the two tees plan doesnt work because the crossover pipe is much longer (50 mm)
there is also a kz650/1000 for vm26 tee that looks the same in the picture, and has the right lenght, 39mm
I have a set of vm26 here and it looks the same, but the inlet is much smaller.
planning on writing the seller a mail.
maybe he has the rights ones, or maybe, if more are interested he can make the correct ones, he does so (or has them done)
for a few other models, all of them bored out a bit larger than stock. all about $17 for the tees and $12 for the pipes.
I have picked up a rusty spare set of sixer carbs for rebuilding later, maybe I can send the tee and pipe and he
can make spare ones for us all..
