Engine resemblence?

Hi, having troube with my bike (chinese import) and just want to know if anyone recognises it as a copy of another. Just need to know because i think its the rollers but rather than email someone in china or spend a considerable amount of time taking the old ones out and measuring them or what every (im a complete novice), just see if anyone might know.
Thanks

have a look on the interenet should be able to find out the size.

 

16x13

4.5g on stock motor revs nicely and is far better suited then the start setup, theyre heavier on the rollers for MPG reasons.

 

oh cool, great. i had a look on the internet and found out its a "152QMI" engine. Found somewhere that sell stock rollers but they dont state size or weight.
So ill go for some of them then. thanks

Beedspeed and donotlink Pedstop will have the rollers and other stuff as well.

 

would it be a bit ambitous for a complete novice to try and change the rollers?
Ill have the whole day but ive never had a cover of an engine before lol
Would i need a specail tools before even trying?
Thanks

will i need one of them?

 

Yep you need special tools to get the variator off. There are rller changing guides on YouTube, have a look at them to see if you think you can do it. Otherwise, get some help the first time.

Is that normal for there only to be 2 attachment for the wrench? How am i meant to know if there the right size

 

theyl b way too big for a variator , variator nuts are usually around 12mm , get one with a bigger choice of scokets :beer:

 

12mm dont know what nut you are looking at.

 

so 12mm's wrong then lol?

 

yes. not sure what yours is but definatly wont be 12mm

 

lol mayb , i remeba mine bein sumthin liek that , mayb im just mongin out , ignore me

 

A lot of the impact wrenches im lookin at say for taking car wheel nuts off. About that size would you think? or is it just too hard to say.

 

car nuts are 17,19 and 21

think mine is something like 19

so yours might be something like.

but tbh it should take any 1/2' sockets

 

Cool, cheers. You've been a big help

 

I found out that the stock ones that come with this engine is 18mm x 14mm, will 16x13 fit?

Plus the 18x14 i can only find weights at 13g and upwards. How would that affect the engine?

 

Is your bike a 50 or a 125?

4.5g ish for a 50
10-12g for a 125

 

sorry, assumed it was a 50!

125 rollers are as stated.
