HC piston on a 944 SS carb: what sparkplug use?

#1 (**permalink**) 08-18-2005, 05:39 PM

A pal of mind has a 900/944 SS with HC piston.
he uses OEM plugs.
When he accelerates a little bit fast to the throttle, a kind of sound like "click click" seems to come from the heads. (In french, we call that "clicketis", unwanted detonations in the head, but i don't find the word in english)
Could it be relevant of a bad choice of plugs?

if you're talking about pre-detonation, higher octane gas should do the trick. Also, did your friend retard the timing on the bike with the 944 kit?

My friend didn't retard the timing on his bike.
Pre-detonation=cliquetis
