KX100 Squeaking Noise

2006 KX100

Hey guys my name is Theresa I'm new on ThumperTalk and I kind of need your help we just rebuilt the top end, the bike runs great BUT my son was riding yesterday after he got done we heard a squeaking noise seems like coming from motor it was loud, So just a few mins ago I start it back up to find out where it was coming from but no noise what so ever took it around the house nothing but when I was in first gear the bike seemed like it was over revving and felt like it didn't want to go 2nd gear same thing but a little better 3rd gear fine, can you please tell me what is going on with the bike I figure I will go ahead and get Clutch Pack I do need to change the transmission i'm over due on that but other then that the bike seems ok.

As for the squeaking noise, there's no telling and no way to tell without being there to hear it, but if it starts doing it again, shut it off and go hunting for the cause.. Best way to tell if the clutch is slipping is to get the bike going fast enough to get it into 5th gear, then rev the motor up and dump the clutch out, if the motor pulls right down, clutch is probably still good. If it isn't, it will let you know. If you do put new plates in it, while it is apart, have a look at the clutch basket fingers for notching. If they are notched much at all, it can cause a lot of clutch drag (bike trying to move with the clutch lever pulled in). When you get everything done and it's time to fill it with oil, I always recommend good 'ol ATF. Best stuff you can use in a 2 stroke transmission and cheap to boot.

Welcome to TT! :thumbsup:  


Welcome to the forums!


When you say "over revving" do you mean it fells like the bike isn't getting all it's power to the ground?


Sounds like a clutch issue. You're going to need to take the clutch cover off and have a look at it. You might get lucky and only need a new clutch pack but by the sounds of it you may also have a grooved basket.

Moose_338 & OLHILLBILLY , Thank You for the reply :) , I am going to take it apart this weekend to see what's going on I will definitely look at everything you guys mention, I will let you know what it was hopefully by Sunday.

      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.
      KX250 2002 $800-$1000?

      YZ125 2000 $1250

      KTM 400SX 2002 $1200

      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.
