    Out of the box yx150 gpx 150 or 155z

    So iam doin a transplant on my dhz 125 and not sure which of the 3 to choose from i no these motors have been covered seperately on here and other mini pages but im in 2 minds about choosing between them im really looking for something to bolt on and rip with a tbolt bbk at some point my previous yx140 is still going strong after almost 5 years
    And the z160 crapped the gearbox and other issues multiple times so kinda scares me about a z155 but heard lots of good things about all the motors so i guess id like to no what the better option is?
    Oh and i ride my bikes hard af like most of the boys obviously after there properly run in
    Any help would be appreciated ps sorry for all the questions ��

    i ride my bikes hard too...all or nothing and have had issues with the zho engines aswell!, always seems to be 2nd gear, yet have never caused any damage to the gearbox itself!!
    always turns out to be bent shift-forks....
    I think its my fault though as the clutch constantly needs adjusting as it heats up and you keep riding, but it only takes once to shift down a gear once clutch is hot and.......!!! bent forks again!!
    I have just recently installed a cheap chinese hydraulic clutch which has worked flawlessly to this point and are self adjusting...
    have only put a couple of hours on engine with hydro clutch and never had to adjust it as it gets hot, but time will tell.
    problem is..., when you rippin it up you dont always notice that your clutch is hot and out of adjustment, you just slam the next gear anyway...haha
    not to you pull into the pits and try to come to a stop/pull clutch, and nothing happens other than doing a drive by......lol

    Ive had two 155z’s. One was perfect, and the other had shift issues. The shift fork would pop over the drum and get stuck on the right side instead of being either side, if that makes sence? (There’s a thread on here with pics somewhere) I got it fixed and it hasn’t done it since, but I’m not sure how he actually fixed it.

    My brother inlaw had heaps of issues with his but it was all operater error. He put a larger gear lever on it and when would jump in his boot be half sitting on his gear lever and he bent the shaft, now it gets stuck in gear and he has to hit it with a hammer to unjar the shaft. Lol

    That being said, I still rate them! They’re a good strong runner, the close ratio box feels good. I’ve been thrashing mine for years (well not lately) and its still going strong. Just about everything else on the bike has fallen apart or broken but the engine still strong.

    We'll I have 3 155z engines and now that you mention it cordogs have only had repeated issues with one of them. Had issues with it from day one, the other have been great so far and 1 has a v2 head.
    The one with issues is the oldest of the 3 so prob just the first batch before all the quirks were ironed out.....
    I still rate them aswell

    Have you thought about an Anima 150?

    Great motors and 4 valve. Will eat the z160.

    yeah man, wack a pe28 on the 150 and youll be in for a fright!! ahah
    good strong motor, i have found they will start pulling valves around the 70-100hr mark, but its just as easy to get a new set and away you go again for another 100 odd!!
    yeah gearboxes are susceptible to a false neutral every now and again,ive heard you can re shim them to eliminate this issue, but its not a big deal, just give it a rev and kick and away you again, ;P good motors, plenty of power, you can buy decent pistons from Europe and other fancy bits too!!
    Cheap bling is always the best type of bling!
