Tried to put up a photo but I was not able. Operator error I believe.
It’s a 1971 BSA 650 Thunderbolt. Rated at 46hp, single carb, 9:1 CR, same cam as is in the Lightning twin carb model. When accelerating the cam begins to be felt at 65-70, it’s a pretty quick surge…feels good. Period magazine road tests of the time show an average top speed of 100-104. This single carb model actually had a quicker time in 1/4 mile runs than the twin carb Lightning, but only by a few thousands. 2200 miles since rebuild. The ride is smooth; good suspension. Runs like a new machine. I’m Going easy with it due to mileage, but while out for a ride yesterday I let it run from 70-90, 2/3-3/4 throttle, the effects from the cam kept getting better (it felt pretty quick), handling was rock steady at speed. I’m anxious to see how it performs once I’ve tended to a few things first to insure a safe ride through the sound barrier. Tires look they should with just 2200 miles, but are old and need changing. Found a couple of bolts loose (nothing serious) so need to check everything to be sure. *** Everything works on this bike. *** When I checked the oil it was CLEAN. The tank is clean and has been treated. Overall, I am very satisfied with this purchase. It was $4K and I consider this a good deal.
