Just measured the valve dia.
Inlet 34mm
Exhaust 31mm

I'll have a look at the sizes but reading the manual both valve guides should be the same 6.6mm int. diameter so the exhaust valves guides are knackered. Hence the smoking when running.
I'm going to get these replaced with new valves and springs.
I believe the engine is in good shape but a real close inspection of everything is needed, I'm checking the cyl bores later, they look good but who knows,
It will be put back 100 percent though no bodging here mate.
Here's a tiger 500 GP engine I built last year, runs a treat,

The engine is now stripped except the rods.
The bearings and crank seem in really good condition, so Im going to take some advise on it.
Originally the engine ran but smoked this looks now like the exhaust valve guides are worn, looking at the inlet and exhaust valves they appear to have the same stem diameter yet they are loose in the exhaust and snug in the inlet, this may be the normal if worn, again ill ask advise from DM Engineering and if need be they can put new guides in especially as I'm having new valve sets
All the gears seem faultless but not sure if it best to replace any bearings whilst its apart
Once the cases are cleaned I might as well get new engine studs fitted

Update on the Rickman build.
All the nickel plating should be back by mid next week !
Picture one. Some of the engine parts are back from cleaning , now you can see the condition better, all looks ok at the moment.
Picture two Tyres are now fitted and partially built.
Picture three I have altered the seat and any redundant holes filled, it will go off to be upholstered in a week or so.

Hi, are all the engine breather covers on the rocker boxes the same ?
I have one with a broken off fixing lug and need to replace it or repair it,
Easier to replace and cheap but not sure if all the same

Here's the engine at the start, sorry looking
the last picture is the clutch cover which needed to have some screwS drilled out.
That starter motor does not seem to come out, perhaps I'm doing something a miss.
It touches the rear right hand bolt fixing and wont go back anymore.

Just ordered a clutch tool on e bay £10.  I think this engine and the bike had been pressure washed and stood up a while, externally no oil but the ally's fluffy. Most Brit bikes are oily , the advantage is they clean up well... but drip on your garage floor The engine once stripped will go to the aqua cleaners. Quite often I have seen the cases are painted, is this the general rule for the CB's engine

Well you answered a question before I even asked it.
I stripped the engine today, well some of it.
A few screws of the alternator cover/ bolts seized in tight but I drilled them out successfully.
Where I'm at right now is head and cylinders off, clutch out except for the clutch basket which seems to need a tool... answered already
I still cant split the cases all bolts are out and there's very small case movement but around the rotor area seems not to budge.
I was assuming there's a seal behind the rotor area which would hold the cases back.
all other seals are out
The cases appear to have never been apart.
The valves look crappy and have been passing oil which the previous owner suggested.
Initial findings are new valves, maybe seats, but Ill have it all checked anyway
Rockers look really nice and bores look very clean
new pistons and rings, new cam chain and probably a lot more.
Anything I have missed on the engine that would stop the cases ?
Regards Keith
