You have to have a real feel for using feeler gauges, but at least you didn't need an assortment[/i] of shims. The best set up was the hydraulic valves on the Nighthawk 750 which never needed adjusting. I wish this bike had those.
You can say that again! I put away my feeler gauge back in the 90s, when I no longer had to measure valve clearances or point gaps.
I wonder why Honda chose not to use hydraulic tappets on this bike? Generally, you don't use them on high revving engines because the rpms will ovewhelm the rebound capabilities of the lifter (called float). The CB1100 has a nice low redline, just like the last series of Nighthawks. I just can't figure why they wouldn't incorporate such a great feature when designing an engine from scratch.
I'm really disappointed because I truly hate adjusting shim and bucket valves. On the bright side, they usually don't need actual adjustment that often.
