Relax chief, I used to have a Vulcan myself, I am not knocking them, even though they knock, lol. Seriously though this is a common issue with them, though I know there are plenty out there that run fine on 87 octane.Originally posted by FatTortoise+Mar 1 2004, 02:14 PM-->QUOTE (FatTortoise @ Mar 1 2004, 02:14 PM)<!--QuoteBegin-dIESEL600HOW DARE YOU SPEAL ILL OF DA VULCAN!@Feb 29 2004, 05:55 PM
let me guess, you have a vulcan...
I have NEVER had a problem with pinging on my Vulcan, maybe because it is a FFV.. *shrugs*
Sounds like spark knock pinging to me, it is much more common in warmer weather and happens with the engine under load (accelerating, climbing hills, etc.)Originally posted by gtx2000@Mar 1 2004, 03:08 PM
How can you determine if it is pinging or there is something wrong?
Mine just starting doing this in the nicer weather it seems bad though. I mean when mines doing it it seems as rod knock but it only does it under load and not when idling when revving the gas?
Nooooooo dont use 87. That is why it is knocking. The burning ratios are off for combustion are off. Use PremiumOriginally posted by barnz67@Mar 1 2004, 10:55 AM
yes I have vulcan, so this rattling /knocking /pinging sound is from the gas. I've been running regular 87 octane. So I have to burn this gas out and try premium huh?
