Put your 2 cents here...please

Ok guys.... heres the deal.... The Kx is old but still has some good life left in her.
Sure she has been abuse for 15 years now, but she still throws dirt on my buddies when I need her too. My funds are short this summer (and probably this winter also) so I was thinkin of tearin her down this winter and puttin some life back in her. Im bored and have the time to spend on it. So I guess what I need input on is , do I save my money and get something a little less out dated and run the kx till she dies, or put my funds into her as they come untill shes all she ever wanted to be... If I did save the kx Ide go frame up...... new polished case.....new everything. I havent ridden many newer bikes... just an 02 and 03 cr250... And compared to the kx they arent all that.... sure the plastics have cooler shape and the seats were a little skinnier.. but not the huge difference I would expect between a $5000 CR250 and a $650 KX250. Any input would be appreciated, I realise its probably mostly prefrence.... and I would like to hear yours.... keep in mind, what every owner of a piped 02-07 bike would think when they see an older kx pull up to the line. I would probably think.... this is gonna be easy.Thanks Guys

few minor tweaks will keep the KX in the game. but if your planning to get into racing an updated bike would be the ticket. for a trail rider the kx is plenty

engine mods like vforce3reeds pro circuit pipe and cylinder porting also new meats and suspension updates

265 big bore, porting, 38mm carb, pro curcuit pipe, VForce reeds, michellin star cross tires, new chain and sprockets (2 up on the rear). Not many other bikes out there are gonna compete with that. What year is your bike? looks like a 96.

its a 92.... when i got it...it was pretty beaten. So far I got a used back wheel (so I could ride it) new front black plastic (planning on going all black) uni filter, msr aluminum bars throttle tube grips. Im getting a pro circut platnum pipe within the next couple weeks, after that Im boring, sleeving and porting. Also got a new swingarm I havent put on yet. Thanks to Bikebandit.com I will be kinda piecing this thing together. each payday...I will be sure to take pics of all mods as they come.

If you sleeve it have the porting done 1st then have them match the sleeve to the porting. You should talk to Denny about it (I could be wrong) but L.A. Sleeve did the proting on my old race bike and then matched the sleeve and flow polished it. It was absolutley beautiful. Insane power... hands down the best money I ever wrapped into that bike. Get rid of your tiny little carb and put a PWK 38mm carb on it. You will be totally impressed by the bigger carb when you get it jetted out. Your engine will rev out much better, the pro circuit pipe is a top end pipe anyway so the bigger carb will really help.

I was told yesterday that the platinum pipe was lo-mid pipe by a fella who claimed to be sponsored by pro circuit....

Don't hold your breath on that one, lol

Doesn't a Kx come with a 38mm pwk???

Well I personally would buy a 90-96 KX250 motor if I could find a good deal.

Have you ever split the cases? The lower end won't last forever but it depends on how much you ride and how clean you keep the filter and so on.

How much of the work can you do on your own? That can save big bucks.

There should be big bore/ stroke kits out there. Corey Sprock or Eric Gorr maybe? 265-310cc? A 310cc would likely need case mods and be costly but it would be brutal. Hell a KX500 Motor will fit too.

But a top end steel sleeve with porting, v-force reeds, pipe, new carb needles/seat, wouldn't break the bank.

If you take the stator cover off and pull up and down /side to side and there is any movement at all then I would replace the main bearings and rebuild the crank.
