No Mods..at least not to the engine. I suspect it's probably normal but I have an appointment at the stealership Saturday morn. I'll let you all know what they say....but the service writer did tell me they are noisey by nature.
Either a 2 bro or twin Jardine w/ a PCIII is in the NEAR future, but I don't want to give them an excuse if it is internal issues.

 

Well.... I picked it up tonite from the stealership, they said it is a slight bit more noisey than they usually are. They contacted HC about it, They claim they made a "computer adjustment", So they opted to have me ride it for 150 miles or so, then when they do the 600mi service they will re-check it. It DEFINATELY was a bit of detnation, they verified it, so I'm not crazy. Whatever they did , made it slightly quieter..alot less detnation type noise. I did'nt notice any power decrease so I'm not exactly sure WTF they did.
