Lots of performance modifications you can do on that TS250 if you want btw.
The motor is very under-stressed and fairly mediocre-performing in completely stock form, steering head bearing is loose balls, swingarm bushing was just plastic. 21" front wheel was a typical upgrade for off-road and the stock rear shocks are just spring holders. Plenty of things you can do to make more power if you need it

Same motor and carb was used on Arctic Cat Lynx snowmobiles and those proved near indestructible (in stock form)
... if you are riding it on street you should true the brakes, it will make them work a lot better.
We also used to cross hatch the pad face with a hacksaw for the wet.
... the rear brake stay and actuating rod can be modified to reduce rear wheel hop too :|
... stock footpegs are almost dangerous and too far forward and the stock handlebars bend super easy

also good candidates for upgrade.
Hooker exhaust was nice and reasonable sound for period street legal use, if you can find one.
