I just recently rebuilt my engine and put 1mm oversized pistons in it. I also put new moto tasanarani v force reeds reeds in. It runs ok, but still bogs down a little while first taking off out of the water. I was reading up on how to adjust my mikuni carbs and not sure if I should jet the carbs or keep everything stock in them and just tune the carbs for the larger pistons. Everything is stock in the ski except the larger pistons and the v force reeds. Is it hard to get all 3 carbs dialed in exactly, or I'd this something that would be well worth th money to take in to the Yamaha dealer for them to tune it? Thanks
