    When upgrading from a 125 to a 144 one would have to re-jet right?

    The dealer is putting the 144 kit in for me... Just want to make sure they are doing it right?

    I should expect the get the piston and rings and jet from the 125 when picking up my 144 from the dealer right. I would think I would be able to keep the 125 parts in case I want to switch back...

    Can anyone provide me with a list of parts I should make sure I'm getting back from the dealer?

    Make sure you get:

    - 125 cylinder
    - 125 head
    - 125 piston
    - 125 ring
    - 125 power valves

    Keep em all, you can always send the cylinder, head and power valves off to Walt for a 165 kit :-)

    No the WR 125 is a great bike and some love the top end that a 125 gives you. For hills etc more torque is of benefit though . . Especially if you dont want to ride at 9 or 10 tenths . There used to be a factory 144 kit - I am not sure whether that is still available but it can still be improved ( power valve and port timing) the 165 very good value and is finely tuned to perfection - am I right guys?

    The 165 is a nice option to have available. It makes far more bottom/mid than either the 125 or 144 and still rips well on top. It really depends on what you want and how you ride. The 125 runs very well and for many it and the 144(very similar powerband with just more) is all they want. I think for most riders that get a chance to ride all three back to back they will gravitate to the 165 but certainly not all. They are all a blast to ride so enjoy.

    It depends what you are looking for in a ride

    the 165 is for sure torquier and a bit more forgiving giving the situation you put it in

    where you need to down shift with a 125 (a sandy bog or just a small steeper stretch of the trail) the 165 is just open up the throttle a bit more.

    I can not say you are able to drive faster then on a 125 but for sure its a tat easier to drive as fast you can.

    and that makes again the point for a 125 driving fast in a 125 trim is an achievement that you can be proud of as it requires much more skill than just throwing more power to it

    but then again power is addictive;)

    both ways will give you a grin on your face an that's what matters Up to you what you take
