At the back end of last week i stripped the motor that was in the blue framed bike. The only info the previous owner had was that it was 700cc and had a Morgo oil pump but he had never checked. It went pretty well but it did smoke on the left pot, mostly on the over-run so i guessed at worn exhaust guides. Standard Hepolites +60 so no big wins there but when i went further sure it had a Morgo pump but a rotary one and Morgo rods with a nice balanced one piece crank into the bargain. Cams are 3325 which are Sports/Touring according to my list.
I popped a piston off then came to do the other but couldn't get the circlips out, there weren't any, i recon the engine builder must've had a phone call about that time. The pin has been fully floating and gradually making it's mark on the bore hence the smoke. If you are building an engine turn the phone off.
I was going to just leave the iron motor in Old Blu' alone but seeing the rest of the bike is in bits...
Everything looks as good as it did 5 years or so ago but ive changed the 5T cams for 3134's and am getting a bit deeper into cam timing with the reverse head setup.
5T tickler on left, 3134 rampant rabbit on right. If nothing else it will sound better.
