When pushing the bike switched off the chain skips and flings about and sticks at certain points.

It passed its mot Friday with no advisories which is typical.. hope its not major broke i have no experience of clutches or gearboxes. All I'm able to do is have a look where the chain goes in towards the engine.

Just bought some new leathers which also takes the biscuit!

Anyone got any ideas or suggestions as to what I should be checking? Many thanks in advance

as for clutch is it adjusted at the lever correctly? maybe that its just slipping and why won't engage or start properly.

chain sounds like its loose and maybe popped off the front sprocket i'm no expert but thats what springs to mind for me.

where you based?

Bad news Ash, hope you get it sorted soon and it's not too expensive. Could be the chain or sproket, when did you last check your chain and was it ok?

I'm still learning my way around the bike mechanical side! I think the chain currently is too loose. It was in need of oiling begore it went in for mot. I think it could have been too loose then mixed with chain lube and popped off ?

I am in Trowbridge. Got Wednesday off so will give it a good look over and do a visual inspection. Fingers crossed it'll be somthing simples! Keep you posted once I've opened her up !

If your chain was loose enough to jump off the sprocket it wouldn't have passed the MoT. This sounds more like a gearbox issue to be honest if it's stuck in gear. Best of luck with it but a bit of specialist help may be required. :-/

Sounds like a bent selector fork to me, but before going down that line, check the primary drive and clutch.

It's not a Brit bike Jon, primary drive is directly geared from crank to outer clutch basket. :
The clutch sounds OK if it won't start without it being pulled in. Agree on the possible bent selector fork if it was kicked into gear with the engine under load after hitting the false neutral. Probably an engine out and split the cases job, I'm not aware of the ThunderCat being reknowned for in-situ gear selector access...

I know that!!!! :

Could still have damaged the gearing, bearing or clutch or clutch actuator.

Gutted really, will take it apart a bit and check the easy bits.

Ive just bought some new leathers, had it MOT and front fork seals done. Tax is due end of this month.

cost of recovery.

Spent nearly £800 on biking related in a few days, very sad

Sure someone could lend a hand... If you ask nice enough
