110 octane gas?
My friend bought a RM 125. The guy he bought it from runs 110 octane gas. Neither of us are certain what has been done (if anything) in order to handle 110. The only motor mod it has are V-force reeds. I have a '98 CR 80 and want to run 110 octane for increased performance. I was wondering if anyone knew what needed to be done in able to support 110.
Thanks in advance, Kyle

Re: 110 octane gas?
Unless your bikes are running VERY high compression ratios (meaning new piston, head milling, etc...), you are wasting your time and money. I run 93 octane in my 12.5:1 comp engine with no problem. Anything higher than what is required to prevent knock is a waste. Higher octane does not mean higher HP.

 Running 110 octane in a CR80 will do nothing for performance and makes no sense.

Re: 110 octane gas?
Octane is actually a way to calculate a fuel resistance to ignition... meaning a higher octane will combust less easily... this is necessary in high compression motors to keep the fuel from igniting too soon... in a lower compression motor, such as your 80 (or just about any other stock dirtbike, including your friends 125 without head mods) it is actually going to give you less performance if anything
