I run 40:1 with klotz.
A boost bottle is not necessary. Does it work, I don't know. I haven't seen anything to prove it does but nothing to prove it doesn't. The only thing is its heavy so it shakes a lot. The shaking rips the intakes. If you want to keep it, then by all means do that. Just keep an eye on the boots. Now back to the oil, klotz is a quality oil, so I don't think that its not doing its job. I use ST never had R50 available to me. But 32:1 and 40:1 are really close and 32:1 is the most common run ratio
