Hello Everyone! I started building 2 stroke motorized bikes this summer and am now moving up to a DF250RTA. GREEN!!! It is being shipped to MO this week. I don't think I will have any serious problems titling here in Missouri.

When I think about a few performance mods, this is what I gathered so far from the board:

-NGK Plug
-K&N air filter?
-Jet kit 88->100
-38T rear sprocket
-Performance CDI

Does the bike still come with the Zongshen engine? Has anyone upgraded to the big bore kit or tried a ZS350 or ZS400?
