one word.. DONT!!!!..... yea it'll be fine for the few couple of times but eventually it'll kill the tranny.... and you know how much honda parts are.... crazy $$$ so dont bother.. you can use the money elsewhere....
as for double clutching... thats gay... stoopid fast and furious has all these dumb things in peoples minds now...

but if you really want to get a really good kick.. its kinda the same thing as double clutching.. but its really called power shifting... basically you keep your foot on the gas matching the RPM while pressing on the clutch to shift... i dunno... hard to explain.. i could show you but i doubt that'l happen....
