Had a T140 that we adapted a Honda rear wheel to , oddly enough it didn't require much , the axle size from the Honda fit snugly into the swingarm slots . Honda employed small rear sprockets , and even the largest available was something like 6 teeth smaller than the Triumph sprocket , meaning the gearing was stupid tall . The engine was running a 3134 650 exhaust cam , a 2 into 1 exhaust , and electronic ignition , with a mild port job by Jerry Branch . It would in fact pull at 2,500 revs in 5th gear on fairly level ground , probably a true 65 MPH . Made for a smooth ride , even at 75 MPH it was not revving high . Lived in a rural area , never had to deal with traffic . It was a bit sluggish at low speeds , and was a little hard on clutches , but it did work on open roads .
