Start at the beginning. I have a 2015 EBR1190SX. Tips & 44t rear sprocket with the correct race ecm.
I have a weird thing happening. Between 4700-5000 on accelerating I get what sounds like a pinging sound. I run 93 octane gas. Also tried octane booster with no difference.
A while ago I had to end up using 89 octane(Broken pump). Well about 10 miles later the pinging all but stopped!!!
Since then I've run at least 4 tankfuls of each, filling when tank was very low. With the same results!
I'm sure it's pinging but why does lower octane help stop it!!?? I've been riding for 47 years & worked on bikes when I was younger. STUMPED!
