I recently purchased a 1997 FLHT Electra Glide that had a stage 1 upgrade (air cleaner and pipes) and noticed it ran rough when cold, coughed and spit occasionally when warm, and in general just seemed to run lean. Playing with the mixture screw did little good. So I did a lot of research and determined that the jetting was probably off. After learning about CV Performance and watching the videos, I became convinced this was the problem, and that I even might be able to do the repair myself, even though I had never taken a carburetor apart in my life. I ordered the kit and it showed up 3 days later. Removing the carburetor from my Electra Glide took about 2 hours total, as I was very careful and also cleaned things up as I went through it. I didn't have to remove the gas tank but I unbolted it and propped it up slightly so I could more easily work the carburetor out. When I finally had every cable, line and tube removed the carburetor slipped out. Next was removing the carburetor top and float bowl, which proved to be challenge as 2 of the 4 float bowl screws were impossible to loosen without stripping the head. On those I had to use a vice grip and force them off. Luckily the CV Performance kit comes with replacement allen head screws.
Installing the new jets, needle and spring was very easy, probably the easiest part of the whole job. I put everything back together and began to reinstall the carburetor on the bike. It went a little easier than removing it as I had a better idea of what went where, and the whole process probably took another 90 minutes. The throttle cables are a little difficult to get back into their slots but you just need to work them a bit. With everything bolted back together I was nervous about starting it up for the first time, but nothing to be worried about as after a few cranks the bike started right up. I immediately noticed it ran much better when cold, and I could ride away almost immediately with no coughing or spitting at all. I left the choke on for only a few miles and then pushed it in, and once again I noticed no coughing, whereas before there would have been. After a few miles to warm it up I could definitely tell the difference. No leanness that I could determine, and basically perfect carburetion no matter what the RPM.
This kit solved the problem entirely. What a great product from CV Performance, not to mention a sense of accomplishment because I did it myself.

I have been busting my chops on this carb for years. I met a guy at the Phoenix NASCAR race at the Harley pavilion. He told me about CV Performance and I ordered the kit as soon as I got home. All the stumbles are gone. My bike has never run better. No more stumbles at 70 where I like to cruze.

Installed the kit bike runs great, got rid of the backfiring. With the instructions and the videos very easy to install. Could'nt be happier, some of the best money spent so far. Thanks for a great, affordable, American made product!

Had carb sent out for rebuild cost a good sum of money and it still didn't work. Well, Thanks to CV Performance to save the day plus my nerves. Purchased the deluxe tuners kit plus other parts I needed. Clean, install the parts easily, back in business again. Thanks CV Performance.
