This post is for all with the pulsing vibration in second gear at about 25-30 mph.
I think it's the change of tyre.......
I've changed sprockets and chain and cush drive rubbers and it's still there.
OK, an exhaustive search suggests that this often happens after a change of tyres... exactly the same symptoms.......
Given there's no play or a roughness in the rear wheel bearing, I'd suggest that it's a sensitivity to a change of rear tyre.
This seems to be the common factor in all such issues.
Me, I changed from the factory Metzler Me 880's to the ' new,improved' 888's.Others seem to have similar issues after doing this.
Might I therefore humbly suggest that this bike doesn't like these tyres?
If anyone knows better, I'd appreciate hearing from them.
I'll let it rest for now.....it's not in fact a big deal...just a minor irritation.
If I get really peeved with it I'll change again.
