BASS ACKWARDS!!??

For those of you who aren't Norwegians that is a term for using the fish to catch a worm. After the great diode non issue-today I mounted new exhaust then thought it prudent to finally look at the plugs thinking it might show something related to jumpy tach/miss. The suspect front cylinder's were a nice/normal tan whereas the rear's had a heavy white deposit around the electrodes!!?? After cleaning them I did a quick round-the-block(getting dark/temp 50F),no apparent miss but tach still jumpy. Will ride more tomorrow.

Jumpy tach a lot of times is a bad ground, check all your grounds and you battery cables to make sure they are tight and clean.

I already added engine/RR/battery link and took tach apart to check wires. I'm wondering if The dirty rear plugs were the cause of the miss and somehow effecting the tach. "When you can't find a log clutch a straw!"

the tach runs off the electrical pulses to the front ignition coil.

Rear jug has nothing to do with it, so you have possibly 2 seperate issues.

The ground is what is pulsed on the front coil, so a loose ground will cause issues and cause the tach to be irratic.

It is also possible that the same ground issue is causing your rear plugs to look the way they are, but not as likely.

I did clean the front coil mounting points but perhaps need to give it a ground of its own.

Check ALL grounds....Battery ground to battery box, battery box to frame, and frame to engine are the 3 main straps, but any bad ground connection in the wire harness could contribute to this and may other symptoms.

MISS BECOMES A WHINE?

No-not a beer serving Wench becomes a Zinfandel. All the jumpy tach/misses were a wire issue. When I replaced bad ignition there were 2 brass & 7 silver female connecters in the 9 wire plug(obvious replacements). Those 2 aren't held in the plug like the originals and so the black/white worked its way loose. I pushed it in all the way w small screwdriver and all fixed. Went for ride today and am very happy that the problem was such a small thing. I love to listen to happy engines but then start wondering what are normal VN sounds. At 55-60 I hear a gear sound like 1-2-3-4/repeat-a bit like the hoglie potatoe cadance. Most bikes have normal noises-the GS Suzies had lots of primary gear whine. My hearing isn't too good-Cicada lives in right ear(tinitus) so maybe it's just wind in the disk holes. The worry-wort part of my brain thinks-final drive/front bevels/primaries/wheel bearings/Troll in tranny?? Perhaps this is why many people fit loud pipes. My Futura sounds terrible at idle when hot but nothing is amiss(completely apart last winter for valve seals). Very happy w how it runs now. I'll drop forks tomorrow to improve understeer.
