Think ill have a go at this.
Starting with my 92 kx250, what runs fine, but i cant resist :evil:
kx500 engine showed up in the mail a few days ago, and it looks like it has one of those stealth bolts Kaw rider is selling, not sure though
From what ive gathered from this helpful site, ill be needing to the following:
Modify the swing arm
Modify the front mounting bracket and headstay
Make room with the gas tank
Get a cr500 pipe and weld on a kx inlet
Modify the air box?
Will post some pics when i start digging into it.
-
Got the engine in. Pretty straight forward, drilled the back of it to fit the larger swing arm shaft, and removes the front mounting bracket. im able to use the lower mount. Going to move my attention the front mount, then head stay.
man these things are beasts to turn over!!

Its surprising how well they fit in the 250 frame! Its like it was supposed to go in there. Good luck with it, its a fun project.

Progress!
Looks good so far Bro, Thanks for posting pics. You never know who will be looking for encouragement on their project.
Seeing someone else's fitment ideas has to be helpful.
You never know, someone may start to put together more "Kit" Pieces like J-Fab has made in the past for
AF conversions.

Thanks Tuck
Thats what im hopping for, aside from a personal archive

Went ahead and bought this pipe. Im I correct in thinking 89+ pipes will work?

yes that pipe will do the job 89+. take a look at my build http://www.kxriders.com/forums/index.php/topic,8032.0.html
if you read through it there is a link to torches build, i think his was a 92 as well. have a good read through both theres some good stuff in there

If it wasnt for this site, this project would definitely be alot more frustrating.
Got my headstay together, its not pretty but it should work. I take it the head stay is meant to absorb some kind of vibration or something? its the only thing i can think why they used aluminum plates rather than steel.

Pipe finally showed up, first seller said he "lost the pipe", week later got a refund, then Canada post goes on strike... anyways just waiting for a cr5 silencer now but in the meantime i can start chopping this thing up and making it work

Got some ride time in today :-D. beats me why you guys need more power out of these things!? what a rush.
i had to chop and weld the pipe in 5 places so i wouldnt recommend using a older fmf gnarly for this kind of project

-

dep pipe and 07 250f forks showed up. time to get to work
(http://i289.photobucket.com/albums/ll202/420longshot/IMAG0089.jpg)
-
Nice! Be sure to write back with the results, several guys (myself included) have heard of DEP but never saw the products, or how they compare to say an FMF or Pro-circuit pipe.

Will do tuck
the head stay bearings fit without any problem just needed to be shimmed. i also dropped off the front spindle at a local machine shop for them to modify enabling me to use my hub. will post some pics when i get progress
-
Pipe fit nice and snug, pleased with the fitment. it started to rust though so i clear coated it.
why buy a bike stand when you have a bucket, right?
(http://i289.photobucket.com/albums/ll202/420longshot/IMAG0104.jpg)
Got the fork stops worked out, should get my spindle back mon or tues, then ill begin mounting the caliper. also i seem to be missing the little rubber bits that mount the bar holder and i wont be able to order new ones for a while :-(

"why buy a bike stand when you have a bucket"
Ha-ha! I've only recently went to an old wooden box of sorts...
Been using buckets forever. My only advice would be to watch out during summer. I had a "Bucket fail" due to heat.
The garage got pretty hot, the bucket got soft and collapsed... only happened once in like 15 years... :|
It was the XR 600, Kinda the Pre- Big Red Pig
Pipe looks good and the forks just needed shims... good deal. Hope to hear a ride report soon!
Take care,
Tuck\o/

very curious about the dep pipe. Ive heard great things. Have you tried it out yet?
-
Very nice build. Makes me want to get my build going. I have had a 95 250 frame laying around for over a year now. I need to get in gear and find another K5 engine to start my build.
I'm interested in a review of the dep pipe as well.
-
The Dep has more of a mid and top pull with over rev, defiantly not as tractor like as the Gnarly. I noticed with this pipe its nearly impossible to ride wide open (any gear) on pavement, the front wheel pops up like nothing, Gnarly seemed a bit more tamed that way. And for the fork conversion holy cow, what a difference, just felt all around more stable at the front
(http://i289.photobucket.com/albums/ll202/420longshot/DSC01284.jpg)
-
That DEP is for a CR500 right?
-
Correct. Didnt think they made kx5 pipes?
-
how does the dep compare to the stock pipe. I feel like the gnarly (im assuming youre referring to woods pipe) has nothing up top at all. Ive heard that the dep has a very broad power band and pulls hard all over. Do you feel this is accurate?

Sorry extremely delayed reply *was hibernating over winter*. Yeah i can agree with it having a smooth power output all over the rpm range
starting digging into the engine for the first time and so fare ive concluded i need a replate job and crank rebuild for sure. debating having it ported as well but cant make up my mind :?. Any suggestions and what should be looked over when rebuilding the k5 eninge, open to mod suggestions too

Going to run a 01 kx250 ignition. from what ive read it will make it more snappy.. if its too extreme ill buy a hpi programmable ignition and or flywheel weight

Hmm two kinds of main seals to choose from. Both from MooseRacing
ones to left came with main bearings as a kit, and to the right was a complete engine seal kit. Should i just toss a coin?
