Outstanding carb what a boost in power, and the choke works as it was designed. Easy to install 2 things make sure cables are rerouted under the frame and it took some effort to get stock fuel line on the carb fitting. I have taken my 88 inch out to 95 with some Headquarters cams. Performance of carb is great over stock.

Smoothbore Easy Kit Mikuni Carb
I cursed the stock carb on my 97 Sportster until I replaced it with this Mikuni carb.
The kit is complete with the special backing plate and spacers that you need. Detialed instuctions made it a breeze.
This is the best that the bike has ever run. Plenty of strong, smooth throttle. Real quick.

Mikuni hsr42 smoothbore
I have a 2002 Dyna. It has been fouling plugs and running rich since I bought it last year. With failed attempts to tune the factory carb I bought the Mikuni. I love it. It has more power and ran smooth right out of the box. I had to file down 2 engine fins a little for fit, but other than that it ran great right out of the box.
