Locked up blaster

I went to look at one from craigslist. When I got there the guy said he came out to start it and after 5 minutes of running, it shut down and locked up. Said it was maybe cause of the oil injector gummed up. I figured a bad piston or something.

I wasn't sure where to start so I took the head off. Nothing in the way or broken. Then I took the cylinder off, no problem there. I took the primary off and removed the clutch. This freed the transmission up and rear wheels would turn but the crank was still seized.

To the other side. I removed the flywheel cover. Low and behold, one of what I assume to be magnet screws had worked out and jammed between the flywheel and the crank case wall. I had to laboriously hacksaw the screw with an open blade hacksaw. I could see no other way to get it out without fear of damaging the case. Surprisingly it didn't crack it or break the case.

It was missing another screw so I need to buy a flywheel remover. I tried to tap it loose with a hammer before I realized it required a puller. Will probably need to replace the flywheel now.

Now to the question. Will the Yamaha dealer possibly stock the puller and the flywheel. We have a big dealer close to the house and I will stop tomorrow, but too late tonight to call. Also, is this a pretty standard part? Kinda one size fits all, or do I need to get numbers off the vehicle? Where would they be located?

I got the blaster, a spare lower end, and a helmet for $350, so not bad if I do say so myself. The spare lower end has a flywheel on it, but I'm not certain it is good and with no way to test will probably be best to just get a new one.
 
run the spare they dnt realy go bad if its a lil rusty take soem scoch brite or fine sandpaper and removeit ad a puller u can get on rocky mountain or your dealership should have 1 cause this type of puller fits a lot of brands all im sayin is use wat ya got and save the money for modds like a pipe or something
 
try the spare it is already paid for. and not verry hard to replace if itis bad. the puller is relitivly cheap $15-$20 and works on other models of bikes as well your local shop probably has one and is probably CHEAPER than the dealer.
 
That's a great deal for a blaster, doesn't seem like too big of a fix either. I would throw in a new top end while your at it, then you are good to go!
 
I used the whole spare bottom end. It looks to be in much better shape.
I have the motor together and need to put in the frame. I lost the clutch push rod ball and still need to replace the tie rod end. I tried to get the part and they wanted $53 just for one ball joint.

I told them they were crazy and left. May not be able to go back there though.
Good news is I found several ATV junkyards here in Atlanta and will have a look around this next week.
