    Ive had few WR125s in the past and have been a long time member here. Ive been riding other bigger bikes but couldnt stay away and picked up another 2013 Wr125 a couple of months ago.
    I thought Id share my recent experiences getting back into a smaller bike again

    Bike was a low hours bike owner by an older gent (even older than me)

    I rode and it felt pretty ordinary . Big bog and weak power but ok at top .
    It was all orginal and still on its original piston.
    Played with the power valve arm - didnt do anything .
    Richened the needle height that helped a bit.
    Put the RM needle in with a #5 slide and put on an old 39mm Mikuni I had with the RB designs divider plate mod and hey - now we are talking .. Big power increase in the middle to top end .
    Jetting 460 main with 40 pilot . I would possibly try 470 main but dont have one .
    Put a new piston and rings ( Id say 10 hrs old ) in with a .3mm base gasket and now its feels great.
    Compression was down at around 120 and now at around 155

    Felt it was maybe a tad rich down low and tried a 32.5 pilot and still pulls well. Less spooge.

    Had quite a few rides and really loving this bike .
    The top end power is surprisingly strong - even though I've had wr125s, 144s , 165s .
    I love the feel of 125 motor size. Its sounds great and gets a lot of comments.
    The handling is just fantastic . I really feel so confident on it and that means I ride it a lot faster in the tighter tracks than say the ktm 350 , fe450 or te250 2t , wr300 I have been riding .
    The steering is so good and I can push it in the corners much harder. So much fun.
    Ive put a stiffer rear spring on and all it really needs now is possibly shorter gearing - say a 52 rear.
    I will post any other big improvements .:thumbsup:

    I own that model. I never rode mine with the stock muffler, changed it out to the spark arrestor model FMF. Bike always ran great all the way through the range, so I never did any jetting changes to it. The 52 will turn the bike into a willing climber, as the stock one allows the bike to bog on sandy, steep inclines.

    The weak spot with the standard needle seems to be mid range - if you are happy with it then thats good. I might try standard needle/slide again with bigger carb to compare.
    I carry a bit more weight than you so I need to make as much power/torque as I can

    The 52 may allow me to run in 2nd gear up some hills which is always better for momentum . 1st will spin up too easily . The only concern if you do need to use 1st from the start of the hill its a bit too low. Cant get speed needed that longer first does .

    You have a great bike there. I've had three of them myself. Excellent platform and rock solid.

    Looks like a wonderful motorcycle you picked up.

    I’ve recently been riding my ‘12 WR144 after a long while letting it sit since I purchased a Beta 300 Xtrainer. These are wonderful bikes: handle great, decent low fir a small bore, and rip up in rpm’s. Makes me smile just to see it in garage, let alone ride.

    Just gave some love: swingarm bearings & new sprockets & chain. After 100 hours on ring & piston compression is still 150.

    Ive been running Maxima Caster oil - cos it smells nice haha. Got to leave those 4 strokes behind me something to nice smell. Seems to spooge quite a bit at 35 to 40 to 1 . But I dont mind it . I dont think Amsoil is available here

    I am tossing up whether to put a CR ignition on it that I have been storing for 6 years or so . I kind of like how it feels now .

    Ive found the standard pipes are good and silencer also for trail riding

    Ive just fitted some V4r reeds - will see how they go

    I am looking at fitting a Hydraulic clutch kit .

    I used a Magura kit on mine. Had a slave crap out on me once but has been pretty solid otherwise. Super smooth and easy pull with the Midwest lever.
