after smearing hi temp copper "band-aids" ON the joint 2 or 3 times,
only to have it burn thru after a few rides,
i finally pulled it completely apart, layed a heavy dose of the hi temp copper about 2" wide and an inch or so inside where the over piece ends, then reassembled it and cleaned off the excess mess i had created.
it lasted a whole season before springing another small leak.
at that time i had had enuf and sold it before i did break out the welder.
fyi...out of the 4 right bend pipes i have tried, that LRD was a close second to my favorite trinity
