on my 600 vmax xt 96, I have set up low-altitude (stock, 152.5), needles too and I ride between 1000m (3300ft) and 2000m (6600ft).
So, I'm too rich.
on the data sheet of yam, it says between 147.5 and 146.3 and needles a step up from stock for this altitude.
but now, I mounted twin pipes AAEN and Aaen said to put 2 points higher compared to the stock.
i have to reed spacers , tin gasket , and clutching aaen in primary , secondary stock.
in green , I have
in pink, what should be for stock pipe.

questions is:
is what I can try with the low altitude adjustment without any risk to my engine?
it will not be too lean ?
for me , I think not because I should have 149.5 (147.5 set up high altitude + 2 points) instead of 152.5.
knowing that it is rarely more than -10 in my country and I also ride rarely below 1000m .....
I have to touch the needles?
thank you for your opinions!
