  1. I have a 2019 yz250x. There is a wire going to the carb and I am wondering what it is and can I remove it to take the carb out. If it is tps will it have to be reset.
  2. Ok I know I know another jetting thread.... but never played with 2 stroke bikes to much, more of the 2 stroke sleds, anyway the bike seemed rich from the get go I'll be riding 2000-3000ft. Currently dropped the main to 175, 48 pilot, stock needle position, stock power jet, 1 turn out on airscrew, do you think that 175 main is to lean for the elevation bought 60 degrees out? Also mid to top end is great pulls hard.....0-1/4 throttle stutters a little, leaner pilot or turn out air screw? Any input appreciated thanks.
  3. We got any YZ250x riders in OK with good baseline jetting? I picked up a 2019 model. The previous owner of course "jetted" it by running 50:1. I never understand why people think they successfully jet their bike by adding fuel and taking away oil, but none the less, this thing is fat and like to get it back to 32:1 like most bikes are recommended to run. Upon digging through the items he gave me, I discovered I have the optional jets as well as the extra (leaner) needle. My initial thought was to just go straight to the 175 main and 45 pilot. I know this will elp, but thought I'd ask to see if others in the area have got theirs dialed in yet. I'm aware of the 40 power jet which I do plan to do, but for the time being, was curious which of the optional jets I already have works best for others preferably in my area
  4. I remember that the 250X pipe is supposed to be more narrow and tucked away, but I'm not sure in what ways. When I look up part numbers for replacements all the part numbers are the same between the 250 and the 250X except for OEM part numbers. So it looks like the only way to get a 250X pipe is to go OEM? Previous bikes I've always bought some SRT pipes to have as spares, but what are the difference between the YZ and YZX pipes and does it matter? FMF $269.99 250X: 024054 250: 024054 Pro Circuit $262.46 250X: PY05250P 250: PY05250P SRT $174.99 250X: SRT00469 250: SRT00469 OEM 250X: 1P8-14610-10-00 $272.99 250: 1P8-14610-00-00 $225.41
  5. I replaced my stick clutch plates with tusk competition plates and now my 2019 yz250x feels like a 125 I have to rev it a lot to get any power out of it. I did not put in heavy duty springs but I didn't think it was necessary any help would be appreciated. I race open A and actually use my clutch throughout the corner.
  6. Anyone know the nut size for the bolt that runs thru the swingarm and motor, should really grease those bearings while I am stuck at home.
  7. Hey guys, so I just rebuilt the top end of my yz250x. It started up just fine, but once I started revving it, it made this whining noise, so I shut it right off. I over tightened the powervalve bolt that has a 6 on it when I put it together, so I loosened it and then made it only torqued it slightly, noice was instantly gone and I went and rode the bike for a half hour without any issues or noise again, so my question is, could that bolt being over torqued really cause a louder whining noise?
  8. Hello All, I am looking at possibly buying a used 2017 YZ250X or a new 2019 or 2020 model. Does anybody know if Yamaha made any changes to the bike from 2017-2020? Thanks for any feedback or input.
  9. Last item to buy for my new yz250x is some radiator guards. Im really unsure of what to get. It seems BPD is the best but at $400 cdn I don't know if I can justify that right now. I watched a review from a guy that installed the Unabiker guards and he said they didn't fit great and had to drill etc etc. Im looking for something that's going to give me good protection, fits and is a little easier on the pocket book.
  10. So I ran over some branches and bent my front rotor, which caused me to lose my front brake. I ordered a new rotor and could not get pressure regardless of bleeding or back bleeding. I could literally fill the MC from the caliper by back bleeding and still no pressure. I figured it was the line and it probably got a mild rip causing air to get in...so I replaced the line. I still don't have pressure. I think I narrowed the issue down to the MC. It is not moving any fluid. You can see from the picture that the MC is full and the line is completely disconnected. The fluid should drain out, but it does not. Nothing changes when I pull or adjust the lever in any way. Fluid is not moving from the MC...this is brand new bike 2020 YZ250x with under 15 hours.
  11. Dumped the bike on a steep rocky section. Due to the stock pipe being tucked in so snug to the engine, it pushed the pipe into the water pump neck and cut the hose. Be sure and look em over after a good spill. I was over heating near the end of the ride but no damage incurred. The system was 20oz low but fortunately I was running a reservoir with about 6oz to draw from. That perhaps bought me about 15 minutes. If your trails include rock gardens you may want to get a one piece skid plate/pipe guard, or run the gnarly as it has more clearance.
