I really did enjoy that. There's something about gearboxes..... Nicely filmed too - it was very easy to follow. Thanks again!

Another well done from me, I am very curious to your hypothesis of what caused the issues “ as told to me when I got this engine”. Thank You for sharing your talents here on KZbin.

Yeah, I remember the oil pumps very well when I started out on my FS1E. Petrol was 67 pence a gallon. Pretty much fill the tank for a quid! I feel so old I am going for a lie down now......

Don't remember them Bill, must have been before my time, I just remember the yellow ( ? ) wheeled tanks that they brought to your bike ( or Wartburg ) selected the ratio and dumped an amount of oil into your tank.
