Improving a piston: porting, polishing...

[oldbiker]

To me that piston looks awfully weak, please let us all know how it lasts. I`m sure it`s going into a motor that has been well worked and puts out a lot of power so I REALY would like to know.

There is a very fine line between "hobby" and "mental illness"....

whats the point in weighing main jets....
its the flow rate that counts.

next you,ll be weighing bulbs to compare with wattage

There is absolutely no point whatseoever in weigthing main jets I fully agree, I just wanted to check if the scale whould measure the difference.

But..... who can tell the exact performance improvement provided by a larger jet;

- of course the engine runs better (if it was too lean previously)
- you shaved 0.03 gramms of you scooter (every little bit counts).

Ok on something weighting 90,000 grams + 70-ish rider (sorry I am a metric boy), 0.03 gramms is not that much, even F1 engineers would not bother... I must be really sick then

Nice idea though, if I can find different wattage bulbs I will weight them and let you know how heavier is a 5 watts tungsten filament against a 10 watts....

Now, where are my pills..?
