I have a fresh crank coming in next week,With a new top end. I wan't to give the amsoil another whirl,I did love the appearance of the crank when using the series 2000,but I did not like the look of the piston on the intake side. I won't get into details,It is a KX thing and my riding style. 50:1 was the ratio I was using before,and to be honest That is not cutting it with my motor and my riding style. I wan't to give the amsoil another shot,but I will be mixing 32:1 and I am tearing it down when the bad weather comes or 50 hrs whichever come first.

I can call Amsoil and have it shipped from lancaster pa,2 hrs away.I would like to give my business to a rep who sponsors this site. Who lives the closest to me can have my business.Please reply
 
This guy should be the closest....

KX455, I believe dominator and series 200 race oil are the exact same thing. I know enduro bikes are spooge factories when using this oil at 50:1.
 
Spooge comes from poor jetting and or gasoline burn characteristics.

I have been using mostly amsoil 2000 at 32:1 the last 9 months in my KTM 380 EXC. I mix the gas with 30% - 50% VP C12 race gas. After ridding all day there will be just a little bit of brown stuff on the end of the silencer with amsoil 2000.

I recently bought a qt of amsoil dominator and compared them. The old Amsoil 2000 has that ammonia smell common to ashless synthetics. The new dominator is almost orderless. Common to many JASO FC low ash synthetics.

So the 2000 formula has been changed when amsoil changed the name to dominator. I have not used the new dominator yet. But I do like the idea of a low ash for my KTM.

I know for me my KTM works very well with amsoil 2000 and Castrol TTS. In my much varied off road ridding conditions.

I had no problem with it running clean,I jet on the mark,thanks though.I know they changed the series 2000 to dominator.

Very true, but oil is also a factor. My current ride (cr500af) burns clean(silencer is bone dry) on just about any oil and the jetting is only 1 pilot leaner than stock. The KTM 200 I had would only burn clean with certain oils and this was after I played with the jetting big time(new needle taper,pilot,main,slide). High end point ester and cator based lubes create the dreaded black stuff easier than some of the cleaner burning oils.
as far as dominator be reformulated. It very well could be. A ashless oil for racing id counter productive IMO.
 
I believe any motor will spooge even if it were jetted properly. If the rpms were kept up and no tight riding,their is a better chance of this not occuring,which both Blano and Hirev probably know this.I never did have a problem with the end of the silencer drooling ,not even with 927.

Blano, please elaborate on a ashless oil not being a productive race oil.
 
Ashless oil refer to the additive package type. Low ash oils contain organo-mettalic additives control deposits that casue port blocking and ring stick. Ashless oils use a nitrogen based dispersant which only works up to about 300 degrees. Anything over this temp and you will have deposits galore on your power valves and ring grooves.
This is the reason it s a poor choice to use outboard oils in mx bikes.
 
BTW with my 500 I can ride the tightest, slowest enduro loops using a 32:1 ratio with out spooge and im no a class rider.

I agree with you. I ran 7 different oil through my KTM in the last 1 1/2 years. Their was some difference. I had one JASO FC oil that was real bad with pump gas.

KTMs do need jetting work I got more jets and needles and slides than I have ever had for any bike. Much of it comes from their excessive squash they like to run. Is is also why not all of them will jet the same.

Their very long spark arresters we have to run in the US don't help much either. In the end it was worth it because the bike works very well for me in my conditions.

I got to agree with ya on that. I would rather run a low ash oil myself.

I do pull my pipe a lot to check out for sings of being lean on the piston skirt and use the wet oil line method for jetting.

So I have been keeping a close eye on the ring belt area. Amsoil 2000 has done fairly well for a ash less oil. But I don't ride in sand or have any lean spots in the jetting. Both will drive piston temperatures very high very fast.
 
A little back ground. Let me start by saying that my 380 is very octane sensitive because of the big bore, poor squish band, 210-215 psi compression, and the fact that ride it mostly 3rd gear and 4th gear from very low speeds on up. Because the bike has the power to pull very hard from 3rd gear at walking speed. I just don't using lower gears (no traction) other than to pull away from a complete stop. It can have a high load for a real short time.

MX2T burned real clean with pump and race gas. My only complaint with it was. If I did not have at 20% or better load of C12 race gas in it. I would get pinging accelerating from low speed. For some reason the MX2T and HP2 were the only 2 of the 7 tested that had a problem like this running 100% 92 pump gas. With race gas it was fine.

I steered away from MX2T and HP2 because sometimes I don't always have race gas with me or I am temporally out.
