  1. Hello everyone. First post here! Hope to stay active. Im making this post as I’ve read a lot about both bikes, checked several threads made here, but unfortunately I haven’t found anyone with similar intentions/riding style as I, to help make my decisions. To start off, a little background: I’m sort of a big dude, 6’1 205 lbs. I’m starting off my 20s and want to get myself a nice new bike. I got my first bike when I was 13 and I would consider myself an intermediate rider. Over the years of riding I’ve only owned a few bikes that lasted me quite while, started on an IT175, then a KX125, and my most recent bike I owned for 2 years was a 1990 XR250R. Bike was an absolute tank. I did ONLY trail riding, never raced and I don’t plan on it either. I’m currently healing due to a very severe compound tib fib fracture (non bike related) and I sold my bike not long ago. So, I have quite a while before I get another bike, and I figured while I’m healing it would be a good time to research and decide what bike would fit me best for when I’m ready to hit the trails again. My heart is set on a Yamaha. Either the YZ250X or the YZ250FX. I’m not crazy fast on trails, and I don’t get into any insanely difficult terrain most of the time. I ride around in silt “fields” and expansive trails that can get pretty rocky sometimes, and I’ll do an occasional hill climb. Northeast Pennsylvania to give you guys a rough idea. When I come out to an opening I will open the bike up, but most of the time I’m just cruising through the woods, so I still want some power. I’m not hard on the bike is what I’m trying to say. I was considering the WR250f but I’m not into lights, as I don’t ride at night and I have no plans on plating it. So that brings me to the two bikes in question. I’ve ridden 2 strokes before, and I don’t have experience on a 250 2 smoker, but like I’ve stated I’m more of a cruiser when it comes to the trails. Which is what had me eyeing up the 250fx. I heard great things about both bikes. That they’re both reliable. Maintenance is a concern here. I’ve done maintenance on both my 2 strokes and my only 4, but I understand older air cooled 4’s don’t need nearly as much maintenance as these MX styled 4 strokes. I know that routine Oil/Filter changes, and air filter cleanings will go a long way to help the longevity on any 4 stroke, as well as considering the fact I’ll probably never hit the rev limiter. My BIGGEST concern is top end rebuilds on the 4 stroke or catastrophic failure. Valve checks aren’t a concern as they seem simple enough. I have done a 2 stroke top end rebuild before and it wasn’t hard at all. Also I’ve heard 4 strokes like to overheat unless you’re constantly moving but I know the FX accepts a fan easily. Or is it even that big of an issue? The electric start on the FX is a big plus, considering my leg isn’t going to be to its fullest extent when healing’s over, but I would like kick in case something goes wrong with the electric. I’ve read that the FX has a very good electric start. Friends of mine have recommended the 4 because, well they all ride 4 strokes, and told me I can lug it when I want but the power is there. The thing that’s keeping me so torn between these two bikes is this. I’ve always liked 2 strokes and their sound/less expensive maintenance but I wouldn’t mind switching to a 4 MX styled bike, and I’ve heard nothing but good about the newer 250fx’s. Praise for both X bikes that is. So, with that mouthful being said, what bike do you guys think would suit me better? Thank you for reading!

    Top end rebuild

    Just ordered a oem top end kit for my 1999 YZ125. The bike runs perfectly, I'm just rebuilding for preventative measures. Is my cylinder nikasil plated? I ordered a ball hone since my cylinder is glazed. After some research I discovered that honing a two stroke cylinder isn't a good idea because of the ports. I'm taking my cylinder to get measured to see if I'm still in spec. I also will be measuring the ring gap with a feeler gage. Anything I'm missing to make this top end rebuild go flawlessly?

