B50MX Spark Arrestor 1973

Hi
.
Prompted by Dave's post - Triumph TR5T Exhaust Spark Arrestor I thought I would provide a bit of detail concerning the J&R Krizman spark arrestor supplied with the 1973 B50MX.............
.
I've always thought the B50MX 73 twin exhausts looked unfinished without the unobtainable spark arrestors, so I made up a pair of fake tails to complete the assembly:

I brazed some 1/8" (3mm) wire in a cross in the opening of the pipe to stop anything falling down the silencer and left the ends proud so that they would form a stop against the silencer. Finished them with black heat resistant spray paint.

Incidentally if anyone requires an original spark arrestor Peter Quick at 'bsa unit singles' has one for sale at the moment
