Hello fellow FZ6 lovers.
Since I bought my FZ6 I tried to catch up on previous maintenance, including fluids, filters, lubing parts and cables, ... Ever since I got it the engine was jolting under 4K at constant rpm, when rolling off or under light acceleration. Plus I could feel irregular notches in the foot rests. My first thought was to up the idle, which was under spec, but little changed. A few searches led me to believe the actual cause was a loose chain.
Checking it carefully I saw a few very tight spots which resulted in a very uneven tension. A local mechanic recommended cleaning the chain with petrol, a WD40 bath and a nice lubing after it all was dry. It was much better but now the chain was loose all around.
So I bought a torque wrench, noticed the rear wheel was misaligned, adjusted alignment and tension (around 3.5-4cm, 1.5 in) and test rode it today. On top on the unimproved notchy feel in the foot rests I now have a whizzing sound most noticeable around 70 km/h (45 mph).
Pushing the bike with the engine off isn't difficult but the chain noise is fairly loud. After double checking wheel alignment and chain alignment both seem good (chain visually, wheel with a tape meter measuring the distance of the nut to the end of the swingarm on both sides). The chain still has a few tight spots but they're now barely visible unless carefully looking at them. Sprockets were checked by the mechanic when I got advice about chain cleaning and are in good condition. I'm not even sure the noise actually comes from the chain, but it's located on the rear left side and little else seems to be moving there, save for the wheel, which seems ok.
Am I missing something obvious? Did I do something wrong? Would a chain/sprocket replacement likely fix the issues? Something else?
I appreciate all ideas, advice and contributions. Thank you all.
TLDR: chain had tight spots, seemed much better after a thorough WD40 cleaning, bought a torque wrench, adjusted chain tension and rear wheel alignment, got greeted by loud chain noise when pushing the bike engine off, a whizzing sound most noticeable around 40-45 mph, and a notchy feeling in the foot rests. What gives?
