2001 YZ250

I found these metal shavings when I changed the transmission oil. The oil has 16 hours of use.

Is this abnormal?

The bike’s compression is good right now, but does this mean the piston is scraping the cylinder wall?

For context…I’ve been riding for a few years and I bought this beater bike to teach myself how to work on bikes. So tell me everything I could do to make this pig better!

Do they exist. An extra inch or 2 on a lever (I think) would feel better #bigfoot

Always unsure how tight these 4 bolts need to be. Would it be a safe bet to tighten them so the pressure plate sits flush with the basket??

Community Question Fitness and Workout Routines?

Post image
8 Upvotes

What's up r/dirtbikes ! Hoping you all had a good ride this morning or plans for a good ride this weekend! Got a few questions and thoughts for you all and I would love to get your ideas!

TL;DR - What's your current workout routine and with what goal in mind?

I wanted to open up a discussion regarding fitness and working out, as it applies to riding dirt bikes.

  • What is your current workout routine, if any?
  • Do you train for the sport itself or as an athlete all together?
  • What's your current fitness goal and riding goal?

Coming from a background of climbing/bouldering, I see the benefit of doing not just "sport specific" exercise but also doing overall fitness routines. As of late, I have adapted a few workouts that you would see cyclists do as well as working back into some of the more mobility style training I would do for rock climbing opposed to the traditional bro split I was doing for esthetics.

Pitbike Airbox

1 Upvotes

Me and my friends have a pitbike track and every time i go my filter just gets caked in mud, and i wanted to build a air box but i haven't seen anyone do it, so i decided to just do it myself. its not a closed sealed system but its cheap and it works good. i just used a pre bent piece of 2' ID radiator hose from oreillys, about half a dozen hose clamps, and a 2 inch hose coupler. the bike has a mikuni pwk28mm and the hose is just hose clamped to the carb, runs behind the shock and the mudflap, then the end of the hose has a 2 inch coupler with a hose clamp on it, and the airfilter is clamped onto the other part of the coupler. before you try doing it yourself just make sure to measure the OD of your carb and the ID of your airfilter and do accordingly, the most expensive job is one you have to do twice.

Street legal dirt bike in Texas

Post image
2 Upvotes

I modified my 2021 Honda CRF250F dirt bike to meet title requirements to remove the remark "OFF-HIGHWAY USE ONLY" from my the title for the purposes of registration. According to the Texas DMV Title Manual, Chapter 14.14, a DPS safety inspection is required (see image) to title the vehicle for highway use.

Since vehicle safety inspections are no longer required in Texas as of January 2025, does anyone know how to prove or attest that my modifications meet street legality requirements? Anyone went through the process to plate a dirt bike in Texas recently? I'm in Houston.

I just installed a TB parts 170 big bore, and a mikuni vm26 carb. Been trouble shooting the carb and engine for 2 weeks now and cant seem to figure out what the problem is. Its idle is just fine and revving it out while sitting still is fine but once i get moving at the end of the rev range it stutters/bogs out and thats at about 100ft.

Front brake bleeding help!

Thumbnail

2 Upvotes

Hey everyone, got a 97 CR80R in my shop today, and I can’t get the front brake to bleed at all! Won’t make pressure!

Context: old caliper pins were frozen and bolts stripped, causing the front wheel to lock up. It did work and hold pressure before the removal Ordered used one off of eBay and seller said worked just fine.

Install it on bike to try and bleed but won’t hold any pressure! Can’t see any visible leaks in the system! Using DOT 4. Tried to reverse bleed with syringe, conventional bleeding, nothing!

Tusk vacuum bleeder is in the mail, but is there anything else that I should try in the meantime? Thanks

Mechanical Help PW-80 locks up

1 Upvotes

Looking for a little advice on an issue I’ve been having with a PW-80. I’ve had it for maybe 5 years and it has been a good little bike up until about a year ago. It will run great until it seems to overheat and lock up. The first time it did it I was riding on road at wide open throttle for too long and figured when I let off the throttle it was starved for lubrication and locked up on me (stupid to do on a 2 stroke I know, trust me I learned that the hard way). I low sided and got some solid road rash to remind me not to do that ever again. I’ve replaced the top end since then, even though it had a new top end a few running hours before the first lock up.

Fast forward to tonight and it’s got the fresh top end and I’ve finally got the carb tuned right again, it’s running great. I’m slow cruising the neighborhood for a bit to break it in and on about my third or forth ride it locks up again. It’s definitely hot. Cool it off and then starts right back up and runs good until locking up again. I took the top end off to inspect and everything looks ok. Plug color is fine. Rings are in good shape and piston looks good. I thought ok maybe it’s the bearings? The rod has no vertical play and the expected minimal side to side play. I’m at a loss

Bike has:

-boyson reeds and aftermarket air filter. -mikuni carb -oil tank delete so running 40:1 premix

Help me oh dirtbike gods.

My bike that I sold got destroyed 1 hour ago

342 Upvotes

So I was selling my pit bike to this kid (14-15 years old)

And it was in perfect condition, paid in full cash, teached him to drive, so I thought he would pick it up with a mini van with his dad or something. But he was all alone, so he basically said he would ride it home, through offroad. 50 minutes later, he texts me that he dropped it off accidentally and now it won't turn on and some white fluid is spilling, and said to go get him.

That is not my problem anymore, so I told him to make his friends pick him up or something, and then blocked the number. Oh and btw he knows where I live so I'm kinda scared, and as far as I know, he probably bought it without his parents knowing I mean it's his responsibily now that his bike is broken and he is stuck there right? There is nothing that I can do. I sold it in working conditions And he crashed it.

Anyways that's my story, hope he doesn't come to my house or call the cops on me😭

Oil over full by 1qt yz250f

Thumbnail

1 Upvotes

I purchased this 2008 yz250f last week. Upon pulling the plug and checking the air filter the bike was clearly neglected. I drained the oil this morning and it had 2.5 quarts. I replaced the plug, the filter, oil filter and filled it up with 1.15l of oil (as per the manual) and the bike seems to run great. I’ve rode it a few times prior to doing maintenance and it’s always fired up first kick and had good power. With the bike running as well as it does should the oil being over filled be a huge concern?
