What oil is best? and what ratio?

[Flatie]

Also noticed this oily residue/carbon coming out of the decomp plug....is that normal or is it leaking? It's never used for starting.

That's not horrible for the 800. I would check the decomp to see if it's tight or just block it off if it is leaking.

Would you say that's leaking from the pic? I would of thought there shouldn't be any spoogy mess coming out from what looks like the centre of the plug. Any of your saw plugs look like that?

 

[mdavlee]

Looks to be. Pull it out and clean it and see if it seats better or plug it. Some of them that get used look like that a little. If it's not being used it should be dry.

I don't mind the tootie fruity smell of R50 it is just a little bit smoky for my taste i massacred many skeeters in my yard with it running it in my mower.

Again not to derail the thread again but does anyone know what oil they put un the Truefuel 50:1. My father only uses that stuff in is 336FR brushcutter

I tought I read somewhere here or on Another Forum that it was Motul 800T.

I can tell you guys that Irun Motul 710 (40:1) in all my saws now and the smell is nowhere close to 710. Put 6 thanks in my 562 and 545 this morning and after lunch I am using the brushcutter. What a pleasant smell

Thanks

It's not motul in that one. I don't know if they've ever really said. I prefer the 40:1 trufuel for canned fuel.

 

[Benelli777]

Ok newbie question. Does the 336FR carb will adjust ok or will Ineed to adjust (if it is an adjustable carb that is)

And yes I agree with you. I run 40:1 in my OPE. My father is still cursed by the big company's BS

Normal and its the reason I plug them with a brass plug.

 

[bwalker]

Plug out of my 550xp only ever run 800 @ 40:1.... Looks kinda dirty to me. Thoughts? Also the piston seems to have a fair bit of carbon on it considering not a huge amount of run time.

Nothing stand out in those plugs. The wetness is probaly from idling or low load prior to shut down.
With that said I have never been impressed with 800, but especially in a saw. It just doesn't combust well at load appropriate to normal saw usage.

Went riding for a little bit today. Got to the gas station and asked my buddy where he put my oil, "on the bumper, I though you grabbed it before we left". Well, i didn't grab it so there is a bottle of golden spectro out there somewhere.

I ended up mixing Amsoil Dominator 50/50 with Klotz R50 (didn't have enough to use one or the other) to mix 2.5 gallons and it ran pretty damn good.

 

[smokey7]

I have never used dominator, the warnings about rust always scared me off it. I'm sure it's great oil tho. Klotz is a oil I don't think I have ever ran maybe I should try it.

I've read about the rust on MX forums but have never seen it personally.

I could see in a boat or snowmobile it makes sense if there isn't rust inhibitors but not sure how a dirt bike under normal conditions would get moisture in it.

The guys i've known to use it have never had a problem. YMMV i guess.

Atmospheric humidity

And the whole warming and cooling thing usually causes condensation

Yeah i suppose it could, but enough to create rust? I guess if it sat for a while.


Floppy hat FTW!!!

Many dirt bike cranks show evidence of corrosion. And ester oils in general are pretty poor at preventing rust.

Few gallons of benol 40:1

That looks more like what kl200 does for me. Wonder why no wash marks? Combusting more completely?

I'd say that's why.
It's burning all of it

The transfers are working well cause that saw is very strong.
