Aus delivered 126/niki ring size

[KAL SPL]

Need to buy new rings for my 90 model FSM niki but have discovered there is 2 different sizes 73 and 77mm can anyone tell me which it would be please ?

[Bar Vitelli]

Probably the bigger one as 73mm relates to the older 594cc models.

Rusty will know for certain and will probably do you a deal.

Orange Nsw , bought the 77mm as I measured my pistons once I removed them.

you got pics of your rebuild? you must have few k's on yours. when i did mine, the rigns were ok, but the crank bearings were gone. propoably somethign to do with the tiny oil sump and high engine temp

It's had a hard life and my maintenance routine is poor , I usually put more oil in once the light started flickering for low oil pressure , can't understand why it broke :p the stretched timing chain was just the nail in the coffin.
Pics and rebuild in my showcase thread.
