I'm no stranger to the Mikuni hsr 42. I installed one on my 93 FLHS years ago and had about 40 thousand miles on it with no complaints. I like the simplicity of adjusting idle and idle mixture while sitting on the bike. The throttle response is outstanding! I'm an old drag racer and I pay attention to these things. Very satisfied with all aspects.

The mikuni hsr carb kit I've used before and really liked it on my Harley. Fast forward to my 98 road king and the Mikuni hsr is even better. Very good price.

Easy install. Runs better than new.
