this is the proto-type Brian,, just to make sure I was on the right track.
the next one will be the one that I put my name on
with out making this post as long as some of the stuff I,ve read and studied, the biggest downfall with the original exhaust is that the header pipes aren,t the same length, the outside ones are shorter because of lean angles, not much but enough,, which is why the balance pipe runs between the 2 near the footpegs, to even out the exhaust pressure between cylinders,
remembering that really we have four motors linked together, same as we need the carbs synced we need all other aspects synced also, so with exhaust pressure, 4 into 1,s do that to an extent,, which is why they work really well at one point of the engine power curve not across the wider range
I,d been annoyed for ages that to fit my towbar on the bike looked silly with the pipe sitting so low, it started the idea of moving the whole thing out of the way and this is what I came up with, the next one will be more compact and hopefully adjustable
oooohhhh,,,,,,, nearly forgot, fair chance it will stainless too,
,, just for Jonesy
