Duduglanza Posted June 25, 2015 Share Posted June 25, 2015 Im not sure of this but when im accelarating i sometimes hear some knocking/ping. I have forged wossner pistons and by them selves they already make strange noisestill they heat up but its common as i know others. How can i be sure the engine is not knocking/pinging? Should i retard ignition by a bit and see if it does it or any other method? Quote Link to post Share on other sites
H_D Posted June 25, 2015 Share Posted June 25, 2015 if the engine is really knocking then your knock sensor should pick it up.It may be gearbox related. Quote Link to post Share on other sites

Duduglanza Posted June 25, 2015 Author Share Posted June 25, 2015 No im noy using detcans altough im doing a pair right now.. The knocking noise loud enough to hear it by ear while reving. I might be worrying for nothing as it only knocks for a second in the 3000rpm range. Quote Link to post Share on other sites
