125-200cc Rim Repair/Replacement Help

Returned from a ride at the weekend and while unloading the bikes a friend noticed a crack in my rear rim (2004 CR125 with OEM Excel rims).

I have heard of people welding them but I'm a bit cautious to be honest, although I do have access to good Alu welder guy....... Anyone else here ever repaired one?

Gut feeling is that I should change the rim, is it something I can do myself if I make a simple jig for the building/truing ? and an pointers appreciated!

Thanks

Weld it. That's usually where it was welded from factory. I do it all time on vintage bikes. On the inside of rim your welder can do an extra wide bead, then grind it smooth but leave little more weld where you don't see it.

I use Buchanan, and yes you can do this yourself. Other than a spoke wrench your bike is your truing stand, two zip ties and some tape to hold them to the swing arm.
Oh and beer after not before LOL.

Been a while since this post but did ended up getting it welded up. Has had a few outings and the bike is now in bits for new linkage bearings, 165 kit and various other bits & pieces.
suffered a puncture on the last outing and just noticed the rim has cracked again, worse this time so going to replace it.

A couple of questions:

I was under the impression that 125 2t's used a 1.85 rear rim but the husky has a 2.15? Is this the norm?
I have a 1.85 spare rim could I use it for the replacement or should I source a 2.15 rim

Thanks

Sorry to hear it didn't hold up but thanks for validating my decision to pull the trigger on new rims. My front had cracked just like your rear. I also had a ton of corrosion.

This being the second time round I just don't think I would be happy ridding on it, first time it had just cracked on the side this time it spread along the inside towards the spokes.

Any way I have a spare rim but its a 1.85 where as the original is a 2.15 , is there any reason at all why I cant/shouldn't use the 1.85?

Also can anyone suggest spoke supplier in the UK and is there anything specific with the 2004 hub that I should be aware of when ordering spokes or matching to a rim?

Thanks
