2008 (250f) KX500AF
« on: May 12, 2019, 08:20:06 AM »
New to forum but lurked for awhile.  With that said I Just got done building a 2008 250f af conversion and man is this thing totally impractical for the street but holy s**t is it fun as hell!

Used a 2009 acerbis tank for 3.3 gallons capacity and a 2003 kx250 seat. Doing so raised the seat but I'm a big guy and that's what I wanted.

Using a Pantera starter but as of now the cranking RPM seems to be  right on the edge to produce spark with a 250cca battery. I installed a decompressor which helps (310rpm) but is really odd that it does as cranking RPM is slower with less compression.

Running a 15 44 gear and can "cruise" at 5900rpm at 65.

Have 230 mIle clocked and run 93 octane at 40:1 using Amsoil Dominator.

Hi DHouge, welcome to the site. Your bike turned out really nice!  Did you buy the rails or bend them yourself?
Perhaps I have a dirt bike addiction?

Thank You Umberto

I Bent the rails myself.  Summit racing sells the die's and I was lucky enough to have a buddy with a bender.

To make sure the tube bent well I capped one end, filled with sand compacting along the way and then capped the other end before bending.

Had access to a manual mill for the motor mounts as well.
