I am trying to determine the reason for the little weird noise I am hearing from my Meanie. I am familiar with all the weird noises it normally makes, but I thought I heared it first after I dropped the bike... or I just started noticing it because I became paranoid.
In either case, I wonder if what I am hearing is the spark knock. (If so, I'll just do a simple resistor mod to try fixing it). I debaffled my stock exhaust and marbled the reed valve several months ago. I'll describe the sound, you tell me if that sound like spark knock.
It's audible when idling. Not all the time, but most of the. It's also audible (a little louder) when I add a little bit of throttle when idling. I can't hear it while riding, not loud enough. At idle, it sounds like faint clicking rather than knocking. Click-click-click-click-click... The sound seems to originate from the left side, close to the rear cylinder (that general vicinity).
Doesn't sound bad at all, but a little concerning. What do you guys think? Is this spark knock?
