No need to really tear it all apart unless the crank moves if You tug up and down on it, the seals are an easy swap other than the flywheels on the old 2-strokes tend to seize up pretty good and can be a bear to get off (best to start spraying everything with PB Blaster ASAP and keep doing it every time You remember until You actually tear into it) ...

I had an 88 that would hit 28mph with a 5" lift and 22" tires, and that was stock - the 1988 was a one-off year though with the "High Output" 2PG engine that put out 11hp, the stock 86-87 puts out approximately 9. The main difference between the 2 is they went with the BV24 carb in 1988 instead of the standard BV18, and the exhaust was totally different and far less restrictive - the easiest way to add some "get-up" to the older 2PG's would be to find or fab a less restrictive exhaust and replace the BV18 with a BV24 - I say "or fab" because being a one-year exhaust, the headpipes for the 88HO is nearly impossible to find, even used, and the mufflers are out there (both NOS and aftermarket) but are pretty expensive.

Here's a fast way to check the seals, jack up the cart and run it at a low, consistent speed, then spray some starter fluid, WD40, etc at the rear where the crank exits the engine. Then do the same only spray into the flywheel area up front - if either results in an increase in RPM's, that seal is leaking (easiest to do with 2 sets of hands). Seals are around $6-10 each, and provided the flywheel doesn't hold on for dear life *too* bad, it's about an hour job total. You'll need to make a clutch puller (there are many threads on that here) and You'll need a small-engine flywheel puller, other than that a little blue loctite to schmear on the seals when reinstalling them and it's all simple hand tools.
