Bonny Oil Change

Can you give full details of your bike please Beefy, sounds like an original Bonny?

 

One of the "old boys" will be along soon, to help you Beefy. I'm too young to know

 

Hi, Beefy ..... really not sure but I always thought that there was a drain plug at the bottom of the frame tube behind the engine. I also thought that the filler cap had a dipstick built in to it. However I could be very wrong as it is many years since I knew anyone with an oif Bonnie.
If all else fails look out for someone who already has such a beast (or even a late BSA 650) and ask them. You could also try picking the brains of a parts supplier/dealer for such bikes.
Sorry I can't be more helpful.

 

Has it not got a drain plug on the frame on the down tube at the rear of the motor been 30 year since i had mine

 

If youre going to try to free off the clutch that way make sure the ignition is OFF and there is a clear run in front of you and that youre standing astride the bike holding the front brake on ........... just in case.

 

Correct.
Standard procedure with older Triumphs. Well, it was with mine - when I were a lad!
