    YZ250 Stiff Clutch Pull

    FWIW, I've had way better success with OEM cables. Motion Pro has not impressed me on a couple different bikes now. Suzuki and Yamaha. Dirt and Street. Throttle and clutch. No more Motion Prop cables for me. OEM all the way. I got a $29 chinesium 1 finger easy pull clutch lever from Ebay. Just to see how crappy it was. That was a year ago, I love that thing!

    Push through and finish, or part it out and move on?

    Right, but you know what you have, and what it needs. A cylinder likely can be found reasonably priced, and I would run that case the way it is as long as it's not leaking fluid or air. I'd go ahead and fix it. You're not likely to find a used 2 stroke that doesn't need any work (as you mentioned) and YZ's are about the most common thing out there so parts are fairly cheap and plentiful in my experience. You've got $1k in it? Another $1k would likely get you a reliable beast to hammer on if you shop carefully. $2k for a good used bike is pretty good IMO. Doubt you'd end up any cheaper starting over.

    2017 yz 250 constantly fouling plugs. pilot jet?

    Yep, I've been to the plane crash a few times. I'll send you a PM. A few of us were planning to go ride next week. Maybe we could meet up. We usually ride from McGillivray but I know that whole area pretty good as well. I'm more than happy to help out with the jetting, but if his crank seized at low hours, that seems fishy. Doesn't seem right. YZs are pretty durable and I've seen lots of bottom ends go 300 hours without issue.

    2017 yz 250 constantly fouling plugs. pilot jet?

    I see you're in Alberta, and about 3000ft. That puts you in Calgary or Lethbridge maybe? I'm in Lethbridge but ride from 3000 to 6500 or so (Windy Ridge in the pass is about as high as I go). Mine's a 2016 250X so not identical but here's my experience: Bought the bike new. Loaded up badly and fouled a few plugs in the first 2-3 hours so I dropped the pilot from the stock 48 to 45 then 42. Not much improvement. Dropped the stock needle right to the bottom (raised clip to top). Not much improvement. Adjusted float 1mm PAST the factory range (increased float measurement/reduced fuel level. BINGO! No more loading up or fouling. Then I worked on the jetting to get it to run right. Here's what I've settled at, and I run it everywhere. Here at home, Temple Hill MX park in Raymond, in the mountains, and even at St Anthony dunes which are about 4500 ft: pj-42 Needle-Suzuki NECJ #2 MJ-165 (mostly, actually ran 168 in the dunes now that I think about it) as-1.25 turns out. mixed 40-1 usually Motul 710 but I ran Motul 800 at the dunes I haven't fouled a plug for the last 88 hours. Bike runs fastastically clean and crisp and gets excellent mileage. Top end looked perfect at 75 hours when I did the piston/rings. I know the regular 250 has more compression so this won't translate exactly but maybe its a start. It may seem like this is very lean on the main jet but remember I'm running the thin tip Suzuki needle so that is sort of like adding 2 sizes to the main jet. So like a 172 or so with the stock Yam needle.

    Newer YZ 250 X gear box-weak link?

    Near 100 hrs on mine as well. No issues. Regular (frequent) oil changes are important. Also, shifting firmly is important. No half-assed limp ankle stuff. They are known to be weak-ish, but as stated before they are good for 95% of people.

    YZ250X stalling

    Does it happen more when you go down hill? If it happens more when pointed downhill (with your bike in a front-down position) it's your float height that's too high. Drop your float height (actually increase float measurement/decrease fuel level in bowl) a couple mm and see if it improves. That fixed mine.
  7. I have sprayed with silicone spray in the past. Doesn't seem to collect dirt, but on a new tube with new cable, it really doesn't seem to show much benefit either. As above, clean and dry seems to be as good as anything.

    2004 CR250R with over 800hrs

    So...you figure? There's no actual hour meter on it? I feel like my bike should have more hours on it than it does, as in- it "seems" like I've ridden more than 85 hours since I've got it. I'd say it feels like 150 at least. But the hour meter I put on it before I even broke it in when it was fresh off the showroom floor says otherwise... Is he the original owner? 800 hours on a bottom end, if used gently and well maintained I can kind of sort of see - maybe. But 800 hours on an original piston and cylinder? That's a tough one to swallow. Not calling you (or your friend) a liar, but hour estimates and guesses can be a long way from accurate in my experience.

    2018 yz250x FMF GNARLY PIPE?

    For whatever reason, I think I'm the only one that has run a Gnarly on a 250X and not suffered anything significant on the top end. Better all over, with just a slight top end penalty. I love my Gnarly/PC296 combo.

    YZ250X - My first Hare Scramble!

    Yes, good points. At this point in the video I was already pretty tired... The first few KM of the course are not flagged until race day - it is impossible to know where it is unless you are one of the few that flag it. There are hundreds of intersecting trails in this area, it would be near impossible to actually find the course if you don't know where it is. But yes, that would help!

    YZ250X - My first Hare Scramble!

    Here's some poor quality video shot with a China gopro. It's what I have. Whatever, should be good enough to get the sense of the terrain. https://youtu.be/04AeKJi3t4A

    YZ250X - My first Hare Scramble!

    Lol no doubt. The field was likely more than 50% 2 stroke. And likely 70% KTM/Husky which is expected as —let’s be honest— they are very competent machines. But there was a very healthy contingent of blue bikes too. In truth I only used 1-3rd gears. Course was extremely tight, with lots of technical climbs/ descents. Lots of roots. Oh my gawd so many roots!

    YZ250X - My first Hare Scramble!

    So I did my very first race last weekend at the tender age of 42. Race was Sunday, today is Wednesday. Still feeling it but not too bad. Ran the 30th annual Porcupine XC race here in Southern Alberta. I ran in the beginner class, and took 2nd in class. I'm pretty pleased with that. The 250X ran absolutely flawlessly. I did lay it down in a fairly high speed section when I cross rutted. Pretty much destroyed my FMF Gnarly and tweaked a rad pretty good. I didn't really notice until the finish and the crash was about 30km in out of 56. Whatever, I've been wanting to try a Fatty anyway. Towards the end of my loop, a couple of the pros lapped me (on their second loop...). Those dudes are ON THE GAS! Not sure how they go so fast. Combination of skill and big brass balls I guess! Anyway, it was my first, but I'm thinking not my last! Race was put on by Lethbridge Motorcycle Club, and sanctioned by AMSA ( hopefully I got that right). I was really impressed with the professionalism and organization of the event. A hugely serious amount of work goes into these events, from the course layout and flagging, to the trophy presentation and site cleanup. Great job by all involved!

    99yz125 rear wheel issue

    Isolate the problem. Take off the wheel. Slide the axle through the wheel (with bearings and spacers in place. Does the axle fit snug? If not then it’s a problem with the bearing size or incorrect spacers perhaps. If it does fit snug then your problem is elsewhere.

    YZ250X first top end 73.6 hours

    Correct. Proper warm up is critical. Every time.
