Very interesting argument in that post.. gonna go out on a whim here and say JJ is wrong, and bear is kind of a *.
Also if you are trying to find sensitive numbers like this and get accurate results why are you guessing on what the cureent tank has in it. Train it, it takes 10 minutes at most. Pull the fuel line and vacume line off the carb, use a syringe to apply vaccume to the line and drain the gas out. Premix an accurate amount then try. Just guessing is making your math skew away from the actual numbers.
I am assuming you are referring to like what was talked about here:

Makes sense to me!
As to why I am guessing what the current tank has, it's because I don't want to oversaturate again. So I'm adding best guess amounts that would take it down to minimum 40:1 territory if the pump actually does 70:1, might go 8 or 9ml instead of 6-7 just to play it safe, otherwise, I wouldn't play that guessing game normally.
The pump runs at around 70:1 but is linear to a curve if your plug chopping you would geta dry plug probably showing you are lean at the current and last mix you ran. Are you plug choping or brining the bike to idle then riding it right after the pull? Because I could my plugs show rich but if I kill the bike after hitting wot they show the true burn not the after coating of the oil that wasnt and hasnt burned off being sucked back into the bore on deceleration.
I'd do a plug chop, but I don't have extra plugs to spare, I will get on that.
There is alot of varibles to this, its not just slap oil in the tank and run it, dont change anything else. You should be fine at 64:1 if your math is right.

You would think I would be fine... heck
I THOUGHT I WOULD BE FINE at 64:1, but obviously I wasn't. I got plug fowling. No reason at this point to think that trying the same thing over again and expecting different results has ever worked for anybody. WHY it happened is anybodies guess at this point.. Could the "IOWA" Spree's have a different pump then a regular? Perhaps a restricted constant flow? I'm showing 2 different part numbers, the bottom one was replaced for whatever reason.
Bottom line at this point, 64:1 doesn't work for me (your results of course my vary), I am not at all comfortable with 128:1 but it does work. So best course for me anyway, is shoot for the middle at 96:1. That will give me a high volume of 36.5:1 when the pump linear increases to
MAYBE 50:1, and a low of 41.5:1 minimum. Maybe this is all wrong, guess I'll find out won't I? Taz was gracious enough to send me another BBK should I be completely wrong. Let's just all cross our fingers that I won't have to use it.
