Hy people...I am from Croatia...
I would like to now if I could fit Polini Evolution 70ccm to tjis crankshaft???
This crank has 10mm piston pin.

Tnx RIROX22
 
depends on what piston is fitted with that evo70 , polini evo cilinder can be fitted with either 10mm or 12mm piston ..

but on a evo 70 I advise you to use 12mm pistons , these are stronger
 
Tnx Melf

Then I think to buy Stage6 Racing or Hebo racing replica...
Are they 10mm pin????

I forgot to say thet I m driving Yamaha Aerox...

Tnx RIROX22
 
I know but I am so pure with this English that i dont knowe how to ask...lol

Uff.........Can I drive Evo 10mm on this crank???? Is this crank enough good for this Cylinder??? This is my question...hehehe
 
the crank should hold it with evo if you have a light setup , but with a yasuni c20 or other exhausts like that I can not tell you if the 10mm pin will hold this , ik know that 10mm pin sometimes break and/or the needlebearings break , a pin 12 will certainly hold it.

my advise to you is that if you want to ride with evo 70 then you can better replace the crankshaft with a 12mm pin type
 
If you are going to buy a NEW MHR crankshaft, better buy it for 12 m.m. pin.

Part No. for Malossi 12 m.m. is M538009
Part No. for Malossi 10 m.m. is M537891

Part No. for Polini 12 m.m is P2100010
Part No. for Polini 10 m.m is P2100006

Then I will looking fowart to Stage 6 Racing or Hebo Manston Replica...

Are these Cylinders have 10mm piston pin??? I cant find....

Please responde....

Stage6 racing cylinder is 10mm and 12mm pin. (2 types)

Hebo Manston replica is only 10mm pin.

If you will fit these cylinder , I would recommend 10mm pin crankshaft.

RMS racing crankshaft (10mm pin) is very cheap and good quality.

You can get RMS racing crankshaft and Stage 6 racing cylinder in 250 euros.
 

Tnx for info but I have Malossi MHR Crankshaft...
 
MHR Crankshaft is Okay! 10mm pin price of Stage 6 cylinder is around 170 euros. and Hebo manston replica is 190 euros.
