We got a small hole in one of the radiator flues this past weekend and I was wondering what some of your guys have done to fix one of these? Is JB weld or quik steel, etc good fixes for this? Is there something else you guys have used?

I know some of you with deep pockets say ditch it but it basically just has a hole in it. It didn't get twisted bad at all so I hate to just throw away an otherwise good stock radiator.

I will eventually use it as a spare but for now i'm just looking for some repair suggestions.

Caswellplating.com order a can of lab metal and reducer. Its liquid aluminum. Worth every penny. Strong as a weld, not brittle like jb weld. It literally is aluminum in liquid form.

I used JB weld on mine two weekends ago but it wasn't to patch a hole only on the outside structure and it worked awesome, if you've never used it that stuff is super easy to work with and is good up to 500 degrees and rads shouldn't get near that. I rode two weekends so far and it still has held up great but can't vouch for longevity. Harbor freight sells or used to sell sort of a brazing rod that melts to aluminum and is specifically designed for aluminum. I've seen successful vids on the internet but when I tried it myself I couldn't get the radiators hot enough for it to melt so I cannot recommend it but might be worth looking into. Maybe if I had an extra set of hands with another torch heating it that could have been the ticket? 3M and other Co's make aluminum epoxy but they are expensive from what I hear. Honestly I'm the king of making shit work but I'd get a used one on ebay, maybe use the JB weld just so you can ride until it comes in. I looked last week and for my bike used rads were like 35 bucks for the pair.

I have used JB on YZ85 radiators where the bottom mount is. Worked better than replacing as they new ones would crack there the first time you laid it over. I had three bikes running this patch for years with no failures. The other stuff posted looks better but easier to fund JB in a hurry..............

5 minute epoxy. It's clear and works great. My 125 had a pin hole in one of the cores. I 'moved' the fins out of the way, scratched up the core with some sandpaper and filled the gap between the leaky core and the closest one for about 1/2". It's been working like a charm for 2 years now.

Any hardware store or auto parts store.

Send them to radiators to Brett at ICW. He does awsome work.
Seam welds them and pressure tests for a good price!

We got a small hole in one of the radiator flues this past weekend and I was wondering what some of your guys have done to fix one of these? Is JB weld or quik steel, etc good fixes for this? Is there something else you guys have used?

I know some of you with deep pockets say ditch it but it basically just has a hole in it. It didn't get twisted bad at all so I hate to just throw away an otherwise good stock radiator.

I will eventually use it as a spare but for now i'm just looking for some repair suggestions.
Damn Robert, those look great. I might have to send mine over to him.

Pretty cool of you. I wish there was more people like you on this board.
