I hit 106 today and still had tack to spare. Not a lot but I'm pretty sure that I could have gotten up to 110. My bike is still totally stock. I'm believe 100% that this was due to the temperature of the fuel in the tank. I can't back that up at all with any kind of explanation but I'm sure its a fact. On several occasions now I've put cool fuel in my bike and notice that I'm doing the same speed at 3k less RPM s. I'm still running 14t front, not shims, stock muffler, uncut fender, I didn't even have my bungee cord on today. I would love to hear any hypothesis to prove or dis-prove my theory. Try it yourself. I'm not condoning going over the speed limit. That would be illegal and unsafe. What I'm saying is take your lawn mower gas can and put it in a freezer for awhile and then put it in your tank and see if you can tell any difference. Be careful not to contaminate the food in your freezer and always was off the counter surface and all of your cooking utensils when preparing poultry or fish or Sal Monella may come pay a little visit to ya and kick your guts in.
