brute force dynojet kit is out

[neckbone]

has anyone took a look at this kit it recommends 152 front jet 155 rear jet
changes both needles and springs if you run an aftermarket pipe can this be right hmf recommends much larger jets could the smaller jets be because of the needle and spring change

[motoz/HMF]

Dynojet's jet index sizes are not the same as Mikuni or Keihin jets, so don't let the difference in numbers throw you.
DEPENDING on the needle taper you MAY also need to change the pilot jets...the fuel screw will determine that.. IF you are out 3 to 3 1/2 turns out from lightly bottomed you WILL need to change the pilot jets.

If i get an HMF will i have to rejet for summer and winter riding. winter riding is sub 0 celsius and summer is in the 80's F.

With that much of a change you might have to adjust the jetting.
