Had the timing inspection cover over two RE5's yesterday doing routine tuning.
However, noticed that with the same amount of sump oil and engine running, the area revealed under the timing inspection plate was very oily on one bike while the other was pretty dry.
Any thoughts on what might be going on here, if anything ?
Thanks,
Wayne

Hi Wayne,
First thing is to remove the breather pipe on the top of the same cover that the timing inspection cover is on.Start her up and if there is any blow-by,smoke etc coming out the then motor proper is suspect.
The rotor side seals can break up and also the the surface of the side plates can suffer causing combusted gas to leak down into the mechanical crankshaft oil seal (2 metal rings)then that gas escapes into the outer engine case via the oil return.
If this is the case,then a simple compression test will show a lower reading.
Good luck and i hope its not the issue.
Regards Roy

Thanks Roy, sounds serious and I'll follow up what you say with reference to the book. The good news is that the bike in question is a very strong runner and very clean throughout the rev range in both power output and carburetion.

In that case,it might have a different baffle plate assembly inside the casing with the timing inspection hole.
Some of the early bikes do have a different baffle plate with may be more or less efficient giving the impression that its more oily inside.

The two bikes are separated by about 1200 engine numbers so looking at the book this could be the issue...different baffle plates.
Have another early model turning up soon so will compare with that one.
Thanks,
Wayne
