Hello guys!I have a 2001 sv 650s and i am very happy with this bike.I saw that later 2007 they put new cylender head with dual sparks.Do you know if i can put them in my k1 so i can twin spark?

you dont want to. because they make less power than single spark heads.
but you could throw the heads on and do dual plug coils $$$ down the drain though

My car has twin spark and i know that it helps with efficiency of fuel,so i want to do it for less fuel,no for more power.So i can do it?Thank you!

it's only for emissions. doesn't save gas.

also, the hundreds of dollars you'll spend on swapping heads and coils will take you years to offset with any fuel savings. if you want to burn less gas, go a little lighter on the throttle and keep the speeds down. or work on aerodynamics.

but yes, you can put twin spark heads onto a 1g. you'd need twin spark coilpacks as well. or just a second set of coils and daisychain them

Mad8vskillz is right. Dual spark plugs are for emissions. Pretty much to make sure that all the fuel is combusting and no nasty hydrocarbons are going into the atmosphere
