New to this kind of fun, just got a 02 Blaster (all stock) 2 month's ago.
Locked it up last week. Piston was locked as well as the bottom, broke the bottom free & thought I might have got lucky but after putting the jug (bored .050 over + new top end) together found out the bottom was cluncking![img]i/expressions/face-icon-small-sad.gif[/img]
I'm some what mechanically inclined (top was no problem) but I don't know what's below. Where can I get a break down & should I attempt this on my own?

That will give you small brake downs for parts. I used this to get the part #'s for all the bearings and gaskets needed when you put things back together.

As far as tearing it down. Be sure to get a manual on your wheeler. Tearing down the bottom end and splitting the case is no cake walk but, if your handy with a wrench and you have a manual be patient and you'll probably be able to handle it. I just tore into my '98 blaster last night. Found a few bad bearings that could have caused serious damage if left unchecked. Be sure to check your out as well. Good luck!

 

Here is a very helpfull link. The pictures are of a banshee but it gives you a very good idea of what your looking at doing.

Good link JLsparky7. That will get you started however, all of that is a walk in the park. The real fun begins after all that is done and your getting ready to split the case. : )

A little advice dirt slinger. Be sure to go get a rotor puller. Its a tool that is required. I tried everything in the book to get it off and had to waste my weekend then wait until Monday to go to Yamaha shop and buy one.

 

I consider myself mechanically inclined, and I leave the bottom ends to someone else. There are so many little parts in there and if you get one out of place or leave one out you'll be screwed! I just had my crank replaced and the shop only charged $140 to split the casing and replace the crank. I thought that was a pretty good deal and was cheap insurance that it was going to be put back together right. If you do it yourself, good luck!

 

Thanks guy's! I got 2 estimates a world apart. One for $350-375 & the other for $600-700!! 140 for that crank sounds like a good deal.

Koopa thanks for that link, are the prices there cheaper than local guys?

Yeah, but I bought the crank myself and took the engine out of the bike and took the topend off. $140 was just labor to tear down the bottom end and put it back together. $350-600 might not be too bad if thats parts & labor.
