    Yep that what i tought just thought getting Z155 or YX160 or Detroit 170.Z155 has cool revlimiter though :) Detroit seems just little betterer because more torque but still debating between yx160 or z155.Also is there available Fake Z155 or yx engines? One shop sells them for 635 and one for 550.Detroit is 600euros

    z155 has no rev limiter, thats valve float and bad for the engine!!
    All these china engines ARE copies of Jap engines,Those price differences could be for just engine or engine including loom,manifold,kickstart,gearlever etc etc...

    Just people say that it has rev limiter just before valve bounce on the new z3 160 and m2r 160 bikes.I could by the Z155 or yx160 too just unsure which one is betterer and im Sh*t choosing these kinds of things with no info at all which one is better.I know how to maintenance it and all that stuff tho.

    maybe the new z155 does have limiter, they older ones just needed stiffer valve springs.
    never had a yx160, but love both my z155's, one is stock and other has v2head.
    Easy to find parts for both engines, from what ive heard over the years the yx revs a little more than the Z, but the Z
    has more torque.
    I say get the Z155.....haha

    Pretty sure these Detroit 170’s are a KAYO 170 basically a copy of a yx160 just with a different head
    there not as popular as yx160 or z155 probly coz there not made as good Who knows
    There are other 170’s that are basically yx150’s with a big bore kits

    Your 100% better off goin either a yx160 or z155 they are powerful engines and proven to last and both have great aftermarket upgrades

    Just searched that KAYO 170 and the 170 isnt my choice anymore.Just seems like more cheaper made than YX160/Z155HO.Also in finland or in europe i didnt find ANY pistons or parts for the 170 so doesnt sound good.I have good suplly of parts for YX160/Z155Ho.In 160 just worried about the kickback if i crack the cases and about the seller.The Z155ho just looks way beefier but the 160 would be nice with upgrade capabilities.For me the CWBikes yx160 looks sketchy not sure why? Might be bad photo or something.ill attach the link below.Now about the oil,i found shop close to me and he sells Castrol and valvoline oils? He sells like Castrol GPS 4T 10w-40 and also Valvoline synpower for bikes and durablend 10w-40s.Now for the links
    YX160:https://cwbikes.co.uk/store/#!/YX160cc-engine-package/p/75820809/category=21641595
    Z155HO:https://www.pitbikeparts.co.uk/zongshen-z155-engine-carb-loom-18bhp-p-1636.html
    and no worries i will buy oil cooler with these and magnetic sump plug.Might buy one of those metal oil filters what i could just clean using petrol or diesel or with just airgun.Sorry for grammar errors im not native speaker of english :)

    You don’t need to worry about the cases dude go with he one that’s cheaper for you and easier for you to Get
    both those sites are pretty good pitbikes are real big in the uk I’ve seen a lot of people with cw bikes and welsh pitbikes so your better off goin thru either one of them

    The price difference is only about 20-30£ so not much.The cw would just be easier because i dont need to message the seller and wait for response the cwbikes website has UPS delivery and all of the text is in finnish and it calculates the shipping price automaticly so maybe that. im just comparing the Power/Durability ratio here and thanks for answer!

    Nice dude congrats


    Straight away drop the oil that’s in it clean the oil filter and replace the spark plug
    You wanna put 750ml be sure to check your valve clearance
    Everyone has slightly different way to break in a new engine
    I always break mine in hard
    Basically let it warm up for about 15-20minutes then go for a big ride basically go thru the gears But don’t let it rev out then drop the oil and clean you oil filter again and Have another look at your valve clearance you’ll see some metal fillings don’t panic that completely normal put
    Some fresh oil in and your good then just maintain it every service

    I couldnt sleep at nights because i was thinking between yx160 and z155 lol.
    The engine should be in finland next week :)
    I will adjust the valves with feeler gauges.I will just use conventional or semisynthetic for running in because i dont want to put too expensive oil when i know i am going to change it soon.
