Uh guys... RC Engineering knows more about injectors than anyone here... If they tell me my spray pattern is excellent.. I'm going to believe them. But.. if you don't want to do it.. then don't.
Simple fact... it works. I got 600cc's and that was my goal. RC Engineering says the spray pattern is Excellent.. and since the injector has been flowed... It's pretty obvious that there are no shavings in it. Not like it would be hard to clean it out yourself with some carb cleaner or something.
This isn't rocket science... and our engines are not super delicate pieces of machinery. The sooner people get that through their heads the better off the community will be in general. Time to try something new instead of just doing whatever the next company that comes out says is the way to do it.
