damn it adds 110cc's that must be a big ass piston
i would poat this question in the soreracing forum. i think scott might be able to direct you in the right direction. like *** said"thats got to be a huge piston"
Like I said in your other thread, try http://www.lasleeve.com/ They've got some bad-ass stuff there.
THat thing is gonna rip your arms outta socket with that big ol bore!! It sure would be fun to ride one though.
:evil2: I have a 2mm overbore from Eric Gorr!This bike is so terribly fast,but i like the bottom end torque it has.Talking about hanging on...I love my Big Green monster!!!

As far as a 610 kit why so much of an over bore?

Nice ride. Over the next several months I will be building a pro level hill climb KX 500. I will be keeping everyone up to date on that project if you would like.

KX 500 based 635cc 650cc and 665cc

This thread is a little old now but I found it the other day so I joined the site to make this post.

I have been developing big bore kits for the KX 500 for about a year now. I am now testing a big-bore kit using a 97mm piston with a standard 86mm stroke which gives 635cc, I have already tryied a stock piston with an 88mm stroke which I get using a 27mm pin and big-end and offset boring a stock crank. The next step is the 97mm piston and the 88mm stroke which will give me 650cc after that I am looking at a billet crank with a 90mm stroke giving 665cc.

To use the piston you need to bore out your stock barrel and install a Moly-Iron liner, also a small amout of case machining is needed to take the larger skirt diamiter that this gives.

If any one is interested mail me [email protected] and I will give you full details.

Also available is a big-bore kit that I have developed to take the Husaberg 65o to 750cc.
