Dyno jet kit and jetting

[Hall400ex]

I recently purchased a dyno jet kit and when i was installing the dyno jet adapter it broke. I already had a 175 main jet in so i just installed the new 190 needle in the dyno jet kit and left the 175 in. i have lrd full exhaust system, k&n with my air box lid off, it seems to run fine no dead spots but the dyno jet kit only came with a 170 main jet so is there a differance in a honda jet size and a dyno jet?? THANK YOU

The jet kit needle is designed to work with the jet kit jets so getting an accurate comparison from that list of numbers and others is going to be difficult.

Not saying it wont work but you may have to find out on your own rather than trying what someone else is using.
