I have a DS650 with +1 MM valves 11.5:1 piston , Ported intake TM45 carb, Ron Woods CDI, and Exhaust. Should be running 100+ octane?

 

No, I doubt it. Pump 93 should be good enough...

 

50/50 mix of 110 race gas and pump premium. What elevation are you riding at?

 

I run 25% 109 and 75% 93 in my yfz but it runs fine on 93 I just like to make sure she is running cooler.

if you get to high of octain in it will just slow it down start with 93 then run somthing around the 100-105 if it seams to rev. slower then go back to the 93

 

yeah sounds good, dont forget to add atomized headlight fluid

 

11.5:1 should run just fine on 93 pump gas. We run 100 in the 13:1 engines though.

 

Don't forget about the aircraft grade blinker fluid!

 

My general rule of thumb has been: For engines with less than 10:1 compression, use plain old regular unleaded. For engines with more than 10:1 compression, use premium unleaded.

 

I was getting some spark knocking with 93 octane at 1200ft elevation around 8k rpm. Mixed the 50/50 Turbo blue 110 and that fixed the issue. Yea I need something for the headlight it always blows out wtf?

 

Sorry for passing along some bad info. This is what I ran in my 13:1 compression stock bore. When I was at 11.5:1 I ran straight pump premium 91 octane without any problems. Stock compression DSs run fine on 87 octane.
