Throttle Vibraton/jerky rev counter

Hello SV Riders,

your advise please..

last Sunday i inspected the magnets on my bike (2007 with 65000 kms on the clock) all was in order with the magnets, none of them had moved nor broken.I did however notice that one of the coils was much darker in colour almost black in colour compared to the others .
i reassembled and went for a ride this morning.

I have now noticed that the vibration from the throttle is worse that it has ever been and now the rev counter is playing up, the rev counter seems jerky as i accelerate, this has never happened before.
I just cant figure out what has gone wrong with the bike since i removed and replaced the cover to inspect the magnets.

Any help will be most welcome

regards Shamless

Make sure the crank position sensor plug is all tight and clean.

....at worst case, if the plug isn't the issue, maybe there was some flotsom in there that has got stuck on the crank sensor, or even
on one of the signal lugs on the outside of the rotor...

Next would be doing some resistance and voltage checks on the stator to see if that blackness is a sign of a dying rotor.....

You said the magnets are good, but, have you gone down the path of JB welding them ? I check mine some time ago, and they were perfect, but
not too long later, and all but one had come loose.....

One owner..... 313,000kms and counting...
