Anyone out there with any experience with any of the jet kits out there? I cant decide if its worth the $ for the slight increase you may experience. Considering placing one in my 300 4x4. Any experience and help/suggestions would be greatly appreciated.

 

I put K&N's filter/Dyno jet kit into my 400EX, it made a worth while difference.

 

what did you have in mind.......whats in them?

 

Not what's in them, but, is the performance gain if any you experience actually worth the investment?

 

Yes they are worth the money, and they aren't that hard to put on. I put mine on myself. I know quite a bit about my carb now that i have tinkerd with it some. It really helps your knowledge of the bike to tear it down, and tune it yourself. Its a good feeling, and the performance you gain is decent.
