I was wondering if anyone out there has installed a big bore kit in their 450? Where can I get a good buy on a kit? Is there a down side to installing one?
Any input would be great. Thanks :)

To bore your bike you don't really need to buy the "kit". You can buy each item in the kit seperate, if it is cheaper, it was for me. Buy the piston you want, and then send out your cyclinder (and piston) to get bored and re-nikasiled. Then buy a gasket kit that is for the right size bore from cosmetic.

But if you don't want to hassle with that I would go with thumper Racing's kit, they have been around since the first big bore kit on the YZ(M) 400.

Hope that helps..... :)
