Has anyone tried the STIC metering block? I just came across the product--never heard of it before. From what I gather it is supposed to improve the atomization of fuel in Keihin carbs. The site has dyno results that show the improved performance over stock carbs. It's a little pricey but it looks like a well-made part. Here is their website:
This STIC metering block for keihin carbs is a shocker in both our dyno and field testing. Great gains in power, throttle response, acceleration, and overall performance. ALL ktm 125 - 300 models...
