Keep a jar of the thickest, stickiest grease you can find with your oil.  


Obtain a new tachometer seal, install it. Then stuff the hole full of this grease.
Clean the tack area up after you push the cable in forcing grease to ooze from the area.


Every time you change your oil remove the tachometer cable and repeat packing the cavity with this thick grease.


I use Kendal high temperature wheel-bearing grease.


No more leaks from the tachometer seal.

Quote from: TwoTired ...

"I should note that a low, smooth idle follows:
All cylinders having the same compression numbers.
All cylinders have their valves adjusted perfectly.
Can chain tension correct.
New spark plugs
New points, condensers, and the timing advance working properly,
The point gap, and spark timing are spot on.
All carbs are clean as new, and every internal orifice, whether for air or fuel, flows the same between each and every carb.
Brand new stock air filter.
Original exhaust with no rust holes. (or mouse nests)
A consistent and equal temperature for all cylinders."

WD-40 (Water Displacement recipe #40) Took them 40 tries to get it right. It was never meant as a lube but people just assume. My uncle used to spray the inside of his boat distributor cap, never missed a beat. It actually works as a fish attractant as well

A drain bolt should either be in & tight, or on top of fresh oil can/bottle.   This eliminates the 2 AM panic wake-up "did I tighten bro's drain plug before he left?" & the (old timers) where the @#$#@ did I set that  @#$#'er..... G

Cotter Pins are great, but not very reusable, I've found Hitch Pin Clips work great on rear axles, and torque links, etc.

When working on a motorcycle, never be in a hurry to go for a ride.  While riding a perfectly tuned motorcycle, never be in a hurry to get home.

i so love this can i use it in my sig

Not mine, but....

cotton cord, or a tampon can be shoved between fins to soak up slow leaks.

re: CB750 cylinder head removal:
This is prompted by a problem posted in another thread. There are 16 head nuts and 4 screws. The screws go down the center from side to side, residing under the 1,3,4, and 6th rubber puck. When disassembling these should be removed first. A slight tap with an impact should do it. Often not even that, a T handle #3 phillips is good.

If you remove the head nuts first, all of the relief pressure of the head will be released into those 4 screws and they ain't never coming out. Which is the purpose of this post. Don't get in a position where you've stripped the tops off these screws, trying to get them out with the head nuts off.

On reassembly, put the 4 screws in first and snug them down in alternation. This draws the head into its ORings, dowel pins etc, letting you know everything is OK. Then put the nuts on per manual, alternating and sequencing. Having done that the screws will now be loose again, so you'll need to snug them down some more to keep them from rattling around and maybe backing out. I've often threatened to just take them out and leave them out. But the holes may fill up with crud so I leave them in.

Just found this in another thread, good one dude.

Don't kick-start your bike to impress onlookers unless you're positive you can start it by the third kick. 

Good one.  When i ride with my buddy and his magneto harly i wait until his 10th kick then i one kick mine.

I'm sure I should have realized that brake cleaner would take clear coat off aluminium.... oh well lesson learned.

so does carb cleaner, if you let it sit for a bit.

If replacing fork oil, be sure to put the bike on the center stand before removing the top bolts holding the springs.  Failing to do so will result in large 23mm bolts being launched into the face of the person removing said bolt, and may result in the front of the bike dropping 6-8 inches suddenly, leading to a tip over situation.

I only mention it because I saw some total jagoff make this mistake in my alleyway with a bike that looked sorta like mine.  What a rube.

Same thing will happen with the bike only on the center stand, because all of the weight is on the stand and the front wheel.  You have to raise the front with a jack or suspend from the ceiling to get the weight off the front wheel.

This may be more personal opinion than a nugget, but a day in the shop isn't complete without a blood blister.  

I always feel so much more satisfied after spending time in the garage when I take my gloves off and see a good blood blister on one of my fingers.  It means not only that I was wrenching hard but that I was so focused I didn't even feel the pain. 

The older I get, the more calloused my hands get, and the fewer blisters I get, but I appreciate them when I do.

I've always said that! "Its not a good day in the shop if I don't draw blood".  I have a sign I bot from a garage supply place with "The Busted Knuckle Garage" and the logo of a finger with a band-aid on it. The legend underneath says "Repair and Despair Under One Roof". All tongue in cheek of course, but it's how I feel.

[Skonnie Boy]

On a somewhat related note, I don't feel like I've really accomplished anything unless I'm just covered in grime and oil afterward.

My Dad (rest his soul) used to say that if you didn't have a few parts left over, you didn't do the job right.

What was he thinking?

Hey now!  Maybe that slips by when you're selling drugs to people for your day job, but when they're buying expensive, curdled, fermented and aged products made from the mammaric expressions of various four-legged creatures, they expect your hands to be spotless!!

Oh Geez Gordon, your such a puss. You're supposed to wear your spandex latex, er nitrile gloves AT WORK so that mammaric curdling and fermenting stuff won't dissolve off all that manly grease!  There's only one other natural product I know of that will remove it better 

[captaincrash80]

Never take advice from someone who says "I knew a guy who's brother had one of these, lemmie take a look at it"

If you're buying a used bike and the owner is too eager to say "There's nothing wrong with it and it runs PERFECT" he's probably lying.

 WD-40 was not developed to be a lubricant . It was developed to be a water displacement.  Hence the name-
          WATER DISPLACEMENT  # 40 FORMULA  ( WD-40 )