  12. Hey I had a quick question guys , on the newer YZ’s the fork covers have a integrated Yamaha logo on them which actually comes out the cover about 1/4 inch . I wanted to know if you guys would think this would cause an issue when installing graphics over it ? Wanna see if possibly someone has had this same issue before I buy new covers without needing to.
  13. Hey just thought I’d share some info and pictures on my 250x I picked up back in September. I have a bunch of trails And single track right behind my house which gives me no excuse to why I’m Currently only at 6 hours but that’ll change once the weather breaks. Currently have a bunch of Mods and clean “ bling “ it. Loving the bike , but due to rich jetting I haven’t gotten the full experience because I’m fouling plugs whenever I’m not ringing it out or I’m in the technical stuff too long but you guys have helped me a lot on what to do to properly jet in another forum, but here are some pictures and list of “ mods “. - Gnarly Pipe - GYTR Turbine Core 2 Silencer - Full Works Connection Clutch/Perch Assembly ( Stock cast lever bent then snapped after first 2 falls) - Boynsen Ignition and Clutch Covers - Acerbis Handguards, Brake Guard, Chain Slide, Frame Guard, Skid Plate -Polisport Swingarm Protectors - Works Connection Bling.. Rotating Clamps, Oil Cap, Resevoirs - Gripper Seat - GYTR Hour Meter - Free Flo Hose
  14. So had some issues recently and hoping this makes sense. I just put a new top end in my yz250x along with fixing my power valve that had a guide pop off the top side and locked it up. I fist noticed a few weeks ago that my bike seemed to have more of a hit when it came into the powerband which I didn't remember it having after I did the powervalve mod a year ago. Had some friends ride my bike as well and they complained it had less torque then the kx100 we had with us. When I did the top end I seen that the powervalve was locked up so I figured when I fixed it I would gain more low end torque yet I notice no difference down low afterwards. Just before the new top end I had to try hard to keep the front end down thru the first 3 gears but after I only have to do that in first. Now I'm not sure if the bike felt more powerful before because it had more of a hit which would lift the wheel easier or I'm actually down on power. To go along with that I also replaced my throttle cable which had the outer layer cracked. Unfortunately messed up and didn't have the plastic piece set properly in the carb. It seemed to move fine when I set the throttle free play but as soon as I started the bike and revved it just a bit the cable jammed up and the bike basically went full throttle and took a few second for the kill switch to do its job. I'm not sure what kind of damage that could've done to the rings since nothing was broke in yet. The bike seems to run just fine otherwise and I don't have a compression tester to see if anything is off there. So I guess I'm looking for input on how other yz250x bikes feel after the powervalve mod to see if mines messed up now and if I toasted my rings. Hopefully that all makes sense.
  15. I have a 2021 yz250x that has about 85 hours I looked at my tack metor and saw Iv hit up to 11k rpm is this to high if so did this hurt my engine?
  16. Hey, I’m new to the forum, but I just purchased my 2020 yz250x back in March of this year and let me start by saying it’s an absolute trail beast, but this last weekend I went riding and was “fouling” plugs like crazy... so I thought... the next day my buddy and I went out I had to do the walk of shame back to the truck since my bike died and would not start again. When I got home I dug into it a little deeper, and found I had no spark whatsoever and if I did, it was incredibly weak. I grabbed my owners manual and followed the trouble shooting steps with my multimeter and everything checked out perfectly to spec. The manual says if everything checks out, then replace the CDI unit and test everything again. Well, I ordered one and it won’t be here for another week or so, but I’m sitting here and was wanting to reach out to other folks who may know something that I don’t, doll I’m open to any ideas. I know a lot of you are probably going to say it’s the stator, and it’s quite possible, but the resistance was perfectly in spec according to the manual, so I’m not too convinced that that’s the culprit. I also went a step further to check for continuity between all of the connections and the main harness connector and every wire including the grounds ringed out. I’ve swapped out multiple new and used spark plugs (br8eg) and it’s the same result, either weak spark or none at all. Anybody have any ideas? Thanks
  17. Reading lots of recommended mods for the 2020 YZ250X and see lots of guys recommend the G2 throttle cam. In some posts, guys are referring to it as the throttle tamer. I google around and noticed those are both seperate products. What does what, and which should I get? The cam seems more expensive. Learning each day so I apologize if this comes off as a dumb question. Oh... And what the hell is a Jimmy Twister and do I need it? g2's site recommended it. I do lots of tight trail riding so I wasn't sure if I should replace the throttle or just go for a FWW. I appreciate any input!
