I suggest you buy and read graham bells two stroke performance handbook before you spout off about porting having no effect. These jugs are extremely restricted from the factory. http://ebookbrowse.com/gdoc.php?id=2...19058fe6aaaa31

I let I guy try mine out, but, I knew where to find him and he let me hold his car keys.

I watched a 40+- year old guy become a kid instantly.

So, if someone asks to try your bike, ask if you can borrow their car!

$30 for a cheap spark plug, porting does nothing, and apparently expansion chambers don't work. Oh and be sure to use the cheapest oil so your wrist pin bearing flies apart! I guess kids these days learn so fast that they become an engine tuning expert by slapping a cheap engine on a bike and calling it a day.

TAKE A SCRATCH AWL, OR A NAIL (DAMN CAPS LOCK) Stick it into yout intake port and trace out the upper part of the port onto your skirt.
Try the motorbicycling.com google custom search, this info is there in more detail.
