Crank seals

How difficult is it to replace the crank seals on a 2 stroke?

Bike is a ktm 125

Lot easier than a 4 stroke.

Haha cheers Steve.

Had a quick browse online, seems the only fiddly aspect is the power valve linkage/timing.
Some claim it can be done on a two stroke in under an hour.

I done a kdx 125 when i was 17 never done it before just dived in. Had a few bits left over after but ran alright after
Don't think there any timing to do with the power valve.

this way over my head thought four strokes didn't have crank seals

stick to riding them wolfy and yes a four stroke has seals as well

Learn something every day look

The way the ktm is shooting oil out the exhaust I don't think mine has any either

I just just a bit less 2 stroke you,l be alright then

I think you can replace the seals without splitting the crank with a little ingenuity.

Put a clock (DTI) on the end of the crank to see how much radial movement there is!

And the seals wear a groove in the bush which doesn't help...
