Another 450F to KX500 conversion

[ToomanyKaws]

My frame was dropped off today with Jerrys frame rails, a mock up motor and a bunch of color pics from this site.   I think we have most of it under control.   Few questions though.

Where have most mounted the coil and ignition box?

As far as Radiator mods.   Most move the left, (shifter side) lower radiator mount on the 450 frame up?  And then mod the radiator mounting tab?

Any help will be appreciated.   I have a lot of teardown pics.  Can't wait to get the frame back and post up the projects progress.

thanks

If you locate the frame rails fare enough forword you do not have to do anything to the radiator mounts, just put the tab back on the frame where it was after instaling the rails. I mount the CDI in the stock location and the coil on the left side near the fuel valve. You have to get the coil inboard enough or it will interfear with after market radiator braces. I hope the pics help.

Doug,

On mine SH left the radiator in the stock location and modified the lower tank area (removed some of the lower tank to clear the frame rail) and repositioned the lower hose connection.

Other than geometry and looks, why put all the time and effort into going to an aluminum frame when it weighs more?  Just curious...

You said it all...Superior geometry and outstanding looks!

Plus all the aftermarket parts you can get for the bike.

Pure steering and handling.

It feels lighter in the air and more fliceble(or something like that).

And the looks/ coolnes of a AF

And much more mordern suspension.

All the reasons work for me.  Guess I should put the '07 CRF 450 frame to use this year

  Thanks fellas.

Thanks for the pics Jerry.    They will help out a lot.

Yes a lot of people tell me I am dumb to build such a bike.   Don't really care what others think.  Already have two KX500s I bought new.
Bought the 450 new.   It handles different.  To me for my weight it is very stable and straight tracking out of the box.    Just not a four stroke fan.  Stock motor had great power.  Was a 4 speed which is not exactly ideal for the desert.   Originally was going to use the 450 for the MX track, then ended up plating it up for the desert.    But like the two strokes so much, bought a leftover 05 and 07 KX250s in the crates for the MX track.   Plan to learn to ride MX a little better later on.   Maybe race in the older folks classes when my skills get a little better on jumps and such.

So while I can ride my 02 KX500 in the desert.  It will be nice to have the 450 conversion as a choice also.   Have a KDX200 for the tight technical and or woods.  And an older KX250 for track practice too.     Nice to have options!!

Did a lot of car engine swaps when I was younger.   Having a setup that not many others have is part of the intrigue.  Just located a car for my next project.  A Delorean.

We all see guys dump a ton of money in their new bikes only to sell them off cheap and start all over again with another.   We all need hobbies.

And I scoreds the motor! Thanks again!

My frame should be done in a week or two.   It sat at the machinist for quite awhile before he got time to get on it last week.   Will snap some pics when I drop off an ignition coil tomorrow.   Still looking for another KX500 for a motor, carb, throttlw and ignition.    Rest of the bike will be saved for a hill climb project.   Can't wait to put the bike together with the borrowed mockup motor and atleast have most of it sorted out.

Frame is about done.  He is finishing the head mount yet.    Will have to mod the one radiator yet myself.   Here are some pics from a week ago when he was welding the cradle  mounts on.

Man U are going to  have a nice bike when ur all done, But I am begging to think the 500 is to much bike, I almost looped my out a couple times at the track the other day, cant keep that front end down it comes up when it wants to!

[ToomanyKaws]

I have a 99, 02 and 04 KX500s.   So this 06 KXF conversion will make sort of four.    Frame is done, I just got to pick it up.    Looks like the radiator will be only real project.  Hopefully.  Going to use the stock gas tank for now and get a Service Honda pipe for it.    So the entire bike will be mocked up with this empty engine.

Picked up the frame yesterday and started putting some of the bike together.    Need to get a pipe, and work on the left radiator.  Then plumb everything up.
