not to be a dick, but i think you need to read up a little more on preformance mods before you try and give advice. advancing your timing more than 5 degrees isnt going to blow your motor, theres a reason you can advance and retard it 10 degrees. also, boost bottles dont do anything for performance. and chill on the exclamation marks!!!!!!!!! lol
technyne, like drewski suggested, do some searching/reading. theres loads of info on here that'll help you figure out what will work well with the type of riding you do.
to start you off, i would suggest buying an adjustable timing plate and running it at +4 degrees. depending on how deep your pockets are you can buy a cool head and throw in a set of smaller domes (the smaller you go the higher your compression will be and the higher octane fuel you will need to run) or you can just have your stock head milled. and as for the bog on bottem end, theres no need to buy a bigger carb, all you need to do is change your jetting.
oh and, welcome to BHQ!!
