BSA 1971 Thunderbolt
Bike designed and built by Decent Cycles. This is one of a pair of bikes; the second is a 1972 BSA Lightning. It was intended that these bikes be sold as a pair; they look very similar as you can see. As seen in the month of May 2009 Brit Bike Calendar. Now with new paint work.
The motor was rebuilt by E & V Engineering, Howard City, Michigan. Special head flow work, cast iron oil pump, SRM oil pressure relief valve, balanced crankshaft, all new bearings and bushings, transmission tuned, positive shifts in all gears, all new clutch plates, new fasteners, new pistons (J&E) .040 over- motor is in A-1 condition. A new duplex primary chain has been fitted. A Norton type oil filter has been added, all plumbing is done with auto transmission line, and all the fittings are Oetiker type. All fluids have been changed three times during a careful break in. Now has 1000 miles on the bike. A fender drop kit has been added.
Brand new cloth wrapped wiring harness, which runs the Podtronics regulator, ISO mounted. All connections made with professional crimper and are heat shrunk wrapped for strain relief. A Pazon ignition system is installed, with new 6 volt coils and a new key switch. A new halogen light bulb has been fitted to the headlight. The horn and headlight are operated by relays made for me by Eastern Beaver Co. unseen under the tank. Tail light is LED type bulb, made for positive ground electrical systems. The system uses real motorcycle duty relays. These take the amperage strain off the handle bar switches and provide a direct fused link to the battery. The horn is loud and the light is bright. The wire color codes on this system are correct for positive ground.
BSA 1972 Lightning

I bought this bike running, (13,500 miles) I carefully checked it out, and found the motor and transmission to be solid. Uses no oil and has 150 lbs of compression on both sides. The clutch friction plates and the clutch center cush drive have been renewed. A new duplex primary chain has been fitted. New drive chain as well. The carburetors were pulled and all new jets fitted internally; also sleeved by Bruce Chessel (Triton Engineering). New hand-made nylon-lined throttle cables were fitted. I also added an SRM oil pressure relief valve. New air filters and rubber air intake tubes. The frame has the original black paint; it has been touched up, as it did not need to be completely torn down and recoated. The side covers were painted with black wrinkle paint. The wheels were as stock, polished hubs, spokes and rims decent; again, not worth ripping down and replacing. Front rim has no blemishes and the back rim has a few spots from an old style battery over charging. The new battery is an AGM type no more problems.
Brand new cloth wrapped main and headlight wiring harnesses, which runs the Podtronics regulator, ISO mounted. All connections made with professional crimper and are heat shrunk for strain relief. A Boyer ignition system is installed, with new 6 volt coils and a new key switch. A new halogen light bulb has been fitted to the headlight. The horn and headlight are operated by relays made for me by Eastern Beaver Co. unseen under the tank. Tail light is LED type bulb, made for positive ground electrical systems. The system uses real motorcycle duty relays. These take the amperage strain off the handle bar switches and provide a direct fused link to the battery. The horn is loud and the light is bright. The wire color codes on this system are correct for positive ground. The stock tachometer and speedometer work; the cables have been renewed.
There are 5,400 original miles on this bike. Some modifications have been made.
