KX450F - KX500 conversion

[dpindet]

Hello All,

Here are some quick pics of my latest conversion. I am using a 2006 KX450F and installing a 1998 KX500 motor. So far, everything has been pretty straight forward. I did have some help from Jerry @ JFab Motorsports. He sold me the cradle tubes. Let me know what you think and I will keep updating this post as I progress. Anybody know how I can get my hands on one of SH's pipes? I have called and emailed with no luck. Thanks

Very nice use of the old forged "Y" section. I take a slightly different approach but it looks real good and will have a nice factory look when finnished. With what looks to be real tallent skip the SH pipe and modify a PC or FMF from a KX500 and have a real custom part. Great job!

I think a very succesful "Y" could be built out of some 1/4" flat pieces of sheet. I wish I had a frame to mod just to do a post on my idea. Very nice work, now lets see some beads. No pressure LOL

Two problems I encountered with the pipe on my 2008 Service Honda KXF450R.

#1: The bend/loop covers the flywheel,  removal of the cover or flywheel requires removal of the pipe.  It also interferers with the use of my E-Line coil.  I'll have to have a different pipe if I want to use the coil.

#2:  Service Honda utilizes the right rear fender bolt to mount their muffler.  I will have to relocate the mufflers mount to the original subframe muffler mount to enable me to install the rack.
I must say Service Honda made their pipe for a specific use. 
It looks, mounts and works great for moto-cross.
I use mine more like an enduro so I have to make a few changes.

I used the 1/4" plates on mine and it worked great, 1 yr. of riding and no problems, also I bought a SH FMF pipe and works great.

Round one at the welders is complete. Today the frame rails we completed. Now I gotta get the motor mounts and everything else fabbed up and tacked together. Here is where we are at so far, and just started a few weeks ago !

Got a little more done this week. The pipe is all ready to be finished welded. I used a CR500 pipe and put the KX nose on it, along with a few other adjustments/tweaks. The CR silencer bolted right up to the rear fender mount. I will probably just roll with that though. Here are a few pics. Like how I incorporated the KX's air box vent into the KXF airbox?

Man, you don't mess around.   Lots of progress in a relatively short period of time!   Looks GOOD!

The last of the welding on the frame was done today. Here are some updated pics.

If you dont mind me asking, what did this cost you so far? i just want to get a rough estimate of how much im going to end up paying when i convert my k5.


Thanx

I think I am around the $3000 mark. That is buying both bikes and selling off parts too. I bought a set of DNA wheels though, and that was $500.
