Picked up this fox recently, it's in good shape for the most part. Seat is trashed. I think it's a fox spoiler but I'm not sure. The guy swapped a larger techumpsa motor on it, and swapped out the rear sprocket and took off the brake. I'm trying to find a stock rear sprocket and brake for it...

When I got the bike 25 years ago it already didn't have the original motor or rear fender. It's still a solid bike, but to me it's a driver, not a show piece. Sent from my iPhone using Tapatalk

Thanks, I dont think it looks as nice as a standard flathead, but it wasn't as bad as I thought. And it pretty much just bolted right up with the existing torque converter and everything. Couldn't ask for much better.

New member here, friend pointed me this way when I was looking for some info. Ive got an old blackwidow that use to really flog as a kid. Its sat in a barn for 15 years and I decided it was time to pull it out. Tried to get the Briggs motor in it running but game up. Ended up going with a...
