I just picked up from a field about 3 blocks from my house a very complete 1974 T-500 bashed in head light and missing the left side cover.
of course it needs a little love. But hey it was free what can i say i am sucker for old scoots.

when you start looking there are a lot of bikes leaning against shed barns and cellar doors,across america.
Most people have no love left for them and give it to you for getting the junkster of thier lot.
Good find...now is the true fun part "seeing whats wrong with it and why it has been sitting.....its really funny when you find they have been sitting for a few small items like cables and clutch pack.Or both. Just goes to show these bikes were very over engineered.Keep us posted and do post so pics we love looking.

The t500 also makes an awsome race bike (so I am told). Lets see some pics.
The can make great racebikes, and are one of the few two strokes that fit in the 500GP class. I forget the name of the guy that used to race one with the USCRA... he didn't do too much to it and it was pretty quick. Needs chambers, of course.

If you want to get serious, the heads need to be reshaped to get a proper combustion chamber. And lotsa the British t500 racers seem to like stuffing the cases to raise crankcase pressure.

But clean it up and ride it. Good reliable bikes. And very fast for the time.

Follow up on the T-500 pulled both heads no detonation looked good
Pulled both the left and right jugs one was stuck got it free cleaned the barrels with a rag and carb cleaner dang looks brand new look at the pistons dang looks like stock bore the motor now turns free
I tell the wife if it turns over i can make it run.
I will post up some pic of the barrels and the bike even the front tire looks brand new some old goodyear type.
Some clubmans are on order after i get it running some chambers are in order.
Then take it apart brace the frame, swing arm paint polish

Even if the T500 turns over there are a few things to know about the bottom end. If the seals are bad the crank needs a rebuild (which can cost up to $350). T500s in stock form hardly smoke at all when they are running, but when a crank seal goes the smoke like a mother. My t500 engine is torn down right now because the right cranck seal went on my engine and it looked like I was spraying for misquitoes in the neighborhood.

Another thing about a t500 is that on some years the oil pump is driven off the clutch so if you pull it in and hold it at a light the pump stops spinning too.

lol.. silly japanese... That's almost as bad as putting the clutch on the end of the crank and then expecting to spin that unbalancable load to 9K rpms. Early Yamahas did that.

Yep...clutch on the crank....I spent $700 to correct that design flaw on Mary's 70cc racer...which turns about 13k....stock setup explodes nicely around 11k.
