For those that advocate using 87 octane in these bikes

[Tim Tom]

So don't light 'em on fire.

I wonder if those tiny little things might not slip through the rubber anyway. Or in the case of H2 at 30-odd psi, react with the rubber in some unfavorable way. I did see (on TV) propane used to inflate a landing gear tire.

That may prove problematic given my preferred method of tire inflation...

This thread has finally gone wacky, btw.

Then you could have a bar-b-que after you landed.

just to open old wounds, pulled this from a Suzuki manual

All Suzuki motorcycles were two strokes at the time, so how relevant is it?

And 87 octane WAS premium-grade at the time!

It isn't.

What Suzuki meant was don't use rubbish fuel - and you could get some real crap in the old communist eastern Europe, for instance, that was smuggled across in to the west every now and then. Suzuki weren't referring to the octane rating. The UK owner manuals at the time always just said leaded 2 Star (our lowest rating) - 87 octane - for the whole range.

Second, don't know what part of the country you lived in in the early 70's, 98 super high test was available in Ohio.

First off, I was born in '79. Second, just a joke - relax.

[UncleMike]

Wow, why does everybody just assume contradition is an argument, seeing as you were from Ca, and in the early 70's emissions starting coming into play, and Ca was always ahead of everyone else due to smog control, thought maybe Ca only had 87. I was stirring the pot for the die hard octane guys, and everybody has a tender spot for controversey as of late.

Wasn't assuming anything. Just highlighting the fact that I'm younger than most of you geezers for a bit of Sunday-morning ribbing.

[UncleMike]

I thought maybe you thought I was getting mad or something, far from it, see, the post worked, started some morning coffee spilling <---should have used more of these

Yeah, I've never warmed up to the emoticons and that's my own reluctance to fully abandon typographic culture. Maybe I'm a conservative after all?

(Sh*t, we don't want this turning P!)

I wasn't salty in the least, I promise. Reading it again, I can see how "relax" could seem aggressive. I just meant it as "I'm WAY too young to have a reliably-informed opinion on the matter at hand, so please disregard my conversational contributions as their intended folly, nothing more."

You stirred the pot, so don't cry when ums gets spattered... I still think it's an interesting question, how does fuel grade and/or octane rating (I didn't mention octane either, just asked a question) compare from two stroke to four stroke engines? Impossible to tell from original fuel specs, but I bet a lot of folks that have both bikes and run on modern fuels have insight.

Well I AM RELAXED!!!!!!!!

I have two 2-stroke motorcycles and a 2-stroke twin boat engine.
They all run on premium fuel mixed with synthetic oil/dino oil blend.
Two are piston port engines and one has reed valves.

I used to be able to buy 100 octane at any station around here for about 32 cents through the mid '70s.

Just curious, what are the compression ratios, and what are the factory fuel recommendations? Of what vintage are they?
