First of all, let me preface my question here..... I'm not out to get more power from my 2006 450F. If I did need more power, there are better ways of getting it than with a new air filter. Secondly, I do not believe the manufacturer's claim of gaining 5 hp. This does nothing for me but sets off my BS detector , & I can't use all the power I have now anyway, so that's a moot point to me....
But what I think I like is the way this filter seals up. I'll try to give a link to the Yamaha 450 setup here:
To me, this just looks like a much more positive seal, if it's executed right. I personally fabbed up a similar kinda deal for my old vintage mx bike, 4-5 years ago. Here's some pics:
I machined a round, double-sided flange that would allow a hose from the carburetor to the flange to be clamped cleanly & solid to one end of the flange. Here it was in the "fabbing up" process:
How it worked out:
The Uni filter has a round rubber seal with a hose clamp surface molded into it. A simple hose clamp held the filter tight to the flange I machined. Kinda similar to the Loudmouth's setup, them copyin' bastards.... (just kidding here... )
Anyway, I hate the price of this deal ($200!!! ). I'm not certain the items you receive are worth that knda money. That's one thing that'll probably have me simply buying 2 extra Twin-Air filters, and hoping the rim to airbox seal is good.....
But it would seem to me like it's easier to be visually certain the filter is 100% sealed with this setup. One thing I dearly liked about my old KTM300 was the design of the airbox. It's sorta similar to my 450's, but the filter was sorta turned almost 90 degrees sideways to the carb, making it easier to visually see that the filter was seated correctly. I can't tell this with the Yamaha, at least not visually.....
Does anyone have any experience with these setups? What are your thoughts, if no practical experience?
