          Rated 5 out of 5 by from Honda shadow 750 Jet kit Dynojet claims the stage 2 kit will yield an extra 2 hp. My Shadow can now accelerate on a steep hill where it could just hold 80 KPH ( in 5th gear ) before the kit installation. Although I did not dynotest before and after installation 2 hp seem to be a reasonable estimate of the power increase. The only problem I had was several very stubborn screws that had not been turned since the bike was manufactured 11 years ago. There was absolutely no trouble with the kit. Dynojet's instructions were clear and precise. Installation was easy. Idle, fuel economy, and cold start performance were not affected. I now have more power for climbing hills and passing. Anyone who can take a carburetor apart can install this kit with good results.

          Rated 5 out of 5 by from Works like a charm Put the stage 2 on a 1988 Kawasaki ZX750 with pod filters, easy job, about 5 min each carb. I live at altitude and it still works fine, bike deserves after market exhaust just to get the most out of it.

          Rated 4 out of 5 by from Great performance, but... Results of this kit are 100%! But be careful to use the proper drill bit for your slide vent hole as there are two drill bits in the kit. (It's the smaller one)

          Rated 5 out of 5 by from good instructions Kit is easy to install. Instructions include exactly how to DE restrict the bike. Huge noticeable difference in bottom end power. Just a note their numbering for their main jets are different than how the stock jets are numbered.

          Rated 3 out of 5 by from Ok Kit Was better than stock jetting but have since switched to a JD Jetting kit and the JD is much better so 3 stars for this one. I think CM should consider stocking the JD kits though :)

          Rated 5 out of 5 by from Excellent results The jet kit absolutely changed my bike, woke up from a factory tune, tied up against emissions constraints. Both carbs are now synchronized, and you can hear the improvement. strongly recommend an OE gasket kit while before you start.

          What size jets come in this kit I need 158/55 for my stock keihin carb for xr650l 2013

          Asked by: Mountain man
          The jet sizes included are different depending on your vehicle. If you enter the year, make and model of your vehicle on the product page, the vehicle specific part will be recommended for your bike. You can then view the installation instructions in the item details, and the included jets will be listed for your specific model
