1973 Fox Thunderbolt

[SamM]

Drove into Pittsburgh today and picked this up for an awesome price. It came with the stock Tecumseh 3.5hp engine, the stock CVT and all the extra parts to complete it. Well, almost all of them. It needs fenders and a seat. Someone has foam and a piece of plywood that’s cut to the wrong size for it. The seller said that it came with the bike when he bought it. The plastic fenders that came with it are going into the trash too. I have already sourced fenders. The fuel tank looks perfect inside but needs a couple dents pulled and some paint. I’ll paint the frame and clean up the wheels.

I honestly do not need another project but this was too good to pass on. My thought is to put the Predator Hemi engine on this instead of my Coleman CT200U. The parts for the 212cc Hemi will arrive tomorrow. I still need to buy a CL-1 cam for it. The new engine would make it sort of like a resto-mod. A little new stuff mixed with some very cool old stuff. Not sure which way to go with it.

The Fox Corporation listed the Thunderbolt has a mini-cycle not a mini bike. These are apparently very rare and worth some money. I’m still researching it before deciding on what to do with it. The stock Tecumseh engine runs. I bolted the stock CT200U engine into the Thunderbolt and it fits. The Hemi will also fit.

The shocks were reversed, so I switched them back but it really needs new bolts. I’ll get those tomorrow.

Does anyone have information on these bikes? Parts sources would be great too. I’m not finding much out there.
