18 250sx!

Both of us have always used castor 927 in our 2 strokes and love it. These new fangled ktms call for 60-1 is 927 still a safe choice at those ratios? He asked me and I really dont know.

Not to start another oil question but I don't want to steer him wrong!

We unplugged the white wire and probably going to do a 1/4 turn in on the pv adjuster to Tame it down a touch hes a long time 125/144 rider so the 250s gonna be a step up! Photo

I thought ktm moved to 40:1 in 18?

7/26/2018 6:46 PM

927 is probably safer than any other oil at extremely thin mix ratios. Let's ask Moto Tribology to confirm but I bet he'll agree that castor works really well for that.

Excellent choice! 1 tooth less on rear sprocket helps tame the hit also....I used to use 927 until I seen it completely seperate from certain types of gas, it also creates more carbon deposits than the newer synthetic oils. I think 927 is excellent for older air cooled , non powervalved engines. It is my opinion there are far better oils availible today. I use amsoil dominator at 50:1 in my 18 250 sx. 40 hrs, no issues...just my opinion. Tell your cousin to start working out, because that bike is a rocket ship....

You'd be better off with a cleaner burning oil, 927 is overkill especially on a 250.

I was a long time 927 user and K2 as well. I bought a new '18 150 and I bit the bullet and ran Motorex 2T at 40:1 per the manual. At 18hrs I did a top end and the piston was immaculate. The piston basically still measured new and the rings has decent life left. The powervalves were so clean it wasn't necessary to disassemble to clean them. I was very impressed. I thought what the heck and followed the manual's recommendations and I was very surprised.

motorex or k2 . I wouldn't go richer than 50:1 with ktm's suggested oil or something similar . they put hundreds of hours on these bikes at the recommended ratios during testing.

the higher the sustained rpm, the richer the oil ratio should be.

Motorex Cross Power 2T at whatever KTM recommends.

100 years ago in my two stroke days I ran a whole season on my kx250 with castor 927. I have never before or since seen such heavy wear and deposits foul a top end like that. never again

Congrats! Can tell you some horror stories about that dealership from 2013-16 time frame, they lost my business and I bought 4 bikes during that time period. I've heard they have better management/owners now. Hopefully you got a better deal and not the scummy sales guy that I dealt with a few times.

Never had seen it before using 927. Never seen it since. I would not put castor in my bike. Lets be honest, most people do it because it smells nice.

my cylinder was beat, I had done the top end three times, each time the piston was well worn with relatively few hours. The rotating drum power valves on the sides were COMPLETELY solid with deposits. In other words the cutout section of the rotating drum was completely filled in with deposits, s as to almost completely negate the effect of the rotating drum side power valves

Exactly what i'm running in my 17 150 and when I did a top end at 25 hours the piston looked great as well. Looked like it could have gone much longer.

Not to hijack, but I've been noticing that the motorex seems to burn better in my 150 vs the Bel-Ray I was running before. Noticed this at the last hare scramble race. Bike ran just as good, but way less smoke and no spooge. Haven't opened it up yet as I only have 7 hours on this top end, but I'm hoping it looks like yours when the time comes.

I'll say this, I am absolutely a bit biased against castor oils. That being said, Maxima does say it's good at any OEM recommended mix ratio but that's a pretty blanket statement.

If you're nervous, start a little heavier on the oil, like 40:1 and check it out after a tank or two. Check the plugs for fouling and keep an eye on the exhaust for excess oil. 927 has a pretty good reputation, but every product has horror stories, so just keep an eye on it.

I don't care what the jug of oil or the manufacture of the bike says, I mix 32:1. Always did, always will. I prefer Maxima Super M. I like the smell of 927 but I ride to fast to smell my own exhaust and I hardly ever find myself behind someone. smile

Since this is now a premix thread, anyone have separation issues running 927 in VP C12 fuel? I always am in the habit of shaking the jug before pouring it in the bike, but it would be nice to know.

It can separate even at normal temps in C12 and worse when it gets cold. I always shake vigorously before pouring in the tank, drain at the end of the day and the float bowl. I am so used to shaking my gas I do it out of habit even when I’m riding my 450... that gets a few weird looks I’m the pits! tongue

Good to know. Maybe I’ll just start using Formula K2 then.

If you search Pulp podcasts Matthes talks to a Maxima engineer. Talks about 2/4T oils. Obv biased towards Maxima brands, but there’s talk about K2 and 927.
I would listen to that before believing the geniuses in here. I think it’s show 336.

Best oil for the KTM 2T or any 2t dirtbike.
Motul factory 800 off road or the Denicol syn 100 both 100% synthetic ester oil the best in business.
Both easily 1to50/60
I prefer myself the Motul is price technical more interesting for me.
The Motul must be available in the US, the Denicol I don't now.

20 years of Amsoil has been good to my 250s at 40 to 1. I know nothing about these new 60 to 1 oils. Maybe they are thicker and more concentrated.

Huh? Have you tested it vs Amsoil and others?

7/27/2018 3:01 PM

Since this is now an oil thread, I will say that I use Klutz Super Techniplate. Best of both worlds. Mix the 250 and 125 at 40:1 these days.
