What oil is best? and what ratio?

[bwalker]

And FWIW ST burns like this in my cr500 as does my home brew blend of Benol and R50.
That's why I preach right oil for the right application..

Motul 800 has a 60:1 mix recommendation?

The 800 is 2% or something like that which translates to 60:1 for normal use.

Wow. I didn't know that. Thanks Mike

Is that what u r lookin for in an exhaust outlet? Dry and that color?

That was for 800 off road. It's in the tech sheet on their website. I give mine away so I can't check the bottle.

Ring lands, exhaust port and spark plug all look great on the bike.
Is terrible for OPE though and Benol is worse.

If the oil is combusting right and the motor is tuned right it should absolutely look like that. Same thing for a saw. You want the spark screens that color and dry.

I have a bottle but not sure which 800 I have. I will check.

My saws with Red Armor look like that

Bad in any engine. That sludge gets behind the rings and eventually hardens when exposed to heat. You then have what Keith observed.

 

[Keith Gandy]

Your either tuned poorly or your not combusting properly due to the load being too low for the oil.
Maybe Red Armor isn't the holy grail...

What r u talking about?? I ask if the dry color on your exhaust of your bike was what one should look like and I said my saws look like that with Red Armor?

 

[Keith Gandy]

U must be referring to your pic with the mower with the excess oil?

Thought you were talking about the lawn boy pic. Sorry.

Lol!! Now give that Red Armor the HOLY GRAIL!!!

Here's the tech sheet. It actually says 2% or 50:1 and decrease by .5% in normal conditions.

Mike Ronnie called Motul tech and they told him in a ported worksaw 800t at 50to1 and even 60to1 would be fine

I'm sure. Compared to a 80cc dirt bike a saw makes about 25% of the HP.
