Start with the easy stuff, clean and lube up your chain. A couple drops learning to ride shouldn't be a big deal and shifting with out the clutch really isn't either if you slightly let off the throttle to let the gears synchronize enough.
Yea i had it up yesterday when cleaning and lubing. It spun fine and there was no noise coming from the rear wheel. What would you look for when checking wheel bearings?So I literally just joined this forum, but after reading this I do want to ask. Brushing sound could mean a different sound to many readers. Do you have a rear stand thatll allow you to lift the rear wheel off the ground and be able to spin it freely? Just want to be safe and make sure this sound isnt possibly a wheel bearing. These do fail and if it is this then you need to get it replaced asap.
After cleaning it does look like the teeth still have a bit of flat on the rear sprocket. I think there's still quite a bit of gunk between the chain and the bit of plastic above the swingarm so that could be a source of noise?From what you say about when it does it makers me think it's chain and sprocket noise to me. I'd slap a whole new set of chain and sprockets on there as your rear sprocket is completely goosed so your chain wont be good either.
I know my Aprilia makes a lot of chain clatter when slowing down and changing down gears. It's the chain catching on the plastic guides around the swing arm pivot area. Was quite alarmiong first time I heard it but I'm used to it now.
Absolutely. And whoever said that sprocket was OK one month ago shouldn’t be working on bikes. Of course, the sprocket may have nothing to do with the noise in question, but it needs replacing anyway. If the chain has been in use on it for any length of time, that should be changed as well.That rear sprocket should certainly be changed ASAP.
You need to change your 'mechanic'.On the rear sprocket, the mechanic inspected it today and said it looked fine and didn't need replacing. I showed him the photos and he reckons it just looked worn due to the dirt that was on there.
