help/info needed 00-05 kx 250 engines please

[nightninja_71]

hi
i am looking at the possability of running 2000-2005 kx 250 2 stroke in my 250 race/shifter kart.everyone else runs h***a but i want to be different and buck the trend,so i need your help.
the kart will be run on 1.5 to 2.5 mile tracks
what sort of power stock does the kx run at?
are the parts interchangeable between 00-05 motors?
are there any reliability issues ie cranks,gearboxes.a guy used to run a 98 kx250 motor but it kept breaking the gearbox.
has anyone used aftermarket ignition ie pvl sem selettra etc with success?
any help would be great,as i think this 'project' has got potential and have got approx 3 months to get ready cheers mick

Someone will probably know but maybe not much attention right now cause of Christmas? I have a question are you staying in a size class cause this website has a wealth of info on KX500 probably more than the KX250. Not that there is anything wrong with the 250. Good luck welcome to kxriders.

Ninja,
 I think what most guys do to check parts swapping fitment (as far as engine  componants)  is to log on to kawasaki.com or one of many of the retailers who have a parts diagram and simply look-up the part#'s and cross reference them.

  It would be nice to have some more 125 & 250 guys posting up,however it seems the 500 forums keep growing and the smaller bikes are hanging out somewhere else, for whatever reason.
 Good Luck,
  Tuck\o/

Is that the same class as in europe with those streamlined karts than sometimes go faster than F1???

What about TM racing??? They build kart engine's!

I think the KX250 engine is on par with the CR250.  In later years 2002 - 2005 the KX has more HP but I am sure none of the engines you are competing against are stock so the stock hp is not a deciding factor. I say go for it.  Besides, with the info on this site you can make it really fast.  Also, since many are making 250/500 hybrids there should be lots of newer 250 engines available. Hope this helps.

ps I made a cart once with a 2cyl rotax snomobile engine. It was scary.
