    Doesn't sound real good,but by the way you described the noise it reflects how an engine would sound if you loaded it up,meaning if you gave it  a big handfull of throttle while the motor is too low on revs and/or in the wrong gear ?? Excuse the comment if you are an experienced rider.

    Thats what I originally thought R.T. but its a new bike and he hasn't even changed the pipes yet so why would it be running that lean at high revs ?? From new most bikes are running lean low in the rev range not high,maybe its a combination of both problems ??

    Your welcome,another good way to avoid pinging and loading up is to flog the shit out of it right through to REDLINE in every gear all the time. The engine may not last long but it would be a lot of fun along the way and a good excuse when the missus asks you why you need a 120hp new motor.

    OK, I've been mulling this one for bit,

    As most are aware I'm on a temporary 82 Gold Wing till me Softail recovers from a bad case of Hyundia.

    Had other jap 4's but allways air cooled so tuned em with fans on high but the Wing  has a radiator and thermo fan so I let it take care of its self while I pissed about with the carbs.

    Now what I noticed was as I got closer to a good carby balance the less often the fan cut in = the motor was running cooler with the carbies equalised to each cylinders ability.

    Also we all have read endless number of posts that add up to just about any change to OEM ECM settings brings cooler running temps.

    Is it possible that only 1 cylinder is pinging and the other is OK. After all we only have 1 TB (thottle body) feeding both pots.

    Could it be that the stock maps are just wrong on what the SERT refers to as VE (individual cylinder Volumetric Efficentce).  So what I can't spell but could I be right?
