Grinding/Vibration Type Noise Coming From Engine
 

Howdy,

I have Fuel Injected 06 RKC that I've had for a year with 9200 miles on it. I recently noticed an odd noise coming from in front of the engine when in second and third gear at about 3200 - 3500 rpm. It almost sounds like a bearing is going out somewhere.
I've checked for loose parts in the fork area, tire, light mounts, windshield, rocker box covers, floor boards, Exhaust Pipes and anything close to where the noise is coming from. The front engine mount was replaced with the new upgrade about 5 months ago. The spark plugs look in good shape.

I checked the motor oil and tranny oil and I didn't see any metal shavings. I did not take off the cover to take a look at the cam tensioners.

The only engine mods I have are SE pro slip ons, K & N filter and a Dobek/TFI Fuel Control Box.

Anyone have any ideas to what to look for ???

Thanks,

Ray
