Has anyone used epoxy or JB Weld to repair small hole in heat exchanger?
not sure if that would work buts it worth a try reason being is the expansion and contraction the heat exchanger is exposed too. Do you know someone who welds aluminum that would be a better fix.
I used JB stick on a water pump cover on my dirt bike. Worked great but it was only a temporary fix i did change it out.

I do know someone who welds aluminum. I also have another heat exchanger to put on, but its quite a job to change. Would hate to change it out and have another stud go through as track is getting worn and a new track is not in store for this season. Was thinking of a tempoary fix before changing it out and getting new track.

Does the motor have to be pulled to change out the front heat exchanger? Thanks.

From what it looks like to me, it doesn't. I just hit a rock last week and bent my front exchanger so I was looking at what I have to do to change it. It looks like the chain case (and a few other minor things)and seconday clutch has to come off and then the rivets can be drilled out and the exchanger removed and the new one put in. I checked with hibsman25 on the exchanger and he sells them used for $125. Pretty desent price. For the work involved and the price I would just do it if it's leaking bad. It's alot cheaper that cooking a motor. Mine isn't leaking it's just bent so I will change it in the summer.

I used the 2 part paste in tubes, like tooth paste. I just cleaned it well, sprayed some wire wheel cleaner (acid) that etched it a little, rinsed and dried, applied the J B Weld, next day refilled with water to check for leaks. No leaks and it has been several years now with no problems.

I've used the two part JB weld for many years without no problems. Clean the area well before hand. I use to weld but in most cases that involves removing the suspension what I hate. I use a putty knife and give it ample set time back out riding the next day.

Well just went for my last ride of the season yesterday. JB Weld on the heat exchanger held up perfectly for hundreds of miles and still looks as good as when I first put it on. Going to run it next season like this as well. Great temporary or even permanent fix.
