In order for you to have drained the coolant you have undone a hose somewhere, as there isn't a drain plug for the coolant.
If it wasn't leaking coolant before, that's where the leak will be. The chances are that it's the leaking coolant that caused the rear wheel to step out.

Your question about shouldn't the oil level have changed if you have coolant draining into the sump indicates to me that you have no issues there. If the level hasn't changed in one short ride (which of course it shouldn't) then neither oil is getting in and oil isn't leaking out, this is a coolant issue, unless you can see lots of oil on the outside of the engine. if so, clean it, refill to the correct levels and start the bike to see where it's coming from.

But sorry, i disagree that overfilling on these engines causes problems; that is normally a problem on IL4's and the seals , mostly on the camshaft seals, blow out of their seats.

Scotty, exactly what apart from the oil filter and drain plug have you undone?

Scotty,
Tony has a good point. Coolant with antifreeze in it is slippery, so if that was getting out onto your rear wheel, you would have some nasty slides, so are you sure you have an oil leak? Or are you just assuming that there is slippery stuff all over so it must be oil?

1) is the oil level still ok based onthe sight glass?
2) is the leaking liquid on the outside of the engine and on the tyre oil or could it be antifreeze?...what colour antifreeze did you use?

If oil level is still ok, and you used a red / brown antifreeze (I have green in mine so that would be easy to tell it was not oil), then you perhaps only have 1 problem.. A water leak

Have you been riding the bike since the rebuild with no problems. IIR you had some problems with the routing of the hoses around the thermostat, water pump and carbs. Did that get sorted.

OK so you can see the fluid in the rad. Warm the bike up and see if it starts to circulate (make sire the is oil in the bike first) Sounds like you may have a blockage somewhere. While the bike is warming up give it a good look over for any oil leaks or water leaks.

Your problem could be something as simple as an air lock in the system that is stopping the coolant level from dropping down in the system and therefore the bike not having sufficient coolant and overheating. You need to allow the bike to warm up to the point of the thermostat opening to allow the coolant run through the whole system. Obviously don't allow the bike to overheat, if it starts to get that hot then switch off. You have had the bike in bits, so the coolant has been totally drained at some point, so plenty of cope for trapped air if not filled correctly. So double check all the routing of coolant hoses and then make sure that there is enough coolant in the system. If you squeeze some of the hoses while the bike is warming up, this will help get any air locks out the system and at the same time you should feel how hot the coolant is in that part of the bike and know id it's circulating to that point.

Have you tested the thermostat in a cup of boiling water then. The best way would be to flush it all through with a hose. But you need to undo as many hoses as you can so it's got somewhere for it to come out. I suggest you also flush through the rest of the system as well. You should have done all this after draining the system before replacing with anti freeze/water, but hey ho. It seems you may be onto something there. You can easily disconnect radiator hoses and a couple around the thermostat housing and also the water pump. :thumbup:

I did flush it went changed it but seems one side is mucky and one side is clean now like water isn't going to one side but that wud say thermostat was jammed closed but I'm sure its jammed open if jammed open does this cause over heating ? I wudda thought it wudnt as it is allowiong it to still circulate

If jammed open it wont cause overheating unlike if it was jammed closed. If open it just takes longer to warm the engine up as it would be circulating around the whole system sooner as long as there's no blockages. You may have just shifted the crap from one place to another when flushing if you hadn't enough open hoses for it to drain out from.

Got to pop out now so wont be here. Catch you later. :thumbup:

Leave the thermostat out, reassemble and see what happens.
There should be no leaks of either oil or water and a stuck thermostat (which I doubt, actually) is the problem, as that can't cause leaks.
Find and fix the leak first.
It's not falling off, it's an upgrade opportunity.
