Hello everyone and thanks for the add. I recently acquired a Montesa 349 white wonder circa 1981. My first Montesa restoration.. I am quite alarmed at the lack of good workshop manuals in English and in depth. Just a few asks - what ratio of fuel to oil and should I use and which oil - synthetic/semi synthetic/mineral oil ?(for my other bike I use rock oil pp2) Also what other oils should I be using for other internals. Thank you.
