Decomp lever sticks, any solutions?

Every time my son crashes on our 05 CRF250X, it is hard to start and sometimes will not turn over. I charged the battery, but it only helped a little. When this happened before, I took off the valve cover and found the decomp lever stuck. I play with it a little, and it frees up and everything is fine. So my question is, should I replace the decomp lever, the cam, or both?

The bolt is tight, so rule that one out.

Perhaps just a new return spring would fix it up.

recoil spring..........maybe, thats what i tht could be.

I don't thinks so. The spring works after it is freed up, just sticks. It would take a big spring to free it up after it jams. I might just change the cam and decomp lever as no one seems to know which one to replace. I guess I am the only one that has ever had this problem.

I've never heard of it before. I wonder why a crash would cause that and not just shutting the bike off when you are done riding.

I would try a compression test and see if its realy more than the 57psi stated in the manual, or if maybe you have a week starter or something. The decomp. unit is pretty simple, There isn't much for it to get stuck on unless its bent.Good luck, let us know once you fiqure it out.

It seems to be the side to side hits that do it. It tends to stick outboard to the right. Once freed up, it is in just a smidge inboard. Something is allowing the decomp lever to move. I did have the engine blow up a few years ago (valve let go and took everything out with it). I did not change the cam or cam parts, so maybe something got jacked up back then and now that the battery is 4 years old, it may be getting tired and can't overcome the increased compression from the dry rebuild.

That is really strange. I wonder if there is an issue with your bolt. I would try that 1st if you don't want to buy a entire cam assembly.

      I enjoy riding flowing single track and double track with some small technical sections, nothing insane. I'm also way too cheap to spend thousands of $$$ every riding season on maintenance and rebuilds. I've owned a dual sport 1987 XL185 that was underpowered but predictable and a 1991 YZ125 that was overpowering and exhausting in technical stuff (though I'm not a fan of 2-stroke exhaust and noise).
      I'm 6'1" and 200 lbs with riding gear.
      I've narrowed down my choices to Honda CRF250L (heavy and underpowered but low maintenance), Honda CRF250X (smooth power but expensive maintenance), Husky TE250 (smooth power and easier maintenance than CRF250X), Husky WR125 (super light weight and easy maintenance but 2-stroke) and KDX200 (cheap, lightweight but 2-stroke).
      I realize that the CRF250L is more road oriented and closer to my vintage XL185 - I'm considering putting on more aggressive tires and raising the bars. I like that the CRF250L engine has a 8,000km service interval though it is greatly underpowered. I don't mind trailering a bike, so road worthiness is not a deal breaker. I'm concerned the CRF250L will be cramped for my 6'1" size and I've read that the rear suspension is too soft and sags significantly for anyone over 180 lbs.
      The CRF250X seems like the best choice for single track and woods riding but I've read that rebuilds can be expensive and complicated. I've ridden the CRF250X a few times and it feels slightly bogged down at lower rpm.
      The TE250 frame and design look easier for rebuild/maintenance and people have said it is more agile (I've raced mountain bikes most of my life so I appreciate a maneuverable bike).
      I'm only considering the 2-stroke WR125 and KDX200 because they are super lightweight and should have a smoother power delivery and better low-end grunt than my old YZ125 on the trails. I'm not a fan of the sound or smell of 2-strokes but if it makes the riding experience that much better I would consider a 2-stroke.
      Hoping to get some feedback before the spring riding season.

      I am currently in the thought process of purchasing a crf250x and converting to supermoto to get it registered for road use. Just wondering if anyone has converted and what tips you would have for me to maybe make it easier? I already have a set of SM wheels off my drz that will fit with new spacers.
      Any advice will help!

      Has anyone fitted grease nipples to the rear suspension component and swing arm to CRF250X? Compared with my old XR350R, is ain’t a step backwards not being able to grease the CRF.

      So I’ve got a 09 crf250x and from every angle I’ve been shouted that the airbox mod will be the best thing in world along with a jd jetting kit. At this time I’ll being using the stock exhaust, so I’m wondering if doing these mods will void the registerablilty of the bike. I’m in nsw Australia. Also, anyone with experience with this mod, does it make it louder? As that is the main issue with getting is registered. I’m planning on doing the mod this afternoon so if someone could let me know ASAP that’d be awesome  cheers

      I'm tearing down my '06 CRF250X for winter prep. I checked the spark plug (see pics).
      I've rode with this plug for most of the summer. I'm thinking it's a bit rich, so for the other 250X owners out there, what jetting are you running/what do you think I should run? The only mods I've done is install the JD Jet Kit (165 main, 42 pilot, Red needle 4th clip, and thick o-ring), FMF Q4, and 4" x 4" hole in air box (with No Toil Super Flo Kit). The bike seems to run alright, but should I drop a few on the main jet?