  18. I have been using the rekluse z start pro for many years on my 06 YZ250 and moved it to my 16 YZ250X 4 years ago. I'm thinking of getting the radius cx and would love to here from anyone that has done this same switch and was it worth it? Thanks
  19. After reinstalling my carb into the bike, I forgot to plug these 2 cables back. I wrote the bike for 2-3 hours with them unplugged. Did I cause any damage? What do those cables even do?
  20. My wife's uncle has 1982 IT465J that he is willing to sell me. I've only looked at it and you going to try and kick the motor over this coming weekend. It has been garage kept and not started in about 7 years. Just from looks it looks almost like new and the chain looks like it was changed out yesterday even though it is also at least 7 years old. What would be a good offer price? Thanks
  21. so i set my float at 7.5 mm and ran it for a while then noticed slight gas dripping out of overflow from carb when parked in garage. took it apart again did not leak until it sat for about a week, its been really hot and humid in the 80 almost 90 here in pa. Could it be from the heat or or do I need to set it a tad higher?
  22. I want to buy a clutch cover for my 2018 YAMAHA YZ 250X. What do buddies suggest to me? Which is the most resistant and beauty? https://www.ebay.com/itm/Boyesen-Clutch-Right-Side-Crankcase-Crank-Case-Cover-Yamaha-YZ250-YZ-250-X-99-18/192766151573?fits=Model%3AYZ250&epid=171142106&hash=item2ce1c20b95:g:gIQAAOSwlx9cHRIg http://www.boyesen.com/works-billet-factory-racing-clutch-covers-4.html https://hinsonracing.com/product/billetproof-clutch-cover-yamaha-yz250x-2016/ https://www.motosport.com/gytr-billet-clutch-cover?variant[GYT0017]=GYT0017-X001-Y007 https://www.ebay.com/itm/Tusk-Billet-Aluminum-Clutch-Cover-Black-YAMAHA-YZ250-YZ250X-2001-2019-yz-250-/173746044311 Other suggestions? Thanks.
  23. Hey guys, I have a 2019 yz250x which I love but i think it’s time I raise the bars a bit, lower the pegs and eventually get a seat. After a long ride yesterday I was pretty worn out from being hunched over and also always felt like I was too far over the bars. i love the fastway pegs but they all say they don’t work in the lower position on Yamahas. Spent quite a bit of time looking for proper pegs, does anyone else with a 250x have lower pegs? If so which brand please! thanks in advance!
  24. I bought a 2020 YZ250X a week ago today and I'm having issues with the shifter. On my second day riding it, I couldn't get it to downshift and the shifter had a "dead" feeling, for lack of better term. It would click up one gear but wouldn't go down. If I stopped and finagled with it for a few minutes it would eventually work, I went through this twice before calling it a day. Took it to the dealer and told them I think the shift spring came loose (I've had a similar thing happen on a KX125 several years ago). I picked the bike up today and the service guy said the shift spring (hopefully I'm calling that by the correct term) was put in backwards(?) and it's good to go. After riding a turn track for a pretty good while with it working perfectly, the shifter went dead again. Same exact thing - shifter feels "dead" when trying to click down a gear but will click up once. I can't find neutral and if I start it and try to take off I can definitely tell it's in a higher gear, same thing as last time. The dealer is an hour away and didn't fix it correctly the first time (or was that the second time... would that be something assembled after they uncrate it?), so I'm going to take a gander at it myself because I need to be up and running 100% by next weekend. I'm hoping it is actually something as simple as the spring behind the clutch basket and not something deeper in the bottom end causing this issue. Any ideas? Things to look for? Tips and tricks when doing this work? I know there's thousands of this same bike out there so any help would be awesome!
  25. Who uses a 100 rear vs 110 for off-road? I have always run 110/18 and at least in Dunlop they are very wide. I tried another bike (different brand) with a 100 rear and it handled so nice. Do u guys think a YZ250X can get away with a 100 rear? I am talking technical off-road.
