4/25/2025 8:36am That is certainly a bit more affordable. I may try that first. Thank you 🙏 Edit: Just ordered a couple. Gonna put one on the boy's 250 as well 👍

4/25/2025 8:18am Yeah, I know people get grumpy when they spend a bunch of $ on sexy parts only to realize their bike performs worse than it did before, but I think it's pretty common in the moto world to want to throw money at stuff. It's a lot like Golf. No amount of swing trainers or hybrid clubs are gonna compensate...

4/25/2025 7:51am Finally! This will solve a lot of phantom issues with your YZs fellas, so grab one even if you haven't yet dealt with issues related to a kinked vent hose. Yamaha needs to take notes and make this happen stock ASAP

4/24/2025 7:37am I'm not doubting that there may be benefits to running an aftermarket pipe if you have something specific you're after, but cutting one down purely for aesthetics is wild to me when the bikes are so good stock. I'm the weirdo outlier in this space though for sure. I'm 50. Vet B rider on my best days, And I weigh...

4/25/2025 8:38am Which is why it’s crazy to me that so many folks are so willing to spend time, effort, and money to make their bike work objectively worse. We need all the help we can get, dawg. Don’t make it harder on yourself

4/23/2025 7:04pm Looks sweet, but nothing will convince me that this works better than a stock pipe. I appreciate all you guys supporting the industry that we all love so much 👍

4/22/2025 11:07am I am pretty sure I know exactly what you're dealing with as I just went through it myself. I changed a bunch of stuff as well and nothing fixed it. The bike would run like a poorly jetted carbed bike and would feel like it wanted to die on me when off throttle, mainly when it would get hot. It...

3/5/2025 3:31pm Ah, I see. I've had one go bad on this gen bike before as well. Something they did with the motor design does seem to make them a bit more unreliable, but the good news is it's a quick and easy fix.

3/5/2025 2:50pm Are you referring to the countershaft sprocket seal?

here is the part keefer talked about replacing on one of his podcasts the stock one is plastic and will deform/melt when it gets hot and cause problems, and it sounds like your problems are related to long hot motos. the injectors on all modern bikes are so small even the smallest particles can gunk them up. ive run one of these in my tank since day one and havent had any starting/running issues that many other people in my riding group have had. cheap and preventative. https://www.motosport.com/product/?code=SS-M-G-P-NA-PLA-DIRT&key=Twin-A… https://www.gizmoperformance.com/product-page/gizmo-mods-yz450f-tempera…

3/5/2025 9:46am Yeah, it really only presents when the bike is hot, which leads me to assume it's some sort of sensor. That plastic part is something I've seen melt before so likely a good investment either way, but that part doesn't include the sensor as well, does it? I assumed that was just the elbow fitting. That fuel filter is interesting...

3/5/2025 9:42am Definitely tough to diagnose online. Ideally I was hoping to find some folks who may have had similar symptoms and had resolved their own issues. I do appreciate the suggestions though 👍

Handlebar switch may have gotten moisture inside and corrosion. Pretty common. Also may be getting low fuel pressure. I like the idea about the coolant temp sensor also. Cheap and easy to rule out.

It was on one of his podcasts a while back, not recently. Send me a PM. Might be able to help you out on the ECU.
