Running all bolt-ons with stock twins and Power FC. Should I upgrade the primary 550cc's to 850cc's or just upgrade the secondaries to 1200cc's ?? Thank you.

Will this be it for you? Are there plans for a single conversion down the line? Will you be happy at this power level or are you like me, happy for a little while, then you add more? If there are more upgrades in the future planned, I suggest you go with the largest injectors you think you will need for your final plans. No sense in settleing for what might get you by now and then have to buy more later on down the road.
