Someone talked of making a replacement out of stainless steel.  Run a search and see if you can find it.  There were a lot of responses, although he hasn't made any yet.  A few years ago someone else made a few.  I understand the problem, I have it on the Interstate too.

+1 on painting it. Peel off the rest of the chrome give it s light scuff and paint it. Rustoleum, and krylon stick good. Duplicolor not so much...

1. Peel, fill as required, wet sand...

2. Primer, Color, Clear Coat & wet sand, polish, wax...

It'll be mistaken for OEM.

Somewhat costly unless you have some laying around as I did.

Thanks for the pics.d  And I'd guess it's no more costly than multiple replacements of the cover.  I'm on my third one now.  Sad   At a 1/4 inch thickness, I'm curious of it contacts the alternator, and if so, does it cause any heat buildup in it.  ???

Sorry.....Good point I've got to be more careful when posting info....actually the stuff I had laying around was for protecting wires, it was about 1-1/2 in diameter and relatively thin, ~ 1/16. Cut it open at the stitching and sized it to fit.  Used a heat resistant gasket sealant for adhering to the cover.  There is contact on the top so you're not going to want to go thicker, front is good.  Warm to the touch but not hot.

Stripped it & painted it with semi-gloss black engine paint.
Looks good on a Valk with black in the paint scheme. Not so sure if I would like it on any other paint scheme.
I do love that body color cover!  cooldude

Ok...I see the fix idea's, all good. (good to see you here Dennis)
  I'm looking for the cause and I think I guessed wrong by looking at your fixes. It appears to be heat related?  I spilled some fluid on mine while bleeding the clutch several years ago and then some time after, I noticed the chrome bubbling up. I thought it was from the fluid contact? It also damaged the paint on my frame below it, so I thought it was caused by me and not the heat issue.
  Any ideas, have any of you done the same as me?

ValFlyer, Nice job on your bike cooldude Love your paint.

Some may be heat related, but I think a large number if not the majority of bubbled covers can be traced to fluid, usually gasoline that's been spilled on them.

I have one with over 160,000 with no issues.  I had one with 86,000 miles I had to replace.

Yep.....several guys have told me it's most likely from GAS dripping down on it from tank removals.... cooldude

I'm not doubting your word for one minute, but that's amazing.  I can't remember if I've ever seen a good original one.

Mine on my 97 Tourer is original and its pristine.  I always cover it with a rag when I take the tank off, so no gas has ever touched it.

hey there Tundra, yep been gone for a while...and thanks...

Here's my take on the alt cover crinkle. HEAT...

Bought my Tourer  new in Dec. of '97.
It started crinkling at the letter box corners a few years later and just worsened over time.
To my knowledge, not a drop of gasoline or other chemical has come in contact with the alt. cover.

What I did witness was some pretty serious warping of the cover a few months after I painted it. Damn It-all that work wasted.
The direct cause was HEAT. It warped while I was synchronizing the carbs. I sync'd via a 6-line ATF homemade setup that took awhile because of it's accuracy and that a slight adjustment for a final fine tune to a single carb would throw 3 or more carbs off.
I finally gave up on perfection before I noticed what an hour of runtime heat had done to my alt. cover. Box Fan Didn't help cool the the rear case or alternator.
Although the paint held up the ABS warped quite a bit.

Gasoline may contribute to the OEM Chrome crinkle effect, but I definitively saw what heat does to the cover.

Add to which you can see in the pic of the peeled cover that it's slightly warped on the left face. That's why I had to fill prior to painting to conceal the warped ABS. I doubt gasoline is going to warp ABS, maybe if it's submerged in a can of gas for a few days it would.
Sorry, I don't feel even repeated spills will crinkle the chrome.

I'm convinced it's heat...
And will remove my alt. cover from now on to prevent damage while running the engine for any service beyond 10-15 minutes.

Nothing to do if your caught in 90* slow moving road construction. It's gonna get hot and crinkle.

I believe you may be on to something.  Mine has never sat still with the engine running for more than a few minutes.

I ride in all kinds of temperatures.  I consider ninety degrees to be ideal.

Of course we're both making general judgements based on our own experiences, by definition samples too small to be meaningful.   Wink

I think its a combination of things rather than any one thing.  Mine sees more heat in my garage than most people's do riding.  During the summer, the temp in my garage seldom goes below 100ยบ.  There are advantages though - I don't have to start it to warm the oil up prior to oil changes.

That cover comes off with one bolt, If heat is suspected culprit, I'd remove the cover before syncing carbs or removing the tank if gasolene is the curprit.  I suspect either or both could cause it.

I feel better now, mine started the chrome crinkle a few years back and I was thinking that I just got lucky and got the one made on Monday morning from the guy with the major hangover.... uglystupid2 now I see that it is a far more common problem.
