I need opinions on changing the stock stacks to short stacks or mix them up.
I havent heard or read anyone doing this yet on the 05 1000.
is it really worth it? Also, does the same rules apply for the 05 1000 as it did with the 03/04 1000 where you can use 750 short stacks??
opinions please

shorter stacks = more top end simple as that... you should remap along with other mods to see any good gains, by itslef its really worthless to remap for a 1-2hp gain

lees performance has had no increase in power like previuos models with stack changes on the 05 1000. he said save your money because it was not beneficial.....

I guess the 750 stacks will not work anymore, since the K5 1000 has +2mm TB diameter.
