I just went through DV2000NJ's 650 thread, looks like he has upgraded his bars to something that I might like. Think I try those before going for a set up clip ons. Looks clean and maybe a little more comfortable for longer rides.
Wow, and I thought I was only here to steal ideas.
Just a heads up, you'll need some kind of bar riser to get the drag bars to work on the 650 front end. The way the brake line comes straight out of the master cylinder, it needs to occupy the same space that is already taken up by the top of the right fork stanchion, at least on my bike (not sure if your master cylinder is any different).
I lucked out that the bar clamps from an old Bultaco that's living in my buddy's basement fit perfectly. They are now mine on an "indefinite loan".
This is how my setup looks right now. It'll eventually be cleaned up and some allen bolts will replace the current ones.
By the way, I'm liking this build a lot. And you're giving me dirty ideas for a seat pan... Am I REALLY ever going to put that plastic bed liner back in the truck?
