Remove the OMP, make a aluminum block off plate, use shorter bolts to reinstal or you can damage the front cover. The add 2 stroke at each fill, I do it on mine and am very happy with it, I use Amsoil in the engine and now it goes 7500 miles without using any oil at all.

1 oz of quality tc-w3 2 stroke per gallon of gas some people swear by MMO, but i would personally use 2 stroke.

If you use 100:1 ratio you will be safe

80 to 100:1 is safe, 50:1 for a race motor

I leave the OMP connected and add 8-10 oz. of 2-cycle ( or MMO or Idemitsu) in each fillup.

Watch your oil when you premix, I find that that it is time to change it when it starts getting higher.

Standard measurements, oz/gal, comes out to 128:1. Metric comes out to 100:1. In that range you're fine. 50:1 in a race motor? Fouls plugs quick and a good way to blow a turbo motor that's tuned tight.

50:1 in a high strung NA motor, never had a problem with fouling plugs. i would have never though to mix that rich, but an old rx racer suggested it.

Well, with my very limited experience so far, its great. I haven't run the car much and I'm running a little more oil than your supposed to. Engine is still on same tank as when I first started it after sitting for upwards of 7 months and I didn't wanna damage anything. So if you can find a 16 oz bottle, adding that to a 16gallon tank at fillup would be perfect from my understanding. I'm a metric person, so I don't know how many ml are in an ounce. I just know for 6 gallons I used about 300ml.

Oh ya, another thing I noticed is that its not nearly as easy to flood the engine. I was fiddling with the linkage on my carb and forgot about the accelerator pump and probably pumped the thing 4 or 5 times. Just held the foot on the floor and it fired right up. Before with the original carb it would flood out with just 3 pumps and I would have to go through the deflooding procedure.
