Well, there you go. elsancho runs MC-1 at 50:1

We only sell the Spectro, so my goof on the MC-1 is a lack of knowledge of the product.

 

If you want to learn more about your R, especially the motor, check out macdizzy's web site:

Everything you ever wanted to know about the R and 2 stroke motors, oils, mixtures, etc. You can even download an '86 owners manual for an R.

 

50:1 with MC-1 is crazy. i run 32:1 and i have perfect jetting and awesome performance. one tome i ran 40:1 and that was way too hot by the look of the plug

 

i have a good spin on this fuel mix thing..i run 50:1 in both my 250r's and they still smoke.i run both bell-ray and klotz mainly klotz with 89 to 93 octan ...and dude u made the right choice 250r's rule the world

 

on teh back of the bottle is says to run mc-1 @ 50:1

 

thats wak

 

i know it is crazyhorse a frined of mine brought it up and asked what mix im running because they both smoke and i was like 50:1 with klotz and 93 octan and my jetting is right on. im not going any higher with my mix

Crankcase Oil--Castrol 10W-40

 

NGK BR9ES and BR8ES
Spectro SX (I think it's SX)Fully synthetic mixed at 32:1 with 93 octane.
Can't recall the oil at the moment, it comes in a white bottle and I think it's 80W

 

50:1 with Amsoil 2000 fully synthetic. And no, this is not too lean with this oil. This is what the bottle recommends, and there was plenty oil dripping off of the crank when I tore down the 86 motor this winter. Proper jetting will eliminate the engine running too hot.

I also used to run Golden Spectro @ 42:1 on my 330R. It also had oil dripping off the crank, and still had 75% of the cross-hatch pattern on the cylinder even after 2 seasons of duning.
