KDX 175 (1980) Kick Start "Free wheels" when kicked

Recommended Posts

Hey Thumpers,

My 1980 KDX175 no longer kicks! The lever works ok when turned by hand, but when you go to grab a foot full of kick lever, it freewheels, almost like there is no compression. There is compression though, the bike runs great when pull started. You can see the shaft turning, so it's not the lever. I suspect it is the mechanism. I have a manual, so I plan to tear into it this week. It looks like I can take the case cover off and access the kick lever mechanism and gears. I'll be sure and post the fix.

Anyone know of any common issues with mechanism? I plan to replace the lever with the short 125 lever while I'm at it as well, these old KDX levers are like butter!

Thanks all!

Well I wish I could add something of value here, but the damn thing just started working! I don't know what happened when we rode, but as I was prepared to tear into the case and check the kicker gear, I thought lets give it one more shot. Worked like a charm, kicked right over, all kinds of resistance, and pow she started right up. I have since replaced the kick lever with the one from my 2001 220 (which got the shorter lever from a KX125 - LOVE IT!), and it all seems to work great! Who knows whats up??? At this point I wont look a gift horse in the mouth (what the hell does that mean?!?) and hope she doesn't go back into free wheel mode. I thought it might have been heat and case oil, but the oil is new and issue happened 2-3 minutes into a ride, so it never got hot?

Oh well!

G'luck all!

      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.

      I am wondering how a kx125 will do at at Glaims. I am 14 years old 5 foot 4 inches  and 100 pounds. I will have a paddle tyre in the back too.

      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,
