Here's an update on my Bearkat Twister build, It's 95% done, Just need to attach the seat, and the front wheel bearings need replacing. But she's a beast, lots of power with the 8hp Briggs and Stratton. When I first got the motor, I had pulled it off a generator, so it had a tapered crankshaft. I got a correct crankshaft off eBay, and opened the motor up to replace. Also pulled the governor while I was in there. I wanted to use the original carb from the BS, but once I pulled the governor, it kinda messed up the throttle linkage, so I just pulled the linkage and the carb and replaced it all with a VM22 26mm Mikuni knock off from amazon, and it's awesome, super easy to setup and it runs and idles great after slight tuning. But I did have to have a buddy weld up a custom intake manifold, which worked out perfect. Because I switch to the Mikuni, I had to relocate the gas tank, since I wasn't getting any gravity feed for the fuel, the tank petcock wasn't higher than the carb fuel intake. Other stuff I did, new rear shocks, new rear wheel bearings, new tires, new throttle and my custom Mexican blanket seat. Really happy with this build, I love the patina, it's just a loud, dirty, fun bike to ride!
