Swapping my 380 motor into a modern frame

[eprovenzano]

I'm thinking (dreaming) about a winter project.  I'd like to swap my 380 motor into a more modern KTM frame.  Best case would be to find a KTM 250/300 smoker and swap the 380 into it.  Worst case (more effort) would be to swap the 380 into a 250 /350 /450 KTM frame.  Finding a blown stroker is much easier then finding a smoker.  I've been doing a lot of research, and am looking at making the swap.  I'm looking for a roller in the 2012 area.

Also keep in mind, I'm a cheap ass....  So I need to find an inexpensive broken bike that I can either toss the motor, or better yet sell it... 

Nothing started other then a lot of reading and a lot of dreaming...

Hey Eric

So just how bad is the stock 380 frame and running gear? I have thought about doing this sort of thing myself but wonder if its really going to change how much fun I have on mine. Sure, maybe I can go a tad faster and the forks will not hammer my wrists as much on the stutter bumps but overall the bikes works ok right now (except for the motor which of course is a taylor made grin generator).

That said, if you do start into the project please document the steps in detail for me!

The frame swap will drop the bikes weight plus the suspenders will be up to date...  If, and when I do make the switch, I will document as I'll need to so I can remember what the hell I did...  I'm still looking for a suitable roller, so no news yet...

I don't see too many KTM rollers for sale but maybe you will get lucky. You may have to buy a running bike and sell the engine to recoup a little of your cost. Sounds like a fun project but maybe not one for a cheapo  .

I found an 06 KTM 250F for $500... decided to pass...  if I'm going to go through the trouble and expense, I prefer something a little more current.
