    WR250F 2016 piston change at 206 hours

    At 80hrs I replaced my top end on my 2015 WR250F. I used the 2016 YZ250F piston kit which has a DLC coated pin. I'm about to do my 2nd top end as i'm at 160hrs now. This time i'll replace the cam chain as well. I upgraded the piston oil jet at 80hrs with the 2016 yz250f part as well. I hope to do the top end this week, It will be interesting to see how everything looks inside at 160hrs.

    WR250F 2018 piston in a 2016

    The 18 piston has a smaller skirt, has different casting ribs underneath, pin to top of flat outside edge of piston is different measurement & the shape on top of piston is different.

    WR250F 2018 piston in a 2016

    Gday Guy, i have a 2015 wr250f that i fitted a oem piston kit part #1SM-116A0-01. This kit had piston #1sm-11631-01, gudgon #1sm-11633-00 & rings #1sm-11603-00. This was the 2015 Yz250f piston kit with the gudgen pin DLC coated. I have had a look at another piston kit which is for a 2016-18 yzf and 2018 wr250f. The kit is #1sm-116a0-10 & the parts are, piston #1sm-11631-10, gudgen #1sm-11633-20, rings #1sm-11603-00. The rings are still unchanged since 2014yz250f & 2015wr250f. The piston part # is changed saying it won't fit a 2015 wrf & the gudgen is changed as well. When looking at the 2018 and 2015 piston sided by side there are a few differences which make me say the 18 piston will not work properly in the 15 motor. I changed to the later oil jet part # 1sm-15155-10, for better gudgen lubefication. Cheers chris

    2015 WR250F front brake upgrade?

    Any oversized disk is the best bang for buck with the 2015 wr250f. I have a GYTR 270mm on mine 👍👍

    Gday MM could you please do a bit of a story on what you did to make the KYB forks fit and did you change anything inside the forks? Cheers

    Internally lowering shock

    As a rule of thumb, 3mm spacer equals 10mm lower rear. I've had my 2015 wr250f lowered 10mm but still need to run 108mm sag. If i want 105mm sag i still need a 1mm spacer added. Stock i was running 120mm sag to get the chassis balanced to were i liked it.

    WR/YZFX 2015+ top end schedule?

    Actually I looked in my log book and I fitted the new top end at 85hrs. Next top end will be at about 150hrs and will be the updated 2016-18 yz250f piston kit.

    WR/YZFX 2015+ top end schedule?

    I did 100hrs in 10mths on my 2015 wr250f before I fitted the OEM piston kit. The gudgen was the most worn part and this looked to be caused by lack of oil. I fitted the 2016-18 oil jet because it sprays more oil at the gudgen pin. I have kept the old top end so I can compare next time.

    WR450F 2016 Turns Itself On

    My mates 2017 wr450f is priming it self and if you push the stop button you can hear relays are clicking on and off. We have tried 2 different stop and start buttons but it is still the same. We think its the main starting relay that is under fuel tank and has the red tape on wire. I'm ordering a new relay today we should be able to try it this weekend.

    2015 wr breather hose

    Yeah I could just leave it but i won't, lol. I don't want the hot oily air to be pumped into the inlet tract and into the starter motor.
