buzz..what your best option i think would be.would be not to de-tune or go to a larger back sprocket as l/b/sprocket would make it even more scarier down low(bottom end power),you can put a stopper(piece of nylon/plastic)block in your throttle tube housing to limit the revs you need,and as you get more used to the power,you can just shave 1mm at a time off it until your happy with what you can use(power)or conversly you can get a throttle tube housing already made for the kwakas on the smaller bikes that have a long threaded bolt with a locknut on it that you adjust to limit the amount of throttle there fore power that is required,,and as you get more confident(want more power)just crack the nut wind the bolt out 1/2 to a full turn out and that would allow more fuel/air in to give quicker acceleration/power..and i would not even go down the path of changing the volume of fuel/oil/air mixture of the combustion chamber(what 2 head gaskets)would do,as this could change other things and just complicate your problem..?..remember..better your sister in a brothel than your brother on a yamaha/honda/suzuki...go green bro and stick with it..and if your 5hunghy ends up killing you,.?.put this on your gravestone..I KNEW I SHOULD OF BET ON THEM 65 HORSES RATHER THAN RIDE THEM..hee hee hee..ride hard bro.. you only live once..madmick.(im not realy mad,i just get cranky sometimes).later.bro.
