Deja Vu - all over again

[dirtsurfer]

I took the shortcut in replacing the crankcase seals. Removing the clutch and generator, I drilled holes in the seals and screwed a couple of metal fixing screws a few turns and the pulled on the screws to remove the seals.

Leaks at the base of the cylinder are sometimes difficult to find.

Noted. Whilst mine is vastly improved after replacing the crankshaft seals, I still have some fine tuning to do. Maybe I'll lift the cylinder and see what is happening under there.

I have a similar issue, although I did a full engine rebuild on my ES250/2, the bike does behave a bit screwy with almost run away type screaming when pulling on the throttle (does eventually come down) and doesn't idle very well- tends to slow down to cutting off completely... I however am still aware that I really need to get the bike on the road and actually ride the bugger.. Some times running things properly and having a little ride loosens things up and makes a vehicle behave better.

Sounds and looks (from your video) like a similar issue. If you did a full rebuild though the seals should be OK. I also replaced the carb on mine as the original was quite worn .
