I've had a gl650i for a year now and have been restoring it a bit at a time to get it into proper riding shape. One thing I have noticed since I got it is that it is quite noisy inside the fairing while outside it's pretty darn quiet. It appears that the noise inside is mechanical. (When I squeeze the clutch at speed, the rpms drop and it gets pretty quiet.) For a while I thought it might be the tach cable so I replaced it and not much happened to the noise level. I have adjusted the valves and that improved it slightly.
Is the high noise level normal or should I be looking for another cause?
