  • awesome thank you.

  • I am looking for diagrams on how to install cams of an Audi A4 2L 2001 South African model.Its a doudle overhead.Iam struggeling with it's timing.

  • my kymco super 9 will beat this.

    98cc liquid cooler, upgraded everything. It does 76 (:

  • I thought GY6 is an engine of kymco :O

  • @mrtubeo sure, cause Honda don't make it anymore. It is so so so old......

  • @sergio7382 do you think is it as riliable as Honda engines? Im thinking about buying one, but I can choose smth else, like Gilera engine etc.

  • I'm sure it won't run !! lol

  • is that a whole motor or you cut it in half?

  • Lol...I have been building gy6 engines for 5 years and I"m surprised MRP let a few very important steps get missed... Oh and the head bolts should be torqued to 20lbs.. Chain tensionor is spring loaded and needs to be recoiled and held in that position until the mounting screws are snug..release the recoil and it set's its self... Valves should be set @ 4 / 5 thousandths intake /exhaust respectively.

  • @brokerover head bolts 11 NM, inlet valve and outlet valve 0.10 mm for GY6, and indeed the tensioner must be screwed on first, than the middle bolt with the spring automatically adjust the tensioner with the spring, the guy in the video is doing wrong lol. More engine secrets to make the GY6 go faster, but I won't tell that lol. I have my own scootershop here in the netherlands.

  • @barthoedemaker pretty good advice.

  • @MartinRacingPerf I'll give you another hint: the stock rear pulley spring is to hard for the 50cc engine to pull through, I always replace is with a 35% less stiffer one, better acceleration and a bit more top speed.

  • Comment removed

  • i want to buy a 150cc gy6 engine how much? how to purchase im from the phils.

  • just watch the spanish version is more helpfull( that guy doesnt use a torque wrench either but atleast he knows what he is doing.)

  • torque wrenches work good hand tightening hose cam cap nuts like that = snap!

  • pero cuales soerian los requerimentos dela moto y para que se ajustan los tornilos??, dice que pierde comprecion(eso entendi) bueno, que tan apretados tienenque estar??

  • no entiendo di pito alguien me lo podria traducir?????????''

  • @xXxCoMaNdoDxXx Lo primero que dice es que debes apretar el conjunto de los balancines primero una tuerca arriba y luego la otra abajo pero en diagonal, despues habla del tensionador de la cadena de distribucion el cual tiene un tornillo ajustable para tensar la cadena segun los requerimientos del motor.

  • Thank you so much i could not find the timing mark on my Baja dune i150cc go kart and this helped allot thanks again! :-)

  • This doesnt actually tell you anything...

  • It's spelt "Timing", not Timming LOL!

  • I KNOW... THIS GUY doesnt know what a torque wrench is.... may be im just a technician.... or hondas dont care about clearances and tight specs

  • You need to take it to a store have a mechanic check it out.

  • Hi my scooter was working then i changed my piston and piston rings and then put every thing and after this its wont start.could you help me please.its 125 gy6 its looks exacly same like yours

  • Shoot who ever edited the sound on this.

  • i am getting a sunl scoot and i am planning to get some performance parts for it but does sunl even use the gy6 engine in it

  • yes it will do more than likely
