Yeah, if it's rippin and you're OK with whatever level of smoke and spooge you have.. run it!
It gives extremely nice looking plugs as well lol. I’ll pick up some maxima and report back. It’s tried and true for me.
Doubt anyone is interested in my super specific setup since it's jetting - you can't just bolt it in and go.
This bike ran SO smooth and linear and revved to the moon. It just wont stop pulling. It may have given up some hit, but if it lost a point there it gained 3 points in rideability. For me, this is time off every lap. It ran so perfectly crisp and clean and the sound was indescribable. Only people who ride two strokes understand the sound of a perfectly jetted 250 with a shorty. Anyways, thanks for the help FGR. I appreciate the recommendation on the SuperM. It's a great oil. so far and way less dirty, even mixed with about 20% 2-R.
In your experience, why would a YZ250 smoke a little bit out of the powervalve hose when being warmed up from cold? When I just started mine this weekend I noticed a little "phantom" smoke coming out during warm up. Its got exactly 30 hours since new and I'm doing a top end this weekend as preventative/interval maintenance. Totally stock. Same setup as the gobbler is running basically.

It’s not unusual for a puff out the PV breather on a YZ250 during warm up, especially depending on rich jetting or the oil being used.
Good idea changing the piston at 30 hrs. The OEM piston is prone to skirt cracking at the intake window and should never be ran up or past 40 hrs max. I prefer 25 hrs.
I just bought a 23 YZ2350 and at first, my breather hose spit lots of oil on that break-in tank of fuel, along with a little exhaust smoke. I thought something was wrong with the bike. It has about 6 hours on it now and may drip a single drop after riding.
The bike is jetted a hair leaner than stock, and I am using 927, but I am not riding nearly hard enough for that oil because of the high flashpoint, I have lots of spooge. First few hours on bike were all trail riding which the YZ250 isn't made for. I lugged it too much, only the last couple times have I taken it to the track and ridden it hard. I am thinking of switching to Yamalube because of the lower flashpoint, unless there is a better oil in that 200-250 flash point range.
Great info here. Thank you guys. Ive always been a Yamalube R guy but HATE the splooge. You guys running Super M, do you not experience the splooge mess/drip?
My YZ250 had zero spooge on Super-M... and maybe an odd drip out the PV breather every once in a blue moon while sitting in the garage. The biggest factors affecting spooge are your jetting and your riding style/conditions. If you have the bike jetted crisp and are a decent rider always on the pipe on an MX track, it will never spooge. On the other hand, if it's jetted rich and you're a novice rider trail riding in tight woods, there will be massive spooge.
A full synthetic like Bel Ray or Spectro will minimize the drip. Yamalube died in the 80's.
Belray MC1 good stuff? I don't race, but I also do not trail ride or lug the bike anymore. The 927 was splooging up too much so I am trying to find something in the middle. My mechanic recommended Klotz super techniplate.
Klotz is a dirty oil. MC1 is old tech and a 50:1 min.It's the original 100:1. Go for the H1R or Spectro Platinum.
Klotz is a castor based oil, just like 927 and yes, it is dirty, especially if you don't have high combustion temps. Castor oils in general will gum up power valves and your muffler packing if you are not on the pipe and/or not doing frequent rebuilds. Lots of people love the very distinctive smell of Klotz. I find it somewhat gratuitous and overbearing, like they dumped a bottle of perfume additive in.. LOL
The original Golden Spectro is a semi-synth petroleum blend. The only full-synth they make is the SX2 32:1 Platinum FS.
Super-M is a semi-synth petroleum blend, but it burns very clean when jetted properly. In my YZ125 and YZ250 I tried switching to K2, thinking it would be better since it's full-synth and actually has a lower flash point, but for some reason it did not burn quite as clean, all things being equal. Super-M also has a very nice price point relative to comparable oils.
I've been on the Motul 800 kick for a while now. For having such a high flash point it sure does burn clean. It is also a very expensive oil. You have to figure, compared to Maxima, Motul is shipping from France instead of CA, so that's going to up the cost.
Thanks for the helpful info on this! I'll steer clear of the Klotz as well. I know 927 is good oil, but the MX track I ride on is pretty small, so I cannot ring out that YZ250 enough to be using it. I'm actually in the process of stepping down to a 125.
You all have any opinion on Yamalube? A bunch came with my bike when I bought it, I havent opened it yet. (I'm still at 30:1)
Yamalube will get the job done. Can't say it doesn't provide good protection. It was always too wet/dirty for me. Back in the day I ran GS but that is a 40:1 min. oil. Always ran it at 32:1 anyway and never cleaned a power valve in my life. With the Spectro Platinum the parts look they came out of the diswasher.
That Klotz has a high flash point as well. Many other options than that for your primary riding environment.
I'm going to look at the GS synthetic! I looked up regular GS and I recognize the bottle, that is what I put in my KX60, Cr80 and YZ125 back in the early 90's, it was good stuff!
It's all a bit confusing. If you want the Spectro full-syn you don't want the GS you want the Spectro Platinum. GS 40:1, GS 32:1 SX2, Spectro Platinum 32:1 SX2 in the same blue bottle.
I ran GS sometimes as a kid. If I was to smell a bike running it now it would teleport me right to 1984..lol

Picked up some Blud pre-mix and wanted to share info I got from the dealer. The flash point on this oil is 190 so looks like it's right there with Motul 710/Belray Si7 and is full-syntheic. Found out about by following Jared Lesher racing his YZ250 in the 450 class!
Let us know how it runs.
What’s the big deal about flash point and what influence does it have on our purchase choice and riding style?
I was previously running Maxima 927 which is a castor blend and a high flash point. My bike was spitting a lot of unburnt oil even after jetting leaner, but I found out it was due to my riding style. I am not ringing my bike out nearly enough for that kinda of oil. 927 is for racing, not lugging. I have stains on my garage floor to prove it lol.
