Hi Ken. Adjusted the PMS screw 1/2 turn. You were right ....it was running too lean. Throttle is nice and smooth, no jumps, and the idle is consistent. Running like a champ. Thanks again for all your help, and for a great product. It's delivered the performance i want with the ease of tuning for a lot less $ than i had planned. Was going to change out pistons, cams, valve springs, ect. ect. You've saved me thousands. Thanks.

Hi Ken, Just wanted to let you know of the great big differance in my bike's performance. It runs better than new. When I started for the first time it fired up and right away I could feel and hear the performance. You make a great product and the K&N fits and looks sharp. Keep up the good work!

I want to thank you for coming down and installing my manifold for me back in March.This past Monday I went for a 250 mile ride with my brother and cousin. They both ride Kawasaki 1500's and they were both surprised at the way my bike ran. My 1100 Star had no problem hanging with them even at 85+
mph. My bike is also averaging about 50 mpg running at 65 mph (with a couple of 1 to 2 mile 85 to 90 mph stretches). It has made a great difference in total performance of the bike. It rides smoother, and has enough torque to climb a tree and riding 2 up is like riding single. Keep up the good work and take care.
