Anyone else do this? I pulled the diaphrams (sp?) and removed the needles.. Then went and got plastic washers to place under the needles, to move them up and create a richer mixture an mid/high throttle openings. I have been tuning my carbs for the Vmax's new home, at our lake house (elevation 5,500') so the mixture was a bit off VS sea level in Los Angeles where I used to ride it all the time.
Basically, with 1 washer under the needles, it had the best all around power, good low/mid and a very steady hard pull up to redline.
With no washers, the low/mid range was a bit weaker, but up top when vboost hit, the high end rush was the best. Pulls like a freight train!
With 2 washers, it made an awesome sound, burbling and grumbling on deceleration, but was clearly running rich. Down low it made great power and had good response, but started to break up past 6,000rpm.
For sure a fun little project to fiddle with, and see what your bike likes best for your air/elevation. In the end It's running a bit better so I'm happy.
