2006 f650gs engine noise
Hello all!
I recently purchased a used 2006 F650GS (date of mfg 11/05) from the original owner with 9,800 miles. I've now noticed and engine noise/knock. It could have been there previously as my test ride was very short. This occurs at 2500 through 3500 rpm, under load, only. I can't seem to replicate the noise while on the center stand. It's difficult to tell where the noise originates. I've used a mechanics stethoscope to no avail. The engine seems to run flawlessly other than that noise. It has good power and accelerates well even through that rpm range.
The previous owner said he did regular oil changes as they were free to the original owner. The oil level is full and the oil appears clean. The bike seems to have had some regular maintenance as the chain and sprockets are newer. But he did say it's never had the valves adjusted because it didn't need it until 12k miles, which a Haynes manual confirms. I put in some octane booster to see if maybe I got some bad gas, but no change since adding. Any comments or suggestions would be appreciated.
Thanks.
