Hi ! VT500 all over the world !
J6G1Z:
Cylinder Head Porting, is the art of re-shaping/re-contouring the intake & exhaust ports to reduce any restrictions & increase flow.
To perform the job correctly, you need a flow bench so you can measure your results. An average mechanically inclined guy with a few tools can improve upon the stock port contours by simply cleaning up any casting slag & smoothing any angles that might be present. Remember to stay conservative in your efforts.
Porting is both an art & a science that you could spend a lifetime learning.

Only there is a theory and a practice!
When I plane cylinders, I confide the whole to a specialist. I do not make it myself.
I have a problem to indicate you reducing how much cylinders.
It because of our differences of measure.
On the VT5, we can content with tightening more hardly the breech or with abolishing the joint of embase. (The water is external)
This engine likes that! No problem of premature wear.
Joe D.:
I really like that windscreen on that model.

Do the French have some odd sort of measurement? I thought you were on the metric system, like most of the civilized world. ;D
Dibingo:
Ok ! :D
My cylinders are reduced of 0,6mm !
We can make more, but I prefer to keep of the margin. This modification really transforms the aggressiveness of this motorcycle ! Nice !
