Need more Power
« on: July 30, 2008, 01:10:57 AM »
After a 6 month search I finally found a 500 in like new condition.  It's a 2001 and I already finished the suspension....Factory Connection of course!

I want to make some mods for more power.  I ride outdoor motocross or at least plan to!  What should I start with?  Pipe?  Is the FMF or the PRo Circuit better? Reeds?  Porting?  Somebody point me in the right direction!

Try the search button, that is usually a good start. This forum is full of good information on how to boost power.

Stock!  Don't touch a thing!  The KX has a great motor.  If you want to be competative in whatever class it is you're riding in, the stock motor is NEVER going to let you down or otherwise be a weakness.
#1  Suspension:  Sounds like you've taken care of that already
#2  Ergonomics:  You have to feel absolutely comfortable on your machine to ride it with 100% of your ability.  The KX has a very cramped feel for my 6'2" build.  But things any rider could benefit from are wider footpegs, extend the clutch actuating arm and I liked using a '89 KX250 gas tank.  It was a little slimer in the midsection.
#3  Gearing:  This is the only aspect of power you need to mess with.  IMO the KX (or CR even) comes geared too tall for todays MX tracks.  I'd use a 49t at a minimum, probably settle on a 50.  This would be far cheaper and more beneficial than any motor mods you could waste your time/money on.
Honestly, unless you don't mind looking like a dork put putting around on a 500.  Leave the motor alone and fix what you must to allow you to ride at the best of YOUR abilities.  You are not a faster rider than that motor is capable of going.

now that,s an advice  :-) i should take this advice to mind and let the engine stock,
my 94 k5 is stock and its like mick says you,r no faster then the bike will.
a.w. its one reliable engine engineered in japan,
and tuning is always cost increasing. no matter how you look at it.



better take a 700 cc maico if u need the horses to blast  :mrgreen:
