Honda CB 250 RS project kick start clutch lock problem
Laverda Dave:
Have you had the engine completely apart at all? Has the bike been running normally and did the Kickstarter problem just happen out of the blue or has there been other symptoms leading up to this problem?
Laverda Dave:
Ok, so reading the first post again you say you've had the engine apart. When you reassembled it did you ensure the two alignment marks on the Kickstarter shaft were aligned. There is one on the ratchet and one on the shaft, if they are not aligned it will lock up. These two dots are in addition to the two dots on the decompressor cam I mentioned in my earlier post.
Laverda Dave:
If you are not sure the only way to tell is to split the crankcase as these two alignment marks sit on the Kickstarter shaft that is inside the crankcase.

Thanks for the reply.
I am beginning to suspect the lock up is occuring in the gearbox somewhere this will invlolve a complete strip down of the engine again.
I did rebuild the crankcase/gearbox.
Just seems so bizzare though that the engine "will" change gear when turning which tends ot suggest it's not the gearbox.
The clutch turns with the engine as well.
Also it still locks up with no plates in the basket.
It is not on the crank side either the valves are lifting and closing correctly on TDC the cam chain is not stuck it turns over smoothly.
Just cannot figure out what this is.
Rebuilt quite a few engines and never ever had this issue before.
I'll go for the complete strip down that's the only way I would find anything wrong I think.
The only possibility I can think of is there's a woodruff key stripped on a gear wheel and it's spinning or jammed somewhere on the shaft that holds the clutch that's the only possible thing I can think of.

Yes agreed I'm sure all the shaft dots were aligned correcty.
I am going to have to strip it all down again I think only way to check things here.
Thanks for the replies.
