Two-stroke crank seals?

[Stylo]

How long will crank seals last if the Bike's only been started every 12 weeks , run for about 6 minutes then, put away again for another 3 months or so ?. And repeat the above.

And how long should I run it for when I've started it to keep some pressure in the crankcase, or is about 6 minutes enough ?

Bike's a low hour, CR500 01 , don't want to ride it because of it's A1 condition but also don't want to have to strip the motor and replace the seals .

Bike's a very low hour, mint CR500 01 , don't want to ride it because of it's A1 condition but also don't want to have to strip the motor and replace the seals .

It wouldn't be a major job to replace the seals if you ever had to.

It's just a matter of removing the rotor and stator from the left side and the clutch cover and primary gear from the right side.
