It's a bugger when they leak oil.The design is good,the grommet compression is all that is needed to pull in the covers to mate with the sealing surface,if all is flat and true.The landing on the bolts is measured as a stop for any more (excess)grommet compression.You could machine these back a little.A finer thread into aluminium(aluminum),the cheese of all metals would be a design error resulting in the need for a thread insert.You may be stuck with needing a new cover.Refacing,you could try wet n dry sandpaper on a mirror or "flat glass".good luck.

Thanks bud.  So far, the new gasket is doing its job.  So no worries as of yet.

Hey guys, can you please tell me.  Are the rubber tank grommets supposed to remain fixed on the tank pins.  OR, fit into the frame brackets and remain fixed on the frame?
thanks

Mine stay on the frame although one of them, on my K100 did have a tendency to stick to the peg on the tank.  I glued it to the frame, and use a little bit of Vaseline on the peg.

Both of mine are on the tank - which given the state of my bike would indicate they should stay on the frame....

10-4 on that, and Vaseline for all grommet-peg fittings.
 No glue on mine yet, but I did buy new grommets and clips.

I can say this.  I got em on the frame now, and w a bit of silicone tank pops on easily and the clips are a lot easier to install and remove.
Thanks everyone.

No luck Whitetail hunting,yet.
Got busy on the waterpump rebuild.


first thing I found was PO had stripped the head on the drain plug.





I may have found the issue...





Cleaning and re-assemble.














All done but the finishing part.  Waiting for the new drain bolt to arrive.

The thought of slaving away with all that pride of ownership polishing is daunting,to me.Bricks are relatively free from this requirement but hey,if your into that then go for it.I love the utility aspect of my K.I hardly ever clean mine either...my kind of street cred?
As for my (old)Triumph,that is another story.It's definitely not utilitarian and the fettling process catches the next thing to fall off.

Im right there w ya.  The polish took all of 15 minutes.  I just didnt want to deal w headache of anymore shitty chipping paint.  The cover will gain a real nice smooth oxidation over the next year or two and will match the rest of the engine nicely.  Same as the timing cover.

Re: 87 K75C/T "Paint Stripping Question"
« Reply #115 on: November 29, 2016, 06:38:28 AM »
Hey guys after some searches I havent found anything.
Im looking to strip the paint off the plastics.  I tried some lacquer thinner, wouldnt touch it.  I ran out of acetone.  But, plan to try that next.


I prefer not to use "stripper" on plastics.  However if you have a product that works well and you like.


please let me know.
Thanks

What kind of shape is the paint in?  Stripping plastic is a pretty iffy process, especially when trying to remove two part paint.  Any chemical strong enough to soften the paint will probably damage the plastic as well.

On my bikes I just wet sand the old paint with 600 to break the shine and provide a good surface for a white or light gray sanding primer.  If the old paint has any runs or sags I'll hit those spots with 220 followed by 320 before doing the 600.   Chips or dings are filled with Bondo or spot putty after the first coat of primer.

Thanks, this is what I will be doing.  Sanding and filling as you suggested and strip the tank bare.  The tank paint is the worst of it.  The radiator shroud is really the only part badly beaten.

Martin suggested a clutch lever mod that made perfect sense to me.  So, I did my best to duplicate.





Cleaned it up a bit w a half assed quick polish before starting work.





a ball point pen tube fits tightly through the bearings to help keep them clean.  Flushed out shavings before pulling the pen out, then flushed again after.





Done.  Thanks Martin.   :2thumbup:

That's 15 minutes you'll never get back though. Now, you're doing it to the clutch release arm! Onlookers will be blinded! The elderly are distressed about your use of time!
 :hehehe
Your modification is well-done and an example for others. :2thumbup:

Haha.  thanks bro!  P.S. a whole lot of people in this world spent that same 15 minutes watching cats play the piano on youtube.
Im not one to judge.  However I feel my time was better spent.

Better spent than raising your ranking and leveling up in GTA? Anybody can fix up a Brick, but it takes dedication to have a full arsenal, the ability to call in mercenaries and love kitty-watching.
