Kato i believe we all cum from monkeys 
Interesting read about the oils,i see he didnt test motul, 50:1 is safe as houses if your jetting is correct,i have run 60:1 and 70:1 in the past with correct jetting,just remember this rule,the higher the RPM turned the more oil you run in your fuel,when my IT250 is rebuilt i will run it at 40:1 motul full synthetic a lot of older folk just never got with the changes in times and my father who is an excellent mechanic is one of them,he grew up with castrol mineral oil as that was all that was avalable back then,he swears by it,i myself wouldnt oil my chain with it i find it crap, he likes the good old 25:1 mineral as he always says,well we now have a hell of a lot better oils now that can be run safely(IF YOUR JETTING IS CORRECT) up to 60:1 70:1 i have run yz465s with motul 800 at 65:1 at WOT(WIDE OPEN THROTTLE) for over 1 hour at a time with out even a hicup,however its the shutdown or throttle chop thats the killer,we would run a seperate cable to a bar mounted lever that would operate the choke so after a long high speed run just as you are about to chop the throttle you would pull on the bar mounted choke lever that was a safe way of not having a seizure,i believe that a lot of the Baja desert races in the states run a similar set up to stop there 2 strokes from seizing when the throttle was chopped....BB

Wow LOL.  Either how....I was running H1R and went too Bel Ray S2 when I killed my engine.  I'm guessing this was part of the issue.  Amazing you could run 50:1 on it with out a problem!  that's great.  I hate the price of the H1R, but the dealership i think is selling it for a killing.  Costs $23 bucks a quart (hence why I switched) here. 

I buy H1R for $60 per 4 litres.

I won a bottle Motul 800 the other day and will have to try it at some stage.  It is based on esters!!!  Not sure what it means exactly but they say it is better!  Don't know what ratio's are recommend for it though.

Last time I bought 2 stroke oil I purchased a 25L drum of Morris Oils 2Hss Ground force Semi synthetic. $180 + GST. Including Gst, It's still less than $10/L.
I would've ordered some drums of Penrite Hi-Per, but I ran out of cash. That stuff is great. Burns clean too.
This Morris stuff isn't as clean, and makes it hard to read the plug. Either that or my crankseals are on the way out!
For us Aussies, Keep an eye out in Supercheap Auto for Penrite Hi-per. Was cheaper there per L than the local rep was willing to do per L, even if I purchased a 20L drum!

I saw some of that and wondered if it was any good. You find it ok? I'm running some Castrol Active something or other. Seems ok and burns clean. Got it at the pervayor of quality merchandise that mentioned

[Griffo]

Ouch! That is the dear sh_t isn't it!

When I had a perv up the pipe ole, after running on Hi-per at 20:1, Everything was clean as a whistle, and it was all nice and wet with oil. Very clean!
Never had a problem with oil fouled plugs either.

I'll be ripping the bike apart soon, so I'll let you know how this 2HSS is going...

Two types of activ something or other, One ( i got) $14 for a litre, other $35 a liter. Just got a liter for that days riding thats on the vids i posted. Want to try the Yamalube. BB said 35 to 40:1. I went half way and have been running 38:1........seems ok, need to figure out how to do a good plug-chop and check it.

Oils is an interesting topic, everyone has their own opinion, I run Motorex cross power 2t, buy it in 4l $90 not cheap but it says it can be run up to 100:1
I mix it at 50:1 in all my bikes and it seems great, smells good too! I tried H1R but it seemed to drool a bit, I had the top of the wr500 motor apart not long ago and the piston and bore look good.
BB. I have always thought it would be a good idea to set up a remote choke on the WR, the bike runs great under power but its the throttle chop after a good WOT run when it seems to sound lean and give a little detonate. I have read an old article on yz490 that was done up for desert racing and that had the remote choke on it.

I did try 32:1 on the Yamalube. But the bike ran better on 24:1. So I thought, fuckit! 20:1 is easier to mix. Plus my crank bearings have so much play in them, it's not worth measuring how rooted they are! But still no noise. Turns over smooth, without a plug in that is!

[Griffo]

Remote choke was only for desert runs, at WOT. Choke was used to keep motor cool in an attempt to stop it from melting down!
Better off modifying the carb to run an adjustable power jet.
My 465 Hardly ever used to ping, untill I got it out in some deep sand at the RDR. That loaded the motor right up! sh_t it pinged its head off then!

dmc12d...i agree motorex is my second choice of oil its great,i dont buy it as the rep up here that sells it is a c__khead so i wont buy it,i mean not just a c__khead he has a plaque on his wall saying that he is a c__khead,mate if there was c__khead comp of the century this guy would win by a country mile,great oil though

[Bigbird]

Hey Griffo try running less oil in your fuel if your pinging,i have a new nickname for you(GREASY)sh@T i am surprised your old IT can even fire that oil/fuel at that 20:1 you run or maybe i should call you PUFFING BILLY i bet there is no mosquitoes near you when your riding

[Griffo]

It Loves the sh_t!

[bholmes]

That was a really great article you put up there Jock.  I much appreciate that.  I was actually starting to lean towards yamalube but that settles it! My only gripe with yamalube is back in the day my cousin used to run it and I hated the smell of it!  Oh well...I won't be riding behind the YZ so I don't care!!
