iam after opinions from engine builders here,
is this excessive carbon build up?
iam chasing a engine knock (iam thinking ignition knock) at idle, when you first apply throttle it knocks,
ONLY WHEN FULLY HOT, soon as you stop for 15secs itll go away till you get it fully hot again,
ive checked so far:
piston pin (perfect fit)
rod bearing play (solid)
flywheel bearing play (solid)
its been run on PREMIUM since ive had the bike (700km its done on premium) and i found out today premium is a NO NO in low comp ratio engines, cause this be the result of using it????
