My OSSA 280i is close to 100 hours up after two years, which is not high usage.
I change the oil religiously and keep the bike in primo order but I do notice that there's a very weird low rumbly whine coming from the left side of the crankcase when under load in taller gears.
This is disconcerting and I'd like to know if its fixable?
It is not present all the time but most noticeable when the torque is loaded, perhaps its the lower e=rev range which enables me to hear it, or perhaps it disappears at higher revs, Any thoughts?
