    250 XC Suspension Settings For MX

    What would you guys suggest for sag and fork height settings. I see a ton of people going with 105mm on sag now, and didn’t know if I should go to that, or stick at 100mm. As for stiffer springs for my level of riding ability would it be necessary? Would just bumping the clickers up higher compensate enough? I’m by no means hitting any crazy jumps or anything.

    Yea I was working and just skimmed through your post and saw AER48. Then after reading it again I understood what you were getting at. My bad on that.

    Appreciate the response, but my bike is a 2012 and has the dual cartridge forks, I believe. Wouldn’t mind having the AER forks though! [emoji4]

    250 XC Suspension Settings For MX

    I bought a 250 XC because me and my buddy’s do a mix of trail and track riding, figuring it would be a good medium. But lately we have been putting more time on tracks and I can’t get the bike comfortable for track riding. The bike is a 2012 and I just wanted to see what you guys that track ride the XC are doing for suspension setup. I am about 180lbs in gear with stock springs and maybe a C class rider at best haha. Currently my sag is at 100mm and the clickers on everything are set to “sport” according to the owners manual. Also I have the forks up 2mm in the clamps. So any input is greatly appreciated. I’ve always had mx bikes up to this point and after riding my buddies SX I just feel more at home on it. So hopefully I can get this close or should I just look to go back to an mx bike. Thanks!

    2000 KX250 Kickstarter Kicking Back Really Bad!

    Alright guys, so made all the changes as mentioned above and now it’s worse than before. Bike still kicks back and now I’m pretty sure when trying to bump start it, it is trying to run backwards. So I am not the most savvy person on the electronics part of a dirt bike, so please help educate me. So with what’s going on I have a feeling there is a short in the stator, or pick up coil. It’s the only electrical piece that was moved before the problem got worse. So am I correct in my thinking or does the regulator, ignition coil, or CDI have any bearing on the timing? Also if one of these components are bad will it take out one or the other components? Sorry but if someone could explain how each component functions exactly and what to look for and test would be greatly appreciated!

    Thanks kxrob for the input! I just ordered a carb rebuild kit and new choke plunger. So I’m just going to get it back to stock for the time being for a base line and adjust from there. My main concern is just resolving this issue with it kicking back. So I’m hoping with eliminating the massive pilot jet and the gap between the expansion chamber and muffler will cure that problem. I’m also installing a new woodruff key for good measure. If those two things don’t work I’m kind of out of ideas.....

    So tore the bike back down and here is my findings. Electrical. Stator and pick up coil were with in the resistance specs Primary and secondary windings on the ignition coil where in the resistance specs. Voltage regulator was with in the resistance specs. Fmf fatty and turbine core had a pretty decent gap where they meet. So I fitted the stock exhaust and has a tight fit where they meet. Checked the reeds. Which gaskets, reeds, and boot all looked good. Checked in the cylinder on the exhaust and intake port and everything looked good. Timing is lined up according to the manual and when I removed the fly wheel it was still on the woodruff key. Air gap was also set on the pick up coil according to the manual. I did find some unusual jetting going on though. Stock Main-158 Pilot- 52 Needle- N3WE Clip- 3rd notch from top Currently in the bike Main- 155 Pilot- 62 Needle- N3WE Clip- 2 notch from top Now I have never seen someone go up that large on the pilot jet. So maybe the culprit? Spark plug Ngk br7es So what I am going to do is get a carb rebuild and go back to stock with everything. Plus a new choke plunger as the current one is a little finicky. Get the recommended spark plug and a new woodruff key for good measure. Also on the pick up coil it looks like the fly wheel kissed it at one point and shaved a little of it off. Would this pose a problem if it tested ok? Picture show damage

    So we tried retarding the timing on the stator and still had the same results. Also ran a compression test and it maxed at 150psi. So haven’t made much progress. Does anyone know what’s up with the different flywheels offered for the 00 KX250? I will post a picture of the fiche diagram. You can see in the lower right that they offered an option flywheel. The bike currently has the style that is on the right side. I didn’t know if anyone knew what the difference was and if it maybe part of my problem?

    Checked the reeds and there was no chips, or frays in the pedals and could not see any day light through them. Also installed a new boot on the reed cage as the old one was cracked and dry rotted.

    So small update, got the air gap set on the pick up coil, but didn’t fix the problem. Bump started it again and it ran good, however when I would pull the clutch in it would idle up some on its own. Also if I was in first gear it would run without giving it gas and the clutch out. So now I’m thinking possible air leak or float level not adjusted correctly. But would either of those issues cause the kickstarter to kick back hard? Well either way this weekend I’m gonna strip the bike down go over everything in the carb, check throttle cable routing and do a compression test on it. Any other suggestions on what to check or look for while I got her apart would be appreciated!

    Thank you for the reply broken.biker! Good info on the piston! I actually just read an article about that in MXA or Dirt Bike Magazine! However I do believe I have the piston installed correctly. The arrow on top is pointing towards the exhaust port and the window on the piston is on the intake side. The rings were aligned with the pins in the piston ring grooves. So I don’t believe that to be the issue. Now when you are referring to “arms” around the magneto are you talking about the pick up coil? Because there is an “air gap” that needs to be set between the flywheel and the pick up coil that I was going to check and set today.
  12. So I bought a 2000 KX250 that wasn’t running and had a sheared off kickstart shaft. The previous owner said he had a lot of electrical work done on the bike and said that he rode it once and sheared the kickstart shaft and couldn’t bump start the bike. I tore the bike down completely and found the big end bearing took a dump. Which I figured was what caused the kickshaft to shear. So I rebuilt the entire motor. New crank and transmission bearings. New hot rod crank, standard compression vertex piston, and all new gaskets. Everything was torqued to the manual specs. I have got the bike to run but like every other time I kick it over the kickstart will kick back ungodly hard. It has ruined a pair of sneakers, Carolina work boots, and almost put a hole in my aplinestar riding boots. Along with leaving my foot pretty black and blue. I’ve owned numerous 250 two strokes, ktm 380, and a CR500 that didn’t even come close to this thing. What I have checked: 1. Stator timing marks are aligned 2. Flywheel is aligned with woodruff key on crank 3. Kickstarter ratchet punch marks are aligned (new shaft) 4. Have tried a different CDI box So Ive looked around the internet and have found people with similar problems but no one seems to have a solution. The new kickshaft splines have twisted and there is gaps where it’s starting to separate from the shaft. Which I have installed yet another shaft and it has done the same thing. So I did bump start the bike today and it ran good, but I could not get it started again after that. Sorry for writing a book but Just want to be thorough. So I’m at a loss, if you guys have any input I would greatly appreciate it! Thanks in advance.

    Why would oil leak frome here?

    Sorry part of my response got cut off. But it could be oil leaking from the center case gasket.

    That shaft goes through the rear of the engine cases. I’d pull the shaft and see if you have oil in the middle of the shaft that is running the shaft out to the nut.
  15. I just purchased 2012 250 XC and I’m looking to get some new plastics for it. To my understanding I should be able to swap all the plastics from the 2016 XC on to it correct? I know the front fender needs an adapter but I was curious what is the newest fork guards i can put on it? Also I’m kind of hung up on the plastic color I want to go with. I’m between the flo orange and the 2016 ktm orange. I’m having a hard time finding some good comparison pictures online between the two. So if anyone has pictures of the two colors side by side that they could post up it would be greatly appreciated! Also give your guys opinions on what you prefer. Thanks!
