Hello guys! I've got about 9k miles on my Strada so far and recently I've encountered some problems while twisting the throttle at around 3-4k rpms in multiple gears. While I accelerate, the bike seems to exhibit some jerky movements, the throttle seems to disengage/engage a couple times which rocks me back and forth slightly and then past 4k rpms it goes back to normal. Could it have something to do with the spark plug? Maybe the valves since I have not checked them yet? UPDATE I just realized there is a thread about a similar issue at http://www.cafehusky.com/threads/dead-spot-about-3000-rpm-under-light-load.35833/
