I have the chance to buy a 98 kx125 w/out engine really cheap, I've got a riding buddy with 2 bikes but I want my own. If I wait to buy a complete bike it will be 6mos or more. I can do the work myself except for jetting =) I was thinking of getting the parts and locating an engine from a 125 or 250 and slapping it together. I have found motors for fairly cheep on ebay etc. Has anyone done this? Did it work or was the project scrapped?

I used to have 7+ streetbikes at one time and was able to do 90% of the work myself and I know more now so the ability is there. Just not sure what pitfalls I may run in to. Don't want it to end up costing $3000 for a 125.

If you have the ability and tools then it's not that bad of a job. A guy I work with is always telling me about his brother in law that buys all kinds of parts of Ebay and builds bikes that he then sells.

That's something I wanted to do with streetbikes years ago but I just kept getting attached to them. Any tips on where to look for parts online besides ebay? Local guy wants 900 for a motor. Found a few on ebay.
