2001 Kx 250 compression

Recommended Posts

I just went out and checked the compression of my 2001 kx 250 and i got 210 PSI which I thought is over what they are supposed to have? I thought that the engine was stock when i got it the guy before me didnt know much about it. Is there a problem with compression being too high? I did notice when i got it it would ping when you got on it with normal 87 octane so I have always run 91 and it almost never pings anymore.

it will ping with 87, you should run 91 minimum. 210 is odd, i wouldnt worry about it.

I also have 210 psi on my 07 KX 250. That was checked with 2 different compression testers. I really have no idea how many hours on the top end either.

I checked my 95 with a new top end and it is 190 psi with both testers. Both bikes were checked cold.

I wouldn't get too caught up in the psi. But rather keep an eye on the psi from your baseline to determine when to replace the top end.

Thanks,

Jason

How do you like switching between the 95 and 07?

I like both bikes so far. The 95 seems like a small version of the 07. It is significantly smaller plus I have an IMS tank on the 07 so it makes it seem that much bigger. I'm just getting back into bikes again so my skill level is holding me back to give a really good review of comparing the bikes.

I'm riding trails, open fields between the woods and a few jumps. I feel like I have a little better control of the 95 so far, but they seem pretty much the same so far. The 07 has a FWW and the 95 doesn't and I think I like the feel without but I'm gonna get a bit more skill and them make a decision which way I like it.

Thanks,

Jason

I know I don't have a Kaw, but my 2000 250 (stock) has 230 psi and I have seen people with as much as 240.

I've had 94, 98, 00 and 05. The 05 is the best all-around package, even better since I lowered the suspension. The 94 does feel smaller, but I think it's the height that's the difference. I would take a 94-98 over an L model anyday. I just couldn't get comfortable on the 2000's.

I'm glad you decided to keep both of them. :ride:

I'm glad as well. It is nice to have a couple of bikes to play with and have a spare when you destroy the subframe on one of them.

I have to quit replying from my phone, that last post of mine was ridiculous.

Thanks,

Jason

      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,
