any pics of where the hole enters the combustion chambers ??
i know you a bit concerned about people saying it would block on the outer edge just think the hole in the outer edge is a safer option [ could also make it harder to do any head work at a later date [recutting squich band]
saying that ...

IS there a reason to do it on the right side? I don't see why anyone would want to put it near the pipe. The left side has no obstructions, especially ones that could burn your hand.

Nice work regardless!!
best position on gen1 af , can visually see it setting on bike , simple to press

probably not worth much more, looks like its been sitting outside for ages judging by the state of the faded panels ,looks like there could be a few parts missing chain, peg,and the rad look a bit bent,
make sure u got plenty of time on your hands if doing conversion
sometimes it work out cheaper ...

got mine fitted 125usd inc decomp valve and head skimmed , brillant job, highly recommend the guy that did it, cost me 55usd to send three heads from US to uk[,done2xKX 1Xcr ] you are going to have to drill the hole in the right place which can be tricky, the X you have marked is going through the ...
