I have a 09 Electra Glide Classic. 103 big bore, 259 cam, screaming eagle heads, V&H full system, Screaming eagle race tuner, oil cooler, and stage one air filter. My question is that I get pinging noise when I crack the throttle. Is that mean I need more fuel?

thanks

 

Pretty sure it means you need to retard the timing a little in those areas where it's pinging, but I've never used the SE tuner.

 

thanks JMR

 

Too little fuel can cause pinging. It is likely that both the timing needs to be retarded AND fuel adjusted.

Is this a new development, or has it always pinged in the same conditions?

 

it never pinged until I put the big bore kit cams and heads on. I took it to the Harley dealer yesterday and they adjusted the timing and added some fuel and its running good now.

tnx
