You may have to suck it up and pay the piper. Do you want to ride or do you want to get so-frustrated, that you sell your bike? Even if you know what you're doing, you may need a helping hand in getting things tuned correctly. Doctors consult one-another, and there's no reason mechanics wouldn't.
Parts aren't cheap. You can have done everything correctly, but you didn't get the diaphragm aligned correctly, or you have trash in the tank, and your correctly-cleaned carbs just get the small orifices plugged again. As was said, you could spend $600 in parts if you had a lot of things wrong w/your carbs, but until you tear them down, you won't know what you have.
If you can't afford the work, maybe this isn't the bike for you. We all like to conserve our $, but if you cannot do the work correctly yourself, you need to pay, and better to pay someone who knows what they're doing, as-opposed to a mechanic who hasn't worked on a VMax in years. :confused2:
