I got some work done on the old pre unit Triumph drag bike this evening. I pulled it all apart and have the frame ready to sandblast. Got the motor on the bench and pulled the timing cover and found this, very cool drilled timing gears and BTH magneto advance. This got me excited so I pulled the top end off as well. High compression pistons, +.100, the rest of the bottom end will come apart this weekend. Looks like perhaps Harmons Collins cams, we shall see for sure when I split the cases.
