Three questions, since I'm brand new to these things:
1: I'm assuming the 20:1 ratio is way off given modern 2 stroke oils (I use a mix from Royal Purple to mineral to Castor to etc, etc, etc). What's a more correct ratio? I run 32:1 on my 83 CR480 air cooled and my 89 250 liquid cooled.
2: I can get ethanol free but it's 89 octane? Is that better or worse than the 91 octane that has corn in in?
3: Is there anything I must do to ride it reliably? Meaning are there any changes that people have learned should be done right from the beginning? I saw something about adding more than enough transmission oil? Anything else? I run evans waterless coolant in my other old Honda 2 strokes because of the magnesium covers that got ate to hell, is normal anti-freeze kosher?
As you assume, most guys run 32:1.
I'm not sure on the fuel question, pick your poison.
Keep using the waterless coolant, I like it better also. I would suggest keeping it as stock and original. You can modify the air box with a second snorkel tube. It is said that the original design choked the
Engine a bit. Also, an aftermarket head is a nice upgrade to help with reliability.
