Have crack/hole in stock airbox

Okay i REALLY want to use the stock airbox but the one that came on my bike has a crack...okay well its more like a hole on the inside seam by the filter. i can put two fingers through it. Do you think i can patch it with some rtv?

i DO NOT want to go the route of getting pods unless i have to. And, i dont want to spend 100 dollars on a used airbox (ive looked on ebay )

 

I have had good luck with jb weld and fiberglass mat with things like that just scuff the area real well with sand paper another option would be some kind of plastic epoxy

 

I paid $10 for my spare (Seca, sorry) airbox. $100 is just plain nuts.

You can try RTV and see if you can get it to stick. Use automotive HD black adhesive RTV and be sure the surface you're applying it to is CLEAN.

I'd recommend using Berryman's B12 carb cleaner; but KEEP IT AWAY from anything plastic that you don't want "attacked."

 

In my experience, RTV doesn't stick to the airbox plastic that well. JB Weld works better.

If you have a big hole to cover, or a crack that needs reinforcement, you can pick up some sheet metal from a hardware store and cut and bend a piece to cover the area, then clean/degrease with brake cleaner, and glue it in place with JB Weld.

 

Never thought of using JBWeld on plastics. Now I've gotta test it. Thx!

 

Has anyone tried ABS pipe cement (not PVC cement) on the airbox plastic?? Available at ACE hardware - the stuff is MAGIC on bodywork.

I also think aluminum tape would hold for a while, maybe need to be re-done annually. (the fix and ride solution)

 

I tried some ABS Plastic Welder I have, from the hobby shop. Didn't touch that black plastic.

It wasn't, however, ABS "pipe" cement. So don't take my experience as gospel. I "caulked" mine with RTV and it's holding.

 

5 Minute platic epoxy and some donor plastic from something similiar. My spare airbox broke during an attempt to remove it from the frame (before pulling the engine) and its now stronger than it was originally.

1. Sand the area to be prepaired with coarse grit.
2. prepare your patch panel to cover the hole. I used an old stereo pocket I cut up
3. mix enough epoxy to cover the patch and lay on a thin layer
4. press patch over the hole, and hold in place for 5 minutes (masking tape works well to hold it while it cures.

Think of it like patching a bicycle tube.

 

I concur... I fixed mine with 5 minute epoxy about 20 years ago when I laid my bike down and it has held fine ever since.

 

i used something similiar from home depot. its the loctite brand plastic epoxy and made some repair pieces from some plastic lying around. i glued them with the epoxy and then screwed them on using sheet metal screws. THIS STUFF IS NOT GOING ANYWHERE!!! i think it dries harder than the plastic lol
