Calm down a tad......I get a bit bored with the simple topics but thats why there is general topic and YOUR advanced topic.
More oil means that there is less gas in a given space.

For the 500th time, it has nothing to do with viscosity. :(
Jets meter by volume, and for a given volume being passed there is less gas when more oil is present. The effects of viscosity in this case are too minor to be relevant.

Maybe when I ever get the chance to go to a dirtweek rich can explain this to me, but I still see it like this
for you out there who think less oil means richer, run your bike at 500:1 and tell me how rich it runs!:p
Ill stick to my 40:1 thanks!
OR run your bike at 5:1 and tell me how lean it runs!

I also happen to get less if not any spooge running at 32:1 whereas I used to get a fair amout of spooge at 50:1.

Rich I'll take it as fact that it doesn't have that much of an effect but I can't really agree with you when you say that jets meter by volume.

The velocity thru an orifice will be relative to mass AND viscosity of the fluid pulled thru it.

Maybe you are right, Rich on the viscosity thing...could you (or have you) set up a simple test?

"Does this mean the generic mikuni jets I get from a bin are no good. I notice mikuni jets have a symbol on them while these "generic" ones have an rd stamped on them. Are these "RD" jets cheap jets?:eek:

All of it makes sense except for that. I speak of my experience and mine only, but I have played around with 32:1,40:1,50:1 and one thing is pretty clear to me: 32:1 produces a lot more spooge than 50:1.

Does this sound correct? If not just point out the right direction.

I was mixing at 50:1 and using 927 oil. I then switched to 32:1 and Super M oil.....no spooge. Maybe it was more the oil than the ratio
