Just got a Yamaha blaster 250 2 stroke. Rode it for a little while today when it started shutting off on me. Got it back home and tried cranking it back up it turned over a few times then just stopped. Hard to move gear shift and kick start won't even turn engine over anymore. Any ideas??
 
Well first off its a 200 and it's either top end went, crank bearings blow, crank melted itself due to running lean or no oil in tranny or the fly wheel is caught up. But first things first build or buy a leakdown tester and see if there's any air leaks causing any of these problems. Then proceed to disassemble engine start off taking stator cover off looking at fly wheel and then remove top end and inspect that if piston shattered or broke whole engine must me taken apart inspecting everything for damage and removing fragments. If either one of those time inspect crank and/or take bottom end apart.

Guy I bought it from "claimed" he rebuilt it from bottom to top because it seized up on him but I don't know how true that is or what he did to it when he rebuilt it. It was running fine this morning and it shut off and wouldn't start back up. After the kick start stopped turning the motor over my buddy pushed it down a hill and it started right up but didn't stay running long. I don't know what's wrong with it.
 
Here's a link and a photo of the top end kit that Blaster crazy is talking about.

These top end kits are very poor quality.
Think about it this way...
$75.49 + FREE SHIPPING! How is this possible when a quality piston on sale is about $75 alone?
Trust your senses! DO NOT PURCHASE ONE OF THESE.
Its most likely that the person you purchased your blaster from used one of these.
