KX100 Engine question.

Hey all. I just bought a 96 KX100. The guy said it was seized. So I brought it home and ripped her down. The jug and everything is find and no scoring. So I popped the side case off. There was quite a bit of white in there meaning water or coolant entry. I also noticed the teflon gear had some major damage to it looking like it was stripping and also had not been lined up for sometime. Now it seems the crank is free but every 10turns lets say using the kick start or spinning the clutch plates it hits this spot that seems to hold resistance. If you move it a bit backward then back forward again it goes away. I think the water pump went due to that teflon gear that is in the back of the turbine.

Anyone have any thoughts on this? I am trying to find out what the easiest way to check the crank bearings is and how to knwo if they are still good or not. The bike seized at idle and when I got it the kickstart was rock hard. It is no longer rock hard I can spin the crank with it no problem now.

Let me know your thoughts! Greatly appreciated!

I would replace the crank and bearings just because if it had water in there sitting it could corrode..so why not just change it.

      Hi all,
      I have a 2004 Kawasaki kx250 that died suddenly on me the other day. all i can get it to do is backfire every once in awhile. Tested the resistance and everything of the magneto and stator with a multi-meter and all is good.  Coil is new oem Kawasaki the reeds are brand new vforce and the top end and carb have been completely rebuilt.  key on crank is intact and all the timing marks are lined up. I hooked a timing light to it and spun the motor over really fast and found that it is sparking way to late.  The service manual says that it is supposed to fire 14 degrees before TDC but it is sparking way after TDC.  Im thinking its a fried CDI box since its the only thing i wasnt able to check.  Any help would be appreciated

      Hi all,
      I have a 2004 kx 250 2 stroke and it wont start.  it only backfires.  I was out riding it one day and came up to a stop so the bike was just idling and it started to try and die so i revved it up a few times then let it die and now it wont start back up.  It only pops or backfires when you kick it.  Its getting good spark and i just put a brand new plug and coil in it. I took the reeds apart and they look like they're brand new.  It was running great before so i dont know what happened.  Im thinking it could be a fuel problem even tho the plug is a little wet if you take it out after a bunch of kicking.  Any help would be greatly appreciated

      Alright, found three bikes all located where i live in Texas. I know they're all very different, but if you could tell me what you think each bike is worth, and which one would be the best deal. Thanks.
      Notes: Both 2 strokes have new top ends. I think the front brake lever is broken on the kawasaki.

      So I'm at a bit of a cross roads, I currently own a 06 rm250 and I love it. I also have a 02 kx250 which I'm selling with intent to buy a newer two stroke. I can't afford a newer ktm and the older ones aren't that great and kawasaki never impressed me. so I'm stuck between 06 yz250 and 05 cr250. I've heard the yz and rm after 06 are almost the same bike just the Suzuki handles better and the Yamaha has better suspension. So I'm not sure if I wanna buy carbon copy of my bike with slight differences. That's why I'm interested in a cr250 I heard the 02+ models RC valves are shit garbage but was mostly fixed in the 05-07 models. I ride at a track and at some bogs down the road from me. So from people who have owned both, what would you recommend. I know the cr is known for a hard hitting power band which I enjoy since im an aggressive rider. Should i just see which deal comes my way first.
