I have kicked around the idea of rebuiding the motor but then though about just buying another motor. so I started looking. found a 125 with a replacement motor that was installed in 2009. I went to check it out and it runs good but has a leak where the drive shaft goes in the rearend. motor is good. so my intention is to take the replacement k301 out and put it in the 129. I just wanted to make sure im making the right decision. thanks

I think you have already made up your mind to do just that. If you have no need for both, throw the old engine in the 125 and sell it to offset the costs of buying it to repower the 129. I have a parts 125 that I have been selling off piece by piece and a 149 I am re doing. The 125 is a PITA to get some parts off of it, just the nature of the beast, the 149 is much more user friendly.
