Mikuni HSR Smoothbore Easy Carburetor Kit

Great carburetor, easy install as stated. Definitely better performance out off the box.

Easy install, able to use stock air cleaner, o.e. choke cable w/mikuni supplied spring and barrel.

Easy install and a phenomenal performance upgrade. Crisp throttle with instantaneous response. Don't even consider other carbs, this us the one to get.

Great performance out of the box. Did a little research and fumbled upon Joe Mintons settings. Followed them to the letter! The old girl runs like a champ. Instant throttle response. More power than ever. The bike just seems happy. Definitely 5 stars.

Works great. My Fatboy runs better than ever.

The carb did what I thought it would and should.

After using this unit for some time, I'm able to say it has worked perfectly, fit as expected, was tuned out of the box, and simple to install.

I had 3 minor issues, but I'm very pleased with the HSR42. 1) Instructions said V.O.E.S. Switch must be relocated behind horn for carb to fit. This wasn't mentioned in ad. I found an easier way by removing the mounting bracket from the VOES switch, connecting it to the carb with a 1 1/2" piece of hose. It just floats above the carb vacuum fitting. I didn't have to disturb any wiring. 2) Ad said Sportster choke cable would work. It does, but it's too long. About 4" shorter would be ideal. On the CV carb the cable comes out of the carb toward the rear of the bike. The HSR connects on the side toward the front, putting it closer to the knob mounting point. 3) Sportsters use 1/4" ID fuel line. The HSR carb sent me has a 5/16" ID fuel inlet. This caused a trip to the hardware store to get a 5/16 to 1/4 barbed reducer. No problem, except now I have 4 connections in my fuel line instead of 2. The good part is that once hooked up the bike fired right up, and ran better than ever. The HSR was tuned good enough for me right out of the box.

Highly recommended, did zero tuning on this carb and slapped it on my bike right out of the box and it's running amazing.

This is a terrific carb for your old H-D. With the tuning kit, you can dial the carb in to meet your specific needs, whether that's higher MPG for touring, or higher HP. Really great carb. Lifesaver!

Love it. Night and day difference. Install not too bad I have to say.

Put the HSR 42, 42-11 Easy Kit onto my 2000 Buell M2. Easy installation, quality product. Jetting out of the box was near spot-on. Crisp throttle response and a lot of fun to ride. Feels like more power. Good product. These are the guys to buy from!

Sick of messing around with my cruddy old carb. This thing with a little tuning really opened my hog up! Only complaint is the long idle cable, other than that highly recommend!

Great product, fit perfect.
