Hey guys,

Doing a rebuild currently on my 2005 450x. It is mostly stock but I just ordered in a Yoshi Slip on that I am going to put on when I put it back together.
I am going to be cleaning my carb out soon and was wondering if it is recommended I change my jetting to anything for a CF TRC slip on. It is all stock jets in it currently. I live in Nova Scotia, Canada so I am not high above sea level.
If anyone has suggestions for what jets I should try changing too would help me out a lot as I dont want to buy a bunch and keep playing the trial and error game.
Thanks
