Valves difference between M-N & K-L models of 1100

[mx13]

Hello

I have nice N 1100 which has 78000 miles on it, so need to be rebuild/eat alot of oil/! So far bottom end is easy, but for head job I noticed that all oversized valves offered into the web are for '86-'90. So because of the separate rocker arm and shims, I belive there is any differance. Right now in that moment the head is still on, and can't compare the valves vs the old model. I'll be very grateful if you guys help me with that !

Thanks in advance!
Regards,
Martin

86-90 valves have 2,8mmm tip length, 91-92 1,7mm tip length. Valve spring retainers different but same valve keepers. Only standard size shim valves available, I think.

Here's some oversize 91/92 valves.
