I run a jack shaft and i was after more torque and i did not want to be like the guys that just remove the end cap/drill holes to gain more torque at the expense of noise because noise+streets=cops and cops=attention=strict new laws. I tried to make a write up and do pics. But way to lazy so I made a video that explains this near free mod.

That's cool, good idea. I'm brand new to this gasbike thing, made my first ride a day or two ago. Nice to see workable solutions I can draw from as I go. Thanks!
 
It's almost the same as a compression release. VERY creative. Opening the exhaust like that would probably help with starting in colder temps as well.
 
Careful that you dont lean your motor out to much running wide open with the cap open. Usually big air flow changes thru a 2 stroke require different jetting. I like the idea though.
 
At wot it runs better closed but I will watch the spark plug to make sure a lean coundition is not presant. Wow that cut out cost gave me sticker shock havent had that sinces i went new car shopping, but I knew it must have been done some where befor. ANd it does make it easier to start but i live in az so a "cold" start is rare for me. thanks for the info = )
 
Ok, I must be missing something. The video makes it look like your bike is left side pedal drive and right side engine drive. Did you invert the video somehow?
 
The video is backwards, i didnt notice,its off my web cam on the computer and i have no idea how to work it.
