Picked up two KDX's....

Recommended Posts

That's right....

My Brother from another mother and myself just went on a little road trip and picked up a couple KDX's on Friday.

One is a 1997 220 and the other is a 2003 220.... both bikes have fairly fresh top ends and came with Gnarley pipes/fmf sparky's. The best part was that we picked them up for under 2K total !

So I'm noticing that 32:1 on the mix seems to be pretty popular.... is there a reason to do this with the KDX? I've been running 50:1 in my KTM's without ever encountering an issue.... so whats the word?

Pick your ratio and stick to it, jet accordingly. 50:1 will be fine with good synthetic. The manual recommends 32:1. I'm currently running 40:1. As long as you jet it properly you shouldn't have any problem.

Might want to make sure those two "fresh top ends" are fresh, and done with Wiseco pistons and not stock. The OEM 220 pistons have a bad habit of destroying engines.

Congrats on the bikes! Sounds like a good deal.

I pay little to no attention to oil manufacturers recommendations, and more to the bike manufacturers recommendations. The KDX manual calls for 32:1. As long as it's jetted properly you'll be fine. It's been shown on a dyno that more oil makes more power in a 2t all the way down to about 18:1, provided that the bike is jetted for the ratio being run.

Interesting.... first that I have heard of that. I will have to look into this some more and run the same in my KTM (currently 50:1 Motul). We are planning a ride the first week of April at Mamoth Bar so the KTM will stay home this time.

Yeah, was told the same thing...more oil seals the rings to the cylinder better...like when doing a wet compression test.

      I have a problem with my stage 2 exhaust cam on my rmz whenever I kick it over the exhaust cam likes to stop at the lift unless I put it at tdc or kick it really slow it runs fine when it starts and I have played around with the shims right now all the valves are shimed and I have checked the timing everything’s to spec it just gets stuck at the exhuast I’m pretty sure it’s something to do with too much compression I probally will end upbuying stock cams but wanted to see if anyone knows how to fix this first

      I recently acquired a 1990 KDX200. The bike runs reasonably well for it's age. The first ride over 30 min the gearbox oil started overflowing into the airbox (overflow hose is routed to airbox). The oil that overflowed and the oil in the gearbox are an odd shade of dark forest green. The oil appeared to be overfilled slightly which explains the overflow. What I don't understand is the weird dark blueish greenish gray color of the oil.  I believe the PO used motul 10w40 ester gearbox oil because he gave me a half used gallon. I use Motul 710 2t oil which is blue, and run green coolant in the radiator. I drained the gearbox oil and there was a nice little clump of dark gray metalic paste on the magnetic drain plug, which should explain the gray hue. What I do not understand is the greenish blue hue. Anyone know what in the heck is going on with this old horse?
      The pic shows a sample of my drained oil. When held up to the light it turns more of a green color. Oil still feels slick as can be.

      will a clutch basket from a 98kx250 fit a 96kx250? How about the carb also?

      I have a new cylinder that i bought to rebuild my 1993 kawasaki kx250 with, because the old cylinder was destroyed. The guy said the cylinder is overbored a little but never gave us numbers. The new one i bought came with a piston thats been used and i would like to replace. I believe the piston that came with the cylinder is the correct size, but it very well could be off and i have no way of knowing. So how do i properly measure the cylinder bore, and how do i use this measurement to find what size piston I need to get?
       
      thanks,
