Any one know if you can get a epoxy or resin that can seal a small leak on a cr250 radiator?

Would araldite work?

if it was me, id whip the radiator off and just take it to an engineer and get him to blob a bit of weld on it. far better than resins or glues i reckon.

I have used some stuff called Devcon aluminum putty, and several similar products more recently. They are a two pot epoxy, a bit like araldite with aluminum filings in it. Really good. Machinable when cured and everything. Try Paykels or similar. But the knead it stuff is pretty good as well, and more widely available. I think both are OK with the temperature.

Good luck.

if you can find a welder who can weld alloy the thickness of a cigerrette paper- good luck!

This is what I was about to recommend - wicked stuff!- Locktite do a version too, The radiator guys use something that looks very like the loctite one- a soft grey liquid that sticks like shit to a 2 year olds undies.
