I completely rebuild the entire engine 3 years ago now and still has just as much compression as when I first put it together. I just pulled the flywheel a couple weeks ago to check the crank seal and it's still good. Runs smooth and no odd noises at all. I store mine inside the garage that gets heated almost every day as I'm always working on something.
If there is no snow on the ground I actually ride it in the winter as much as possible.

Sounds good man - how do ya pull the flywheel to check the crank-seals, got to split the cases to replace the crank-seals.

You can see the sealing lip on the crank with the flywheel out of the way. I just make sure they aren't dry and or cracking. I also randomly (usually twice a year) pull the flywheel and clean any dust or rust off the coils. It's pretty humid here (Bay City, MI) and everything rusts quickly.

It's hard to keep a drivers license riding a 2 stroke dirt bike on the street.  If you drive within the law they are VERY boring.
