    More top end KX250

    My '93 is strong though the entire band, only at very low throttle does it bog much and everything is stock other than the reeds. And I can't remember what kind but I know I didn't spend big bucks on them. Are you having a hard time with your bike?

    When to do a top end?

    When I was racing I'd replace my top end and all gaskets every 3 to 6 hours on the bike. Now, depending on how often I ride and how hard I'm up to probably 12 to 15 hours. It just doesn't cost that much, keeps things tight, and gives you a chance to keep the valves in great working order.
  4. I'm looking to step down from my '93 KX 250 to a 125 again after riding my friends '98 KX 125. It was fun to finally be able to throw the bike around again for a change versus the bike throwing me around. I'm looking for advice on what years to avoid if any. There is a nice 2003 on Craigslist that I'm somewhat interested in checking out and got to thinking hmmm maybe I should ask the folks on here what they think. Someone mentioned avoiding the kx's that had the "bladder" forks? Not sure what that means but its' stuff like this that I'm looking for. Thanks!

    '93 KX 250 Question

    Update: I took the forks back to the shop and he agreed to take another look at the left one. Took it totally apart and noticed the rebound piston didn't fit as tight in the cartridge as the right one but that was it. He showed me the valve assembly and how you can't take it apart without breaking the seal the factory puts on them holding them together. I called Race Tech and described the problem I was having to ask if new valves might fix my problem. They rock btw...the guy was awesome. He said that for some reason the valve is checked open preventing the rebound and compression valves from closing at the right time to make them work right. He suggested taking the valves apart and cleaning it out totally and wasn't concerned with the sealed threads the factory puts on them. But bottom line, he did not suggest that new valves would solve the problem. The fork is still not working correctly, I did not buy new valves. Good news is that the shop didn't charge me anything for digging back into them. So I'm in the market for a used pair of forks for a '93 kx250 *hint hint*
  6. Anyone have a set of forks or just a fork cap they are willing to part with off of a '93 KX250? My left fork is in need of desperate attention. The dampener rod came loose from the fork cap and ruined the threads on it. Could also use the entire rod/valve assembly.

    '93 KX 250 Question

    Well, I got my forks back. The right fork feels great...when I adjust the clickers and squish it manually(not installed on the bike yet) I can feel both compression and rebound dampening occurring. You can hear oil being squished thru the valve. The left fork bounces with very little oil squishing sound. No amount of adjustment on the rebound or compression seem to make a difference at all The guy at the bike shop said they both looked good and are nice and tight still. Let me ask you this, does he have to remove all the inerds when replacing the seal and changing the oil? I mean do they take everything out nad clean it up real good or can you replace the seals without taking stuff out? It seems as if I could get this left fork to work properly I'd have some nice suspension up front. THis has probably been my problem all along!

    '93 KX 250 Question

    Yeah I just checked Race Tech's calculator too. .44 kg/mm is what they recommend but the stock spring is .41 kg/mm....does .03 kg/mm really make that big of a difference for $150 or whatever the price will be? BTW, I just called the shop and this guy has been in business for YEARS and doesn't know a whole lot about forks other than changing the oil and seals. Bummer... How can you work on that many bikes and not pick up on tips and tricks for this kind of stuff?

    '93 KX 250 Question

    You think I need stiffer springs? How would that smooth out the ride? I'd think it would make them bounce back even quicker....or feel a little harsher on the compression...hmmmm

    '93 KX 250 Question

    Took them to a normal dealer close to me, recommended shop. I still have the stock springs in them. Haven't ever felt the need to mess with it. I'm 6'5" and weigh probably somewhere around 210 with my gear on. I was asking about Race Tech products to have the guy install them that has my forks now. Not sending them into Race Tech as I don't want to put out that much cash.

    '93 KX 250 Question

    Hmmm well I just took them in to have the seals replaced and asked the guy to check everything for wear...I'm open to replacing anything worn. But at this time I have not made the decision to revalve them. If I were to, would you all recommend Race Tech?

    '93 KX 250 Question

    Ahh so maybe a rebuild to begin with might do the trick. I can work on every other piece of this bike and replace the top end every 6 to 12 hours depending on how I'm riding, but when it comes to suspension I've never been around anyone that does their own, so I've not learned. I would rather have someone go through it with me the first few times rather than try and follow a service manual and end up screwing something up because I don't know the practical big picture of how all that stuff works. It's such a vital part of my bike I do not want to mess with it.

    '93 KX 250 Question

    Any chance a revalve might help? Any aftermarket products provide a bit smoother ride? Or are you saying these forks on this year bike just aren't great period?

    '93 KX 250 Question

    I've always taken my forks in for oil changes/seal replacements (wish I knew enough to do this on my own). I've never been happy with the feel of the front forks on this bike. I've tried running slightly higher oil volume in them without any improvement. I've worked hard with the clickers and taken a ton of time to really test each setting without finding a desired result. Basically they don't feel plush at all. They seem too bouncy and I've bottomed them a few times. I run a tie down around one of my slider tubes to measure how far they've traveled when I ride and once in awhile I'll bottom them out but they mostly come within an inch of that. I guess it's good to get lots of travel out of your forks but I've ridden other bikes and felt way more comfortable and confident just because of how the suspension worked. Would a revalve be something to consider here? What might help me smooth out my suspension? BTW, I used to race back in the early 90's and bought this bike new in '93 so I'm somewhat intimate with it Thanks, #68

    Front fork maintenance would be awesome. I hate taking them in for service, I'd love to be able to do them myself.
