!00 If RK TECH believes like you both of you don't know shit about a 2-stroke engine!!!! Or a 4-stroke either!!! If you lower the exhaust port you would have to take some meterial off the bottom of the cyl. then you would raise the compression,and throw the port timings off to the point the engine w...
