New 70cc cylinder for 101r.Opinions please!

[Joonas-t]

Hi guys,

I'm considering getting a 70cc cyl. to my scooter and ran into some questions:

Some of the 70cc kits on the market dont come with a cylinder head and it says You have to use the current one you allready have. Stock cyl. is 50cc..can i use the same head on the 70cc one or should i look for another one, that has a head in the kit?
Is the crankshaft of the morini engine going to hold up on this extra power? Some say, that Morini's crank is BS and will brake immediately?
What else should i bear in mind?
Can i have your opinions on that? Thanks in advance!
Here is one example of the cylinders i found on scooter-attack:

https://www.scooter-attack.com/shop/#!/en/TGB/101R-50/Cylinders/70cc-Sport/DRKT00057-Cylinder-DR-70cc-Evolution.html

The shop says on the drop down list selection, it should fit my scooter.

the 70 will give you more torque in the low end
but not raise the top speed much even if you put on a
un limited cdi  .
its the high rps ~over 10 or 11,000 , most stock cranks
are stressing the one saving grace about the morini is
that the main bearings are direct lubed which is better than
the minarelli that only gets vapor lubed.
