My crappy worn out 89' KX500
« on: May 30, 2004, 08:44:18 AM »
Hi, Just wanted to say that this is a pretty sweet site. I wanted to post some stuff about my bike just to see what you guys thought lol. I have a 89' KX500 with a slightly dented fmf pipe w/ the silencer. It has a 4'' over swing arm. I also have brand new V-Force Reeds in it. It has been resleeved to .5mm over(14cc increase?) but i had to steal the old rings off of my brother's stock 500. So the rings are .5mm too small haha. I have a light weight flywheel(not sure how light). It has been jetted The bottom end seems to be going out because it rattles like crazy(way more than my brothers 94' kx500). Funny thing is that my bike is still faster than my brother's kx5(newly resleeved w/ new piston) unless i lose traction, then he is riding wheelies past me haha. My friend's cr500(1.5mm over piston but pretty rough cylinder walls and piston) but he still cant keep up. Id like to see your comments as to what you think. It's still a pretty bad a$$ machine. I plan to go up to 1mm over and rebuild the bottom end. Cant wait for that!

Sounds cool.  The vibration, as I'm sure you know comes as standard equipment on the KX!  My 94 was pretty rough and turned out to be a worn crank jounal.  I replaced that and it's much nicer.  I also suppose that with the light flywheel you'll get alot more vibration.  I run a Steahly 14oz weight on mine and it removes quite a bit of the vibes.  You've got a great bike.  It just needs some money!  I had mine bored 2mm over which is approximately 520cc and I like it so far.

i realize the vibrations are part of the kx500's but this is some serious vibrations after riding it for like 15 minutes your forearms are worn out. im 6'3'' 230lbs and pretty strong and its hard for me to hold on in the motocross courses. My suspension is screwed too so that doesnt help haha. thanks for the imput.

crank needs to be trued and bearings replaced.  If you keep riding it the bearings could oblong the steel where the bearings press into.  Bottom line is you better look into to it quick.

Hey Kawdude, thanks. I have a question for ya. Do you know how much it would cost to have the crank trued and the bearings replaced? An estimate is cool. I have about $800 saved up to fix everything on the bike. Thanks again man.

Send it to forward motion (http://www.eric-gorr.com/).  I sent my crank there and it cost about 120 for the truing and it made a world of difference.  That is the cheapest cost I've found but there may be others.  Gore is very well known in the industry though.   They can do the bearings also but I did it myself so I'm not sure what the cost is.  Gowen may know???  He had some lower end work done there.  If you chose to dIY buy the bearings from this joint...http://www.honda-kawasaki.com/ . This is cheapest OEM parts place I've found.  It's slow because they order the part rec'v it and then ship to me but the cost is excellent compared to my local dealers.  Some parts i've priced there are half the cost!!!

I sent off my entire engine there, including a crank costed me roughly $1020. That was for a 520cc top-end porting, complete lower end rebuilding + new crank and hot rods ect. ect. Also some welding. Because you do not need a new crank (mine had rusted and pitted from being under water) it will be $700-$800! Including the top-end.

Looking at my bill here is the cost for the lower-end parts and labor NOT including the crank:

Engine Rebuilding with Crank Works  (Truing) - $175 ** Labor
Moose Racing Main Bearings and Seals + Hot Rod Kit - $150 * Parts
Oem Tranny Bearings and Seals - $75 * Parts

I'm happy, you will ALWAYS have vibes with a 500, but I've found that pro tapers and solid mounts are the key to that!

Kawdude is right on!  8)
