How Can I Fix This, Broken Seat Cowl Tabs.

See picts. PO had repaired this by super gluing plastic washers onto tabs. Did not last long. Just looking for a solid repair that I don't have to worry about it flying off!

Perhaps bonding a plastic washer onto them? I would try that first. If that does not work out, I might try to cut the tab down a bit and use an offset piece of sheet metal with a hole drilled through one end. Maybe multiple coats of liquid abs could permanently bond the metal to the tab base? ( or, you may want to use a strong glue first, then apply the liquid abs ) I read somewhere that abs shavings can be dissolved into a slurry using acetone as the solvent. Supposedly, multiple coats can be painted on and when the acetone evaporates, only the abs plastic remains. I have not used this technique myself, but it may work??? Good luck.

Plastic welding, JB weld, epoxy?

Pretty sure there's a how to or 3 on here. :beer:

sandwich, the plastic, with 2 strips of metal cut down to size drill mounting hole and glue/ziptie/bolt to plastic tab

Just make a thin alloy replacement tab, make it a couple of inches longer so there is something up the inside of the cowl. Cut off the remains of the plastic one & either bond the alloy to the inside, can be done with plastic weld through holes in the alloy, or artaldite etc. Or drill & rivet in place.

Member Resin did a few topics on this, so look him up in the directory and you will get to his topics.  (cannot cut and paste for some reason this morning)

As previously mentioned, you can use a dissolvent to make your own plastic.. I use MEK.. Not the nicest stuff to work with... MEK or Methyl Ethyl Katone differs from Methyl isobutyl ketone (acetone). MEK dissolves rather slowly but what I find is that the ABS doesn't become britle after it hardens.. The fixed structure becomes as on as it used to be..

Here on the rear end of my 1000R you see a white plastic filled in line to repair the structure.. I cut an old sidepanel (make sure you strip the paint of) into tiny pieces like a granulate size and disolved the granulate in MEK making it a goo.. Used that as afiller to repair the structure.. After two days of smearing and hardening, I sanded it down.. It was a great result for me.. (Beware MEK is a known carcinogenic.. (Wear proper PPE and use it in a well ventilated area)  It is not widely available. But a specialized (house) paintshop should have it in stock)

Thanks Dutchy Just the thing I was looking for and Thanks to Resin for the post> now I have to collect the materials and get busy!

Western Powersports in Scottsdale, AZ lists some NOS parts including that seat cowl. They're listed as below cost. Some have been sold - however they do not update the list. Maybe give 'em a call and see if they still have it. Don't get hopes up for the 8 spoke, it's been sold.

I had this same issue with my seal cowl. I used Plastex and it worked out great.  I'll see if I can post a picture of this fix.

I've used this stuff a bit and had good success with it.

I used plastex and got a perfect repair. I'll post pics tonight.

It's the rear tabs that's the absolute c*nt to repair.
In fact, anyone come up with a solid way to create/repair tabs on the REAR of the cowl for a 90-93? It's an absolute dog, I just can't get it right.

Go to an auto parts store and purchase a plastic bumper repair kit ,about $10 and read and follow the repair procedure . I use these all the time to fix and repair bumpers ,dashes and all kinds of plastic ,they work great and are relatively easy to use . If you need to fill an area make an area using tape or tinfoil to shape it add some of the reinforcement tape and fill ,then sand and shape as needed .

I've made those seat cowl tab repairs several times.

Don't suppose you have any photos etc?

On my rear tabs,  I make them over size then trim to fit.
