I have a 71 cb350. Rode it for 2 months, and then started to tear it down. Got a 750 front end with 2 inch shorty tubes from cycle exchange and progressive springs. Much better stance than the PO, he put on tubes with a 7 inch stretch, looked crap and rode worse.
I was going to do a total tear down, but I have to get it back on the road. I can't stand to see her just hanging out in the garage any more. Going to finish the seat, buy a battery, fill her with fuel and head out. Then I add a few things down the road. Rearsets and such.
