Another bikes battery using jump cables on the starter, this is how I got a slight turn out of the engine last night.

The battery is completely fudged, this is a fact. Does this stop the coils doing their job?

I thought the engine wouldnt even spin, that needs sorting before you worry about ignition. The engine should spin over no problem without any coils at all but obviously wouldnt fire into life.

If there is mechanical resistance to the engine even turning then you need to be careful using the starter until you figure out what it is.

I wonder if the second battery is weak or the jump leads have a poor connection resulting in not much umph to turn the engine properly. I cant remember but does it spin properly by turning a socket on teh end of the crank? If it does then a healthy battery should spin it no bother, I would use a car battery instead if you have one, loads more cranking power.

Ahh well it spun for like maybe one turn then seemed to get stuck at the starter again...

Basic order of business

Does the motor turn freely (by hand) = No (make sure it's not in gear)
Remove Plugs, does it turn now = No
Remove start motor, turn now? = No
Remove cams, does it move now? = No (check valves)
Remove Head , turns now? = No (and check pistons and bores)
Remove engine side casings,turns now? = No (visualise transfer gearing)
remove clutch plates from basket, turns now? = No
split engine and examin crank/rods and mains.

Cheers Mark

this was a working motor until it got transported wasnt it?

Thanks Mark

Not something I thought I'd be doing with the new motor

Yeah, which is why just looking at what Mark has said, there could be a prob with the way the clutch plates & basket were sat in the car.

I keep coming back to this thread to see how you are getting on & I am totally gobsmacked that it hasn't been a straight forward thing.
I would still say that oil is somewhere it shouldn't be, other than the misfire which I thought was the coils or carbs, the motor was fine. I would run with Rictus' ideas.
I certainly wouldn't try to turn the motor over with a battery. I did that once with a Moto Guzzi & ended up smashing a piston, use a ratchet on the end of the crank, as Mark says it should turn over by hand quite easily

Col, you didnt sell him that one we found on the scrappy did you with the bullet holes in it?

Sounds like something has fallen out of place in transporting it.

Right, last night, took the clutch bits out as have to if the casings come apart. Nothing to do with round that area that is smacking me in the face.

My mate that came round to help me have a look seems to think that it could be the valves, as it seems to make one revolution then get completely rammed stuck, when I told him that when we tried bumping it, it just locked up, he said, sounds like the valves.

So, Col had this running before, how the feck, transporting it from his to mine have I messed them up
