PolyKarbon Posted March 23, 2005 Report Share Posted March 23, 2005 Ok ok, I know I need to run race gas if I run 19cc domes, but why exactly do I have to? Can anyone explain what happens if you dont rune race gas? I had the shee out the other day and it *appears* to run fine except that it wont shut off with the on/off switch. I cleaned the switch out really good but...wtf? Quote Link to comment Share on other sites More sharing options...

PUSH THE THROTTLE Posted March 23, 2005 Report Share Posted March 23, 2005 (edited) I have a local gas station that sells 110 at the pump for 3.59. You should look in the phone book and call all the oil companies and stuff that are in it they should know where to get it. If you run to low of octane your gas will ignite under pressure and not under spark wich will cause detonation. Detonation is like bombs going off in your cylinders and it will tear them up quickly. You should hear detonation. What kind of compression numbers are you hitting? Edited March 23, 2005 by PUSH THE THROTTLE Quote Link to comment Share on other sites More sharing options...
MotulMonsta Posted March 23, 2005 Report Share Posted March 23, 2005 Your kill switch is an open circuit. So lonk as the contacts don't touch, Bike will run. Perhaps you have a break in the wires somewhere or your swich crapped on ya. If your detonating...you'd here it pingin'. By then, it may be 2 late. Any Motorcycle/race/track shop should have some good VP fuel on hand. Quote Link to comment Share on other sites More sharing options...

This causes harmful, and possibly fatal, motor malfunctions. Quote Link to comment Share on other sites More sharing options...

y2kbanshee9187 Posted March 23, 2005 Report Share Posted March 23, 2005 I know around here(Ohio) we can get race gas at any Citgo gas station for $3.99 I think Quote Link to comment Share on other sites More sharing options...
PolyKarbon Posted March 23, 2005 Author Report Share Posted March 23, 2005 Well I think my shit might be pingin but I dont really know what it would sound like anyway. Quote Link to comment Share on other sites More sharing options...
BansheeBrian Posted March 23, 2005 Report Share Posted March 23, 2005 The sound will definetly be an unmistakeable PING.You will know when you hear it.Any sign of minute grey specks in your plugs will indicate a bad PING.It may be too late then. I don't think anyone has the balls to post a sound bite of a detonating shee.It take quite the dedicated member! Quote Link to comment Share on other sites More sharing options...

dlnoss Posted March 24, 2005 Report Share Posted March 24, 2005 Sometimes, it's easier for someone else to hear detonation. I've heard other people's Banshees detonating from a distance but they didn't notice it. Quote Link to comment Share on other sites More sharing options...
Ducman Posted March 24, 2005 Report Share Posted March 24, 2005 Running too low of octane to support the amount of compresion can result in preignition, pinging, run-on, and detonation. These symptoms are all related but different. High cylinder pressures create high temperature making the fuel want to ignite before the spark fires. More octane increases the temperatura at which the fuel will self ignite (flash point). If you are running pump fuel with 19cc domes, you may be experiencing run-on if your kill switch was working fine before. If you take your shee out for a romp you may get to hear some pinging followed by detonation. Pinging would sound like a couple of marbles boucing around inside your pipes.
