Hey All,
I have a cracked side cover and would like to fix it by glueing it. Anyone have experience in this department?What would be the best glue? One of my tabs broke off.

Thank's
Paul

Broken sidecovers? No, I don't think anybody here have been through this before...

JBWeld and Vegemite 50-50. JBWeld in the sidecover and Vegemite in your butty.... LOL

I used a massive wad of hot glue and super glue to put my tab back in place.

And then the sidecover flew off while I was riding on the interstate.

Don't use a wad of hot glue and super glue!

Hey Raul, what's a "Butty"? You're not putting Vegemite up your arse are you? I wouldn't recommend that at all mate, I've got some in a cracked lip years ago and that stung like hell, so on something as tender as your "Butty"? Oohh the mind boggles! Ha ha, Cheers, Terry.

UK regional dialect (Yorkshire) butty = sandwich

Obviously means the same in Spain...

Geez I hope so Steve, the other option is beyod my comprehension! Cheers, Terry.

To be honest "butty" doesn't exist in spanish though we have adopted the word "sandwich" but only to the ones made with sliced bread, as the ones made with regular bread -subs- are called here "bocadillos".

No, it was just a joke because the subject was discussed earlier, can't remember wether in this forum or the old greenspun. I recall somebody mentioning "marmite in my butty" and we all had a big laugh until they explained what was "butty" in the islands... The thought ot anything approaching my butty, even for healing purposes, make me shudder in anguish...

Aside from the "butty" tales, I used epoxy resin and fiberglass cloth around the broken tab. Don't even try the superglue. I also have reinforced the broken tab with a 1/8" roll pin, by drilling through the tab and into the cover being careful not to break through. Fill the hole with epoxy, and slip in the roll pin.

Yea, sorry - I noticed that after posting.

Now I've really derailed this thread (with my 1000th post!)

Has anyone used the plastic welding services offered by these folks? http://www.cycle-salvage.com

I nearly bought a plastic welder a couple of years ago but couldn't justify the cost. Now that I have two sidecovers in need of repair I hear that welder knocking at my door again. Still, I don't think I'll let it in quite yet.

One of the tabs came completely out of my sidecover once without damage to the pin or cover. I filled the hole with crazy glue and popped the tab back in. been solid for 2 years now. Of course I'm very carefull when taking off sidecovers now.

Raul CB750K1 · « **Reply #14 on:** September 27, 2005, 06:30:13 AM »

Unhelpful? Maybe he didn't get the answer he wanted about sidecovers but now he knows that you better don't mention "butty" outside UK... That can be more embarrasing that riding with a missing sidecover.

I think they are made of PVC, soooooooooo...
try some PVC cement, the kind used for making
plastic sink drains with PVC pipe.

Available at any hardware store, cheap!!

The Classic Motorcycle Mechanic magazine from the UK had an article on the plastic solder. I cannot remember if the iron is special. When I get home I will get the issue #s. Fax or scan. L

Don't bother with PVC glue, that's the first thing I tried (in a small spot first to test the strenght) and the result was very disappointing. Well, you can have a good time if you smell it for some time, but your sidecover won't get any better (chances are you can't care less after smelling the glue...)

I used glass fiber mesh first, and then covered with glas fiber resin -used to fill up holes or dents when doing car repairs. I personally don't feel as if it is much stronger but I feel it's let's prone to crack now.

i used a drimmel tool and cut a small v on the inside of the side cover.filled that in with epoxy the kind you mix the 2 parts,then took a plastic wire tie cut it to the length of the crack laid this on top of the epoxy and epoxy on top of that.all is well now and has a little give to it so not as likely to crack again.

I hope I never have to deal with a cracked side-cover (knock on wood $:-\$ ), but recognized these as a weak point many years ago, particularly at the tabs/posts. I keep the rubber grommets clean and occasionally wipe them with some Silicon sprayed on a cloth. After letting it sit a while, I wipe off any excess. When I remove the covers, I brace my thumbs against the frame and ease them straight out with just enough force to clear the grommet doing the bottom first then the top. I think problems arise when you, or PO

, just grab and pull straight out and put too much torque on the things. So far they have held up for 36 years, first ten of which may have seen some PO abuse. Apologies in advance if this sounds preachy.

Raul CB750K1 · « **Reply #20 on:** September 27, 2005, 04:10:38 PM »

My advice? Reinforce the sidecovers even if they are not broken -much better if that's the case-, with glass fiber mesh and compound. That will reduce the chances for cracking. Then, replace the rubber grommets for new, soft ones. And third, when removing the sidecovers I always use a screwdriver to pry them out. Just use the rod, not the tip, so you can pop out each tab one by one without the risk of one suddenly popping out and you falling on your "butty" with remains of a sidecover on your hands. That way you can have original sidecovers for the rest of your life.

Our Honda sidecovers crack because of the plastic used at the time, due to heat and UV, and there's bugger-all you can do to prevent it. Splotching epoxy resin and fibreglass matt all over the back of them might work,(or might just de-laminate like some I've seen) but it still looks like crap.

I bought a "plastic welder" and was thoroughly disappointed with that, so now I use the "Superglue and Baking Soda" method for repairing them, which works much better than any of the above mentioned "cures". (all of which I have tried with limited success, and mucho mess, particularly with epoxy) The good thing about the superglue and soda method is that it is instant, and mess free. This stuff can be filed, then wet sanded for invisible repairs, and won't damage your paint or ever crack again in that spot.

There are no "tricks" involved, just clean any grease or oil out, "Vee" the crack,(from the back if you're worried about your otherwise nice paint finish) or chamfer around the broken off tab, pour a little baking soda into it and drip some superglue (liquid, not gel) onto the baking soda, and a few seconds later, you're done, time for another vegemite Butty and a can of VB! Cheers, Terry.

A friend put me onto a product 3 years ago that I have used many times now to glue different plastics including fairings and side cover tabs. It is called Mr. Sticky's Underwater Glue. It is amazing stuff. You can reinforce it with cloth but it works pretty good by itself. I have not had it fail me yet. Here is a link -

Thanks for the heads up on the plastic welder Terry. I'll tell the one that's knocking at my door to get lost.

Now for some superglue and baking soda...Of course first I'll have to get that fiberglass resin and tape off. $:-\$

That's it Mick, superglue (Loctite brand is good, but don't use the gel, it won't soak into the baking soda) is cheap, and works on everything. (you can use that method on timber and even metal too)

The problem with plastic welders is that there are so many different types of plastic used in motorcycle parts, that unless you're a scientist, you won't know what you're trying to "weld", and guess what? One type of plastic filler rod isn't compatable with another!

Bugger that mate, use the cheapest method and spend your extra money on beer! Cheers, Terry.
