2004 kx 250 2stroke AF conversion with 06 kx 450f

Gonna have to cut and re weld the frame for the header pipe to fit and also cut off this bracket that isn't needed

Let me know if you guys will be interested in seeing me post everything as I go and also the frame is a 06 kx 450f frame.

Picked the 450f up for 200$ it needed and entire top end and muffler/header pipe

Yes post away, the build section is my fav.

I was wondering why the 450 frame until I saw your post on picking it up cheap.

Yeah it was just really cheap and I got the bracket that was in the way cut off it just needs cleaned up better with a dremel on to the next step

Frame just needs modified so cut and re welded to bring the exhaust port down lower

Mounting brackets need cut off and re welded in the right place

Cutting 1 more piece out for the other side and having it welded together tomarow hope it all goes as planned

I’m looking forward to seeing this one John, post away

I dropped the frame off at a fabrication shop to be welded up yesterday he said it will probably be this next Friday when he will get to start on it . the welds are going to done kinda like square tube telescoping which is putting smaller square tubing inside of the tubes on it to have perfect alignment and so the welds are strong but that's all I have for right now I will post pictures of the frame once I pick it up it a few days.

Should I use the 250 plastics or the 450?

All welded back together now to re weld the new engine brackets

I think I'd be asking for my money back and taking it somewhere else to have those welds redone if it was my bike.

I'm going to get those welds brazed over and hopefully it will look good I'll post pics of that once I get it done.