    2018 YZ250x Gas Mix Ratio

    I have a 2018 YZ250x that I use for trail riding and hill climbing, I can’t seem to find a good gas/oil mix ratio for the trails and was wanting some other opinions for this bike, Thanks!
  4. Has anyone tried using Athena power valves in an OEM cylinder? Everywhere it states "for Athena cylinder only", yet on Amazon, it states that they're good for both OEM and Athena applications. I've seen both (not side by side, unfortunately), and they looked pretty similar. Didn't take measurements, although I should've. I have read of people trying this but not actually running it. Just was wondering if anyone has experience with this. Thanks in advance!
  5. Hi guys, Picked up a 2000 YZ 125 in pretty good condition, but wanted to look into swapping out the Athena Factory kit on there with a OEM cylinder and head. I know the Athena kit uses their own power valves so I'll need to source the OEM ones, but all the other hardware is the same. Do power valves wear out, or am I safe buying a lightly used set on ebay for this part? The cylinder and head I'll be buying brand new. Thanks in advance guys. Edit: My goal is to basically restore this bike back to nearly new condition. I’m willing to spend some money, possibly more than it’s worth to some. Ultimately I wanted a rock solid green sticker 125 to thrash on all year so bear with me. Small airbox leak by previous owner let dirt into the boot so I’m doing a flush at the bare minimum. I have not even started the bike since I purchased and did my internal inspection. Splitting cases soon down the line to check and replace bearings and seals.

    2002 Yamaha YZ 125 Top End

    Hey TT! You all know me as that one annoying 15 year old kid that rides dirt bikes on the street for YouTube content. Well I bought a 2002 YZ 125 that had no compression, and I got it for cheap. So, today I fixed the float and went for a ride, but felt like enough was enough. I called my dad to come and help me take off the top end, and so we did. Be aware that I am a 15 year old kid, that has no experience with top ends, and am basing everything off one 17 minute YouTube video that was watched two weeks ago. Anyways, here's how it looks. Now here's my question... What size will I need to purchase? It is a 53.96 currently. Also, will I have to bore it out or is it good? Posted pics of the cyinder too. OR, I can do the 144cc kit. Eric Gorr is charging $450-$500 which is too much, any cheaper alternatives? Gary, where are you?? Two Stroke YZ Doc I need your help man! Thanks!

  9. I'm researching slider and chain guide combos and am leaning towards TM Designworks, but they seem to have multiple versions and to confuse things none of the retailers I've checked nor TMD's own website compares the various models, e.g., GP, Factory Edition, etc. Any suggestions?

    2003 YZ250

    NO HATE OR SMARTARSE. Hi all, i have recently bought a 2003 yz250. I have gotten it freighted so i have only looked at photos and a video of a start although, those don't prove much. I have a couple of questions if anyone can help me please do. If you have had the same year or similar and model please tell me what you ran? PLEASE NOTE - I LIVE IN AUSTRALIA. 1. Because i have gotten it freighted, the fuel has been drained. A mate wants to test the gears and some other stuff, so i am going to buy 3l of fuel to test, what ratio should i mix at and what fuel and oil should i use? 2. I'm riding in the bush with a couple of mates on 250 2 strokes, there will be quite alot of dirty,dust,rocks etc, what would be the best air filter and oil? 3. I wouldn't consider myself a pro rider but, I ride fairly hard, I want the bike to be healthy and in good condition. I don't want to replace the top end for at least 40+ hrs. What would be the best fuel to oil ratio, and what would be the best fuel and oil to mix with? 4. I plan on doing a top end, service, power valve and carb clean and maybe add v force reeds (if gears and the other stuff are good) Watched a couple youtube videos of top ends and they look easy, power valve looks a little hard but i think i can do it, have never cleaned a carb on a 250 so not sure what to do. If i added vforce reeds would it need to be jetted? (Don't know how to jet either) Think that is it for now. I LIVE IN AUSTRALIA.. Thank you

    2002 Yamaha YZ 125 Build

    Hey TT. I made a thread titiled "2002 Yamaha YZ125 Top End".But I am going to be doing more than a top end, so I made a new thread. YZ Doc has been very helpful by the way. While dissembling the bike, I saw that the Forks were leaking oil. Can I just run it or is that bad? How do I fix it? Let me know, thanks. Here's a pic of the bike when I bought it.
