2 stroke porting....

[markybda]

Hello,
I have a few questions regarding porting a 2 stroke block.

Specifically I have an aircooled 100cc motor with an allminum block + cast iron cylinder.
The motor has reeds that are in the crank case and has 4 gears and a foot clutch. (v100e)

This motor is the very similar to a Yamaha V80 motor that we guys in bermuda put V90 cylinders on them bored out to 100cc's.

I have pics that I will post of a stock block and a ported block that is VERY NICE! I have ported blocks before but i would like tips as to know how much to change the port timing by changing the flow of the transfers in a 2 stroke motor.

The v80 motor is basically a yamaha PW80 with gears that are longer and change in the opposite direction.

The upload error is not you're fault its the server's fault.
If u upload a file it always makes a temporary file to save it temporarly.
And then it gets the users input on what the name should be.
And it renames the file and then save's it to a folder.
What it basicly is saying is:
Upload failed because i couldn't write the temporary file.
Try a different host.

1 thing i noticed is the link:
it ends with the current file name:

is the ':' also showing in the file name on ur pc? try removing it.
if not try a different host (imageshack, tinypic etc.)
