Metal Pinging Sound.

08FXSTI

Member
G'day all,

I am cruising around on an 08 FXSTI, not moded at all YET!!!, but i was wondering if the brains trust of this here forum may be able to enlighten me as to what a particular sound i hear every once and while may be, I would be scooting along doing about 80 kilometers and hour and when i kick it into 5th gear a sound like metal pinging happend???, This is definatly coming from the engine. Now this doesnt happen all the time and when i took it back to the dealer they couldnt replicate the sound,, got me stumped. I am not labouring the engine either,,

Any help would be good,

Johno
 
What you are probably hearing is pinging from a lean mixture and poor fuel. Use a high octane number and possibly add a fueler to the bike like the TFI to add some fuel which will also cool it down a bit too.

Don't count on the dealer replicating any problems you bring in, after the sale they loose their hearing.

Many topics on the installation and discount link here.

Are you Sure it's definitely coming from the engine???? I've heard that line from a few guys before only to find out it's a loose or broken exhaust mount or something like that. I'm not saying your wrong, just don't jump to conclusions on noises they can be pretty elusive riding 60 mph down the road.

I have the same problem, premium gas helps but it does not always solve the problem. mine is an 08 FLSTC. It sounds just like he said at first metal pinging and mine i can feel a little stubble if I do not put in premium gas. Mine is all stock as well.

Stock and hot, needs more fuel. Try a TFI and you'll be surprised.

Plenty more on the TFI here...

Check the exhaust shields, tap them on each end with your fingers and listen for the tin rattle.

If so, loosen the clamp on the end that rattles pull the shield up slightly and put a bead of high temperature silicone (red) between the shield and the pipe then tighten the clamp.

Idle the bike for a minute to start the setting of the silicone and let it cool .
