Does anyone else have a problem with their swingarm cracking almost in half? I have had to replace my '00 Mojave's swingarm about every two to three months. I am now on my third swingarm after cracking the one I have now in a motocross at Sleepy Hollow MX track. They both cracked around the welds between the axle housing holder and the swingarm itself. The only thing holding it on both times was the shock mount itself. I know I ride MUCH harder than most people and it's probabely me just beating the sh*t out of my machine but would like to know if this is a problem with other people too.

 

Just a few days ago I was looking at my Mojave and the swing-arm was cacked down one side of the weld and and the side was cracking to. So now I have to replace it.

 

I've heard of this problem previously. Are you replacing them with stock or aftermarket? If aftermarket, what brand? I'm curious if there happens to be a bad batch of metal out there, that they are making these things out of? You may want to try switching aftermarket brands. Also, you may want to do a web search (from Infoseek) on "cryogenics".

Basically this is a practice of slowly freezing (to nearly absolute zero) items (of any material) and then slowly re-heating them, and repeating the process several times to molecularly strengthen the item.

Let's take a forged piston, for example. A machine pounds this piece of material into a shape. Molecularly speaking, it looks like a plate of spaghetti (going in no particular direction). After this piston has undergone a cryogenics treatment the molecules look like uncooked spaghetti (straight and in perfect rows). I've read results of 100-300% stronger parts and it does NOT make them brittle.

I've heard of many Nascar and NHRA racers using it, even NASA. It's relatively cheap too; they do it by the pound. You can get an entire automobile engine done for under $400.

Who makes an aftermarket swingarm for the mojave Kawasakikid? I have been looking for one but can't find any. I have just been replacing them with stock ones.

 

I don't know off the top of my head. I assumed they made them. I'll do some research and get back with you.

 

Try the page below, they have a ton of commercial links. You may be able to find someone that sells or will fabricate a swing arm for you.
