YZ125X My new YZ125X!

[Livnpaintball]

So I sold my 2018 KTM300XCW because I realized I’m no Graham Jarvis, it was had to admit but I finally came to terms with it. So I bought the little Zinger to help get me back into the swing of things. First real mod will be springs, they are too stiff for my old carcass and weight. Next might be the tires. The pic is before my first ride!

Is that an aftermarket ignition cover on the 125X?

Acerbis covers, go over the stock ones.

You will probably love your new yz125x. I have 49 hours on my new yz125x and have loved every minute of it. 

Here's the great day I brought it home last summer.

I had to drop the float level down some and install a number 35 pilot jet to prevent plug fouling.

What is your weight? You must be a fly-weight if you need softer springs.

150, I want to try out Race Tech’s recommend weight.

Nice! I need to check my plug. I put a break in hour on it yesterday and have some adjustments to make.

What’s your sag numbers with the stock springs?

Congrats on the awesome new bike. Going to be different than that 300 but I bet you will love it. Are you in north Texas?

I think you are going to be fine with the stock springs.  That bike is softly sprung as is.  Like MANIAC said, check you sag numbers.  You should be right in the ball park.

RIGHT ON!!!! I have as much fun on a Monkey as I do on a full size bike!

I think I was looking at this bike!  Congrats

Nice bike!  My brother and I really like our 125’s for trail riding.  His a 2020 YZ125X, and mine a 125XC.

My brother weighs 160lbs soaking wet, and the stock springs/valving really work well for his style of trail riding in the Pacific Northwest.  Thus I suspect that the stock springs and valving will be close for you as well.

Re the carb that comes with the bike - Mikuni 38mm TMX.  The carb comes jetted way to rich for the bike when doing slower speed trail riding. So you may want to consider a 35 or 32.5 pilot.  Also the jet block gaskets on these carbs are know to fail pretty quickly (as I recall mine failed at under 10 hours), thus I would replace the jet block gasket with one from JD Jetting (about 20 bucks with shipping).  Otherwise you will be chasing your tail trying to jet the bike.

Anyways, Congrats on the new bike.  I think that Yamaha did a great job in building a fantastic small bore trail bike with the 125X.

What kind of terrain are you riding that the 125 will be easier?  125x will be a blast, but aren’t many full size bikes that are easier to ride than your old 300.

50mm front and 100mm rear, swapped out the front springs and it’s 60mm in the front now.

I also thought the 300 was a handful so I went with a 250XCW.

Or why not a 150XCW with e start and counterbalancer?

Congrats on the new bike though, I think you will enjoy the 125.

I use to be a HP freak but now I like small an nimble, I have a Surron X and it’s a hoot to ride on MTB trails.

The 300 felt heavy to me and a tad to tall, I ride mostly single track. But I do miss it.
