What oil and mix ratio's?

re: 'Keep in mind, more oil is not always a better thing..'

If your talking about making power, more oil is absolutely a better thing. That's not a personal opinion, it's a fact.

No, 2-smokers do not burn oil to make power. Oil does act as a sealer for both the ring/cylinder and piston/cylinder interfaces. That's a big deal on a 2-stroke.

I just bought a quart of Amsoil. I am trying it out this weekend. 50:1, really? 50:1 still scares me. :ohmy:

I thought 50:1 was pretty low to....but it said on the bottle that with this full synthetic stuff you could safely mix at 100:1 :think: which I am way to chicken to even try :ugg: . I've been mixing at 50:1 for quite a while with the Amsoil and it works great...it also really cuts down on how much the bike smokes :eek: .

 

[dsndblm]

Thanks for the reassurance! I will try the Amsoil out tomorrow and see how it does at 50:1 :thumb:

canadian are you using the 100:1 amsoil premix? if so, you should be using the series 2000 2 cycle racing oil. it says mix at 50:1. the 100:1 stuff is for weedeaters.

I use Klotz Supertechni plate mixed at 32:1 I don't know but I thought maybe 32:1 would be best cause thats what the manuel and the little sticker on the rear fender says. But hey what does Kawasaki know? :laugh:

I run Golden Spectro 46:1 in both my bikes,92 kdx 200 ,& 77 P.E. 250.You guys got me thinking . I looked in my original owners manual for my 77 Suzuki P.E. 250. It says to run a mixture of 20:1 !!! How come I have not had any problems running 46:1 for five years now ?

Just curious...:think: Why 46:1 or 42:1 ?

At 46:1 with 5 gallons of gas you'd need 13.91304347826087 oz. of oil

At 42:1 with 5 gallons of gas you'd need 15.23809523809524 oz. of oil

I mix mine 40:1

5 gallons to 16 oz. oil




Here's where I found the premix ratios:

just pick something run it and jet your bike thats what makes more power. what ratio u running cc i bet you get your chainsaw gas mixed up with your motorcycle gas alot. just kidding. cc if and when u read this if u would be so kind please provide me the link were u talk about the two sweet spots for the airscrew on the rb modded carbs. i half ass looked and might try again. went to low on the vf2 the other day. wow. oh sorry bout not starting another thread.

I think the manufacturers used to recommend 20:1 based on regular petroleum oil and SEVERE operating conditions. I had and air cooled RM125 years ago which was supposed run at 20:1 I believe I ran it around 36:1

Alot of people like to only buy a gallon or two of gas at a time. Just enough for one ride. So 3 oz. into a gallon gives 42:1.

I buy my Golden Spectro by the case in 12 oz. containers . I mix 1 container with 4.3 gals. of gas . Actually I was wrong in saying I run 46:1 .... should be 45.8666666:1 Sorry about that.

P.S. sorry if I mess up doing these posts ..... I am life long motorcycle enthusiast ,but brand new at computers.

I run MX2 at 48:1 with great results. My KDX 200 runs crisp. The spark plug is perfect golden brown with all the signs off good jetting/fuel mix. However, I find some black sponge splatter on my rear fender. What gives?

 

[nectar]

Perhaps you need to change the packing in your silencer....

 

[mlhend1]

Great thought..but I did that before my last ride last week. Do all 2 strokes produce some black sponge material out the silencer?

 

[mlhend1]

IF jetting is correct, does adding more oil (example, going from 40:1 to 32:1) produce more sponge/black material out the silencer?

 

[Roland C]

If I understand it correctly, adding more oil to the gas will make the mixture "thicker" thus leaning out the gas/air mix in the carb. This would be because the "thicker" gas/oil mix wouldn't flow as easily through the main jet. If there is less gas/oil getting into the combustion chamber, I wouldn't think there would be much more spooge with a 32:1 ratio vs a 40:1 ratio. This would only be true to a point, though. Obviously you don't want to run a 10:1 ratio or anything - that would definitely spooge like crazy. :whiner:

Also, it seems like there is this ongoing debate on what is the proper oil/gas ratio - like there should be a universal answer to the question. I don't have a ton of experience here, but I've used a few different kinds of oils and generally the ones that recommend 50:1 on the container are much thicker than the ones that recommend 32:1. It seems to me that using the ratio recommended on the container is better than the recommendation of 32:1 in the manual because different oils are meant to be mixed at different ratios. Hopefully I'm not opening up a can of worms here. :|

 

[KX02]

Sounds like you are jetted really well. The spooge might just be from when the bike is not warmed up yet. Especially idling with the choke could cause some build up of fuel in the crank to be expelled once you rev it up. :aj:

 

[canyncarvr]

It's nice the plug is a pretty color. ;)

You do say '...with all the signs...', so maybe the two things are not related although their juxtaposition would indicate otherwise.

The color of the plug insulator has not a thing to do with properly set air/fuel ratios.

Hence the 'black sponge splatter...', which I take to be 'spooge' ??

While the thicker idea may have some arguable merit, I think you will not find facts to support it. 'More oil' added to the gas indeed does lean the air/fuel mixture. Oil is not fuel, so the more of it there is, the less fuel there is.

40:1 is richer air/fuel-wise than 32:1.

 

[GhostRider32]

I switched to MX2T in a crunch during an unplanned ride. Best oil I have ever used. Stuff is synthetic and totally smoke free.

I think most of the KTM guys are converts to MX2T as well. Best of all - it is half the price of other racing oils and available anywhere. Give it a try - you will really like it.

Moridin,
What ratio are you using in your KDX200? I have an 03 KX250 I'm gonna try it in.

 

[wibby]

One downside of MX2T....

It does not change the color of your gas! I'm always wondering whether I added the oil or not :eek:

 

[Braahp]

adding more oil to the gas will make the mixture "thicker" thus leaning out the gas/air mix in the carb. This would be because the "thicker" gas/oil mix wouldn't flow as easily through the main jet

Yeah it may make it thicker but thats not why its leaner. It would be leaner because you now have more oil and less fuel per air in your mix that would be flowing through the carb.

 

[John Harris]

If you ALWAYS put the oil in the container before the gas, you will never have to wonder if you have put the oil in the gas or not! It also helps to mix the oil in by the action of the pump shooting the gas into the container. It sure is bad to be so old and have to operate in this manner.
