I purchased a 444cc kit for my 2000 yz 426. I've got most of the crap taken off the bike in prep for removing the engine. When I got to the swing arm bolt, I realized it might be easier to just change the cylinder/piston while its still in the frame. Is this possible? Any other tips on DIY rebuild? BTW, I got the kit from Lukesracing.com. Very nice people to deal with and it was in the mail the same day I ordered it.
