4/16/2022 8:30am I have a problem with my front brake (yz250f 2017). When i brake into big braking bumps or brake right after landing from a big jump, front brake loses pressure and i need to pull it more. To be more precise, the enganging point of the brake change, the lever gets closer to the bars in order to stop than...

4/16/2022 8:30am Bad news guys. I put a new braided brake line and a front caliper rebuild kit, and the problem isnt solved. Only happens in big braking bumps or braking after a big landing. In the road i can go 5th gear pinned and hit the brakes, and it works perfect. Something is wrong with the caliper. It seems that when...

3/27/2022 12:30pm update no2. I pulled the caliper of the wheel and i found out that the pistons dont move evenly. The upper piston moves half the distance of the lower piston , with each pump of the brake. Also the front wheel doesnt move freely, it has some drag. I swapped my front wheel with my buddy's yz250f and my wheel...

3/26/2022 12:18pm A little update. Yesterday i bled the brakes using the pump and crack method and also tried something else. I pushed the caliper in order to fully compress the pistons and push the air, if there was any, up in the master cylinder. So i noticed some bubbles coming up and then the lever felt harder to pull. So i...
mikeglg Started a new thread Acerbis skid plate for YZ250F 14-18
3/17/2022 6:02am I bought the plastic acerbis skid plate for my bike (yz250f 2016) but it seems that i cant mount it good enough. It comes of the bike when i hit big jumps.The problem is that the bracket turns and becomes vertical, because no matter how much i tighten the screw, if i push the skid plate towards the engine, it...

3/8/2022 11:22pm When it starts to lose firmness, it lasts until i complete braking and leave the brakes.The next moment i hit the brakes (next turn) , it has returned to normal.

3/8/2022 10:04am I have rebuilt it and it became stronger in general, but the problem remained. I bleed the system using the classic way, pumping and cracking the bleed screw until i have firm feeling on the lever. Also i have done the zip tie trick a lot of times which also improved general power but never solved the problem. It seems...

3/8/2022 7:51am In a brief check i did rotor didnt seem bend. I will check it again. I have bleed the brakes many times, changed fluids, zip-tie overnight. One time i zip tied the lever fully pulled in, i noticed that it leaked fluid from the master cylinders banjo bolt.
mikeglg Started a new thread YZ250F hitting neutral when downshifting from 3rd to 2nd
3/4/2022 3:07pm Hello. I have a very weird problem with my bike, yz250f 2016. A lot of times when i downshift from 3rd to 2nd, it goes straight to neutral and If i downshift again i hit 1st, so its the "true" neutral. I have changed the 3rd-5th shift fork because it was very worn out, and the 3rd gear cause it...
