KIPA Carburetor For Mikuni HSR42 HSR 42mm Fit Harley Evo Evolution Twin Cam Glide Dyna Super Wide Lower Rider Disc Glide Fatboy Heritage Softail Night Train Road King

Pros;- quick install, had it installed and running in 5 min- good option when on a budgetCons;- Sealing gaskets are junk, the float bowl and drain plug o-ring didn’t last after just 3 removals.- Stock pilot jet isn’t labeled. The two extra pilot jets included are labeled 42 and 45. Assume they are 22 and 25. Not a huge deal just swap out and see how the bike runs.

I'm replacing a HSR45 which is just a little too big for my application and this HSR42 clone was the ticket.Very nicely built and works great.I had to increase the main jet to a 185 from the oem 160.I installed this on a Road Star 1700 that has a two into one exhaust and a high flow air cleaner.Note; The slide tends to stick a little under high vacuum but after 20 miles I no longer noticed it so I'm assuming that it needed a little breaking in.Side by side this 42 looks just like my genuine Mikuni 45 except it's polished...Very nice clone!

I have a 2003 sportster 1200 and have been going through a tough time getting it to run right after sitting from the previous owner. It would idle but would not run correctly under load. Tons of research and replacing ignition module,coil,p!ugs,wires,rebuilt carburetor 3 x , went to gravity fed petcock, still no luck. I finally just gave this a shot after reading the positive reviews and saving about 160.00. Bolted it on and end of problem. I have a real mikuni on my softail and honestly can't see a difference in carbs.Actually this one is more polished . hope this helps someone having the issues I dealt with. Bike is running great.Quality from China is definitely going up.

Have been dealing with a carb cough with my CV40 on my 06' Sportster 883 (stage 1) for months now. Troubleshooting with no success from jetting and intake seals to coils and ignition modules. Had read over and over that upgrading to Mikuni 42 or S&S carbs solved the issue and finally pulled the trigger. I bought the Kipa HSR at 1/3 the price of a genuine Mikuni and am so happy I went with the Kipa! Great product, great finish, and best of all... unbelievable performance and absolutely ZERO carb coughs! Throttle response is night and day from the CV, and haven't had it cough once. Would highly recommend buying a name brand Mikuni rebuild kit for the carb before installing to ensure all seals and o-rings are in good condition correct size, as well as correctly sized and labeled pilot and main jets. I left the needle jet and accelerator pump as-is and they work just fine for me with my application. Will be buying again and again for any V-twin application I have down the road. Wonderful product!

Installed just fine as soon as I turned it on though it starts leaking like a sieve from the overflow I bought this cause I didn't want to rebuild carbs but apparently I have to poull the float bowl cause it won't shut not not happy with it
