Predator 670 V-Twin Custom Performance Carburetor Carb Stage 1-3 Jet Kit

I was a little skeptical ordering this kit since the description isn't very well done, but it ended up being just what I needed. The predator jets are difficult to source.I was having issues with my Predator 670 running lean after a few modifications. After attempting to drill my original jets and going too large, this kit saved the day!The kit comes with 5 jets to choose from and a few other miscellaneous tools. The directions are very descriptive and I was excellent pleased. I'll order another set to keep on hand for my second predator build.

What you get in the kit is 5 jets and a 3/16 drill bit, absolutely no carburetor gaskets included. Pay close attention to the jets, as they are labeled in the bag, but not stamped. There is also no pretty box as shown, not that it really matter. I installed the two recommended base jets, and unfortunately had to coat one of the 3 carb mounting gaskets with RTV to ensure a seal. Popped the mixture screw caps and dialed in the idle mixture screws, ultimately setting both at 2 3/4 turns out (1/2 more than the stock setting). Any more and the engine would pop through the muffler. The engine would then start hot without engaging the choke. Acceleration through the RPM range was smooth, quick, and very improved. You can possibly drill the stock jets out and achieve the same results. Overall am happy with the results, but disappointed that no carb mounting gaskets are included.

40 bucks for a couple jets and a drill bit ,

WOW! What a huge difference! Engine runs much better! No more lean surging!

Just buy a wire gauge drill bit set and drill out the spare jets that come with your predator 670! This kit DOES NOT come with matches sets of jets. Predator 670 engines run different size main jets when using the OEM muffler. If you replace the muffler you need to have each side of the carb netted the same for the engine to run properly. This kit does not accommodate that!
