New to this forum, and it is full of info. I have a 1999 frame that I bought off ebay in great shape, with a title. I couldn't find a clean complete bike with a title in my area so I figured I'd build it. So I've started with used frame, new cases, used forks, and used swing arm. I want to build it with a mix of new parts, used and aftermarket parts. What I was hoping to find out is what parts should I consider going with aftermarket, like electrical, transmission or wheels and hubs. I've never really done anything far from stock on a bike, as my 1985 KX500 is bone stock right to the handle bars. Any suggestions would be great, and when I figure out how to post pics I'll do it. Looking at a Clark fuel cell right now, stock size?
