are you really sure about that? im just asking i dont know, but i do know this in some cars it will make it faster alot of cars have knock sensors and the computer will advance the timing untill it hears a ping and then back off 2degrees for best performance and with all the technology going in todays bikes i wouldnt doubt it if my bikes got that now.. doesnt matter i did the tre mod on my bike and is in full advance first three gears. i might have to agree that 110 might not make a difference but unless i try it ill never know

 

ive ran them all..they all seem the same to me so i use 87 so i can get the most riding for my $$$$$$$$$$$$$$$$$$$$$$$$$

 

i try to get the most for my money also so i just run kerosene in my bike. Seems to make the bike backfire and die but damn does it help my headstand on the front fender wheelies...............

 

what the hell do you consider to be high compression?? i know the R6 has like 12.4:1 .....thats pretty phuckin high

 

this is going to stop doodle.....

 

ill stop when he stops whoring my threads and making ignorant comments to EVERY post of mine...

 

no your going to stop right now and so is he i have spoken with him and he has agreed to stop

 

Absolutly Incorrect. Modern street bikes do have somewhat High compression 12.5:1 etc., but they also have a short stroke. Thus no detonation and high rpms. High octain fuel 100and up will not add any power what so ever, in fact it will burn slower and you will loose HP. Unless your bike is detonating, which is very difficult to do in modern bikes or you switch to an oxiginated (sp?) fuel, Like I run in my race bike. You will loose power. I use Tracktek TT114. By the way

 

All fuel does is burn. On my buddies dirt late model race car we used 112 octane. But it also has 14.5.1 compression ratio running 9,000 rpms in a small block.

No matter what motor you have all the octane you need it what is required to keep the motor from detonating. When you go a lot higher in octane rating than what is required all you are doing is losing money.

 

what he said......the best way to make pwer is to use the lowest octane you can that doesnt allow the motor to detonate

 

usually a sticker on your bike or a page in your owners manaul recommends a certian octane.

 

pretty much.....you get the idea

 

[QUOTE=crzy954rr]Absolutly Incorrect. Modern street bikes do have somewhat High compression 12.5:1 TRUE they also have a short stroke.TRUE Thus no detonation FALSE and high rpms TRUE..(but not all the time) . High octain fuel 100and up will not add any power what so ever, in fact it will burn slower and you will loose HP FALSE (although it sounds good as long as the fuels lower heating value is the same, with gas station fuels they are about the same, there is the same energy in the fuel. Now if the timing of the engine is too advanced or the mixture is lean for the given compression ratio(CR is a functoin of head volume, bore and stroke) then the cyl will develop hot spots on the piston, cyl walls or head/valves. When the piston starts to compress the intake charge by nature the mixture will become hotter- same energy smaller volume so the temp raises- the mixture could then be ignited by one of the hotspots in the cyl acting just like your spark plug, when the spark plug sparks it creates two flame fronts in the cyl. when the flame fronts collide you hear a "knock" or a "ping" both are harmful to your engine. Now under low loads.. ie cruising down the highway the bike has such a low load on the motor that 87 would work fine( lower cyl temp), but under heavy accelration- highload the engine would work harder and the hot spots would ignite the mixture, thats why every one is talking about "flashpoint" I hope this makes sense, and helps clear the air.. believe it or not Im an engineer and engines are my specialty ..
