Duncan or Yoshimura

[quad97]

I am debating on whether to get a KTM or Suzuki for next year and if I get a suzuki which is a better motor kit the Duncan national 450 or the full yoshimura kit. if anyone has compared these two before i would appreciate an oppinion.

I always recommend duncan, but for the suzuki yoshi got excusive rights to work on that engine and develop engine kits for it. Basically what I mean is they have more experience with that motor compared to any other company or builder. So I would lean towards them though I do swear by duncan and their work. Either way you can't go wrong.

Duncan has been awesome to me no matter what I say about them.
