Mk1 Cota 349 Piston Ring gap

Featured Replies

Hi,

It's been a while since I last posted.  I am finally getting round to rebuilding my Cota 349 1979/80 (an early one).  It's only been stripped and in boxes and drawers for the last 12 years, so I'm moving quickly on this one🤪. Can anyone let me know the correct piston ring gap for the standard bore please?  The bore is good, not oval, and has hardly any wear, so I am just putting new rings in.  I have the new rings but wanted to check the gap before assembling.

If I remember I'll post some photos along the way.  I've already rebuilt and re-spoked the wheels, frame powder coated, new shocks and forks rebuilt and fitted.  Going to have to do the forks again though as I've realised the previous owner missed a couple of parts out. So I'll be ordering new internals. Here's a quick peek at the story so far (if you're interested).

Thanks!

Thanks for the quick reply Majesty!  I have a list of parts for the company you mentioned, so I'll give them a try.

Thanks again

Standard piston ring end gap is 0.20 to 0.35 mm (0.0078 to 0.0137 in).
