I actually just pulled the center stand of my '76 750F. It's a 4-1 exhaust, and I didn't realize how much the chain was scraping the stand. That said, I bought a swingarm stand from Harbor Freight for about $25. Great deal, and lifts the rear w/ no problem. If I need to get the front off the ground I just use a jack & a 2x4. Easy & inexpensive!
