starting to tear it down.cleaned carb and fired right up.but noisy.bad crank bearing.
 
Looks fairly clean ! keep the pics coming
 
Cleaned frame up and found 2 cracks. The head stay was missing when i removed the engine. So i found a frame local. For $100 luckily.1 year older though. Just have to drill and tap one hole for regulator. ordered head stay off ebay. Picked up some kawi green for new frame

That thing is sweet! At least you only spent $450 for your starting point rather than the $800 I did for my '92 YZ250. What year is that thing anyways, it looks like a late 90's or very early 2000's model.

I definitely miss having a two-stroke bike.

It's a 98. Just saving the older 2ts.i ussualy have a project to play with.its not about the money. Sometimes im ahead sometimes behind. It doesn't really matter it's a hobby. Fix them ride them have some fun.this is going to be a spare bike for now.my blaster is fully rebuilt. So unless i want to make it shinny. This is it. Yz just started smoking.so i will be putting crank seals soon

Swingarm and linkage bearings were good. So they were cleaned and greased. Everything is nice and tight. Installed swinger and shock.plus the aftermarket pegs.
