I think some of you guys may be looking at this the wrong way. The company is not trying to use the preorder folks to "prove" their technology. The carb design is already proven through the billet design. They have competed in the most grueling races, customers have them on their quads and bikes. All that is going on now is that they are making a more affordable design by casting.
On another note, I don't get why so many people are so up in arms or against the "preordering" program of this carb. A multitude of companies including Amazon and almost every major retail market that sells movies, video games, gaming consoles, cell phone, tablets, books, and etc. uses this format. Millions of people pre-order the newest Grand Theft Auto or the newest Call of Duty game and no one blinks an eye to it. But someone sets up a pre-order for an atv part and that makes the company unreliable? If I'm not mistaken, you have to "pre-order" any aftermarket chassis and pay for it far before you get it or see it in person. So I don't see the big deal in pre-ordering a carb. It allows a company to gauge it's first initial demand and act accordingly. It also allows customers to get theirs before the masses do, again just like video games.
That's the way most industries are done these days. It keeps them from having too much cash flow held up in the form of inventory. And as anyone who has been in the manufacturing industry knows, small batch of billet parts are the most costly, casting is cheaper, and die casting quite a bit cheaper but requires alot of volume. They don't quite have the volume demand for die casting yet, so they went with the next best option.
While I am a little disappointed that they have had to push their delivery date back, I haven't seen or heard a decision made that would make me doubt the decision I made to preorder a carb, or I would get my money refunded. I know how it is when venders do not get you parts on time or deliver on promises made. While I write this comment, I am also writing an email to a company vender asking them why they haven't sent me a report they promised to get to me yesterday. I only say that to say this, everything that happens is not always in 1 company's control, therefore, delays happen.
