@buck : nice mod, did u get the head package ? remember exhaust port cant be bigger than 80% of total exhaust valve area, enlarging the port would move the power band to higher rpm, the problem is aftermarket header pipe on my country rarely goes that big, and the hole must be inline with the header pipe hole, in effect maximum exhaust porting is limited to 0.5 mm, so i think u use that head for bikes with bigger header pipe like R125 or got a custom header pipe ? 
the reason why the admission must be modded is that CFM measurement sometimes fools us, we must keep balance between gas speed and volume.

ok , i understand .
for me the exhaust is very big . Is possible to connect a leovince or Devil to the head .
a question : on the head is a hole in the exhaust side . on my head i don't have this . So i must closed it with a screw .
Why is this hole here ? for what need gaz from exhaust direct on the head ? this is very bad for oil and for the camshaft .
yes this is your head from package . only is missing a part but i can take from my Original head . this part come under the spring , i forget the name .

@buck : the hole near the exhaust side is the AIS (Air Induction System), your head didnt have this because u already got injection fuel system, the AIS could be disabled just by closing the hole using some kind of metal paste or epoxy, it wont harm ur engine coz it only supply fresh air to exhaust port so it can reduce emission.
@lincx : the 22/19 got same stem length and diameter with stock bro, heheheh... also it's non magnetic
.. pm sent

On the r125 is AIS directly on the exhaust :
And tuner exhaust are without ais .

of the cylinder head package.
tnx bro haen.
Cryo processed conrod bearing to increase its anti wear and tensile strength..
left side stock right side cryo processed.. not every cryo processed part had color change, piston, block, pin, cam changes how it sounds when ticked.. thicker sound.. signs of more solid part..
Usually cryo processed item got 2-3 times life time from stock
WHAT IS CRYO TREATMENT ?
