I'd be more than a little shocked if you can buy a 'rebuild kit' for your engine. What you really need to do is open it up and find out what's going on. You may find something that can be relatively easily repaired and can assemble a short list of the needed parts. On the other hand, you may discover catastrophic internal trauma. Diagnose the specific problem first, then determine the strategy to resolve it. Don't dismiss the option of buying a used motor as well.



It would be a great idea to add your bike info to your signature.

When you say by hand do you mean with a ratchet on the crank shaft or spinning the wheel.



If you're talking about spinning the wheel I think the idiot that said that was possible and easy should be shot because it's a pain.

Could also be clutch problem or water (or other liquid)in cylinder(s)...did you try ratchet on crankshaft as BS suggested? Take plugs out, remove chain, check clutch then try ratchet to crankcase.

Good luck.

It may be financially prudent to source a running engine if the present engine is kaput and use the present engine as a donor.



However by re-building the engines from the crank up will give you a profound knowledge of the engines which are,IMHO,a superbly designed power-plant and not over complicated.There is also an intense satisfaction,that money cannot buy,in firing up a fully stripped and re-built engine and getting it right.There are also moments whilst riding a re-built engined bike where you feel,"At-One" with the machine having had the crank shaft in your hands.It's hard to explain,but it's there.



A lot of people over the years who had never touched the mechanics on a bike have learnt from this and other forums to do work they never imagined they could do and they too get a great feeling of satisfaction riding their bikes knowing they have done the work themselves.

They also free themselves from being held ransom by motorcycle shops that can charge the earth for work if they will even take it on on these old machines.



As for parts I think you will have to start searching as usually there's no one supplier,at least over here in the UK.



If you are stuck for parts and with the exchange rate in your favour you can get parts from the UK and Europe if need be,

All of the above have good reputations.

I actually have, here in KY, probably about 75% + of an '80 CX500c engine sitting at home. I would be more than willing to share the wealth!



Lancaster is a few hours away, but, hell - I just live about 5 second from the river south of Cincinnati.

As I decided these were the bikes for me this is basically what I have done over the years e.g have a running CX and then re-built spare engines as I went along making things better.I bought up some basket case engines off Ebay which have also given me my own,"Spares Depot" in my garage so I want for very little to keep my bikes on the road.

In the 1st 3 years of ownership I probably spent about say 1500+ beer tokens inc cost of the bike/s but for the past three or more years I've not spent much and have ended up with two good CXs and plenty of spares.





My best Ebay deal was two rough engines,a frame with wheels and title and a box full of bits nearly enough to make a 3rd CX which I may get round to some time all for 75 beer tokens.Just needs an engine building




PS

These engines are a joy to work on
