    I couldn't see the picture well.

    You can run a filter mounted right on the carb.

    I thought about doing that on my Big Red, but decided to keep the air filter box instead.

    if your riding in only dry conditions I dont see why not, but once the filter gets wet the engine will start running like crap..

    I see it all the time where people run the filter direct to the carb. If your getting that much water the filter is saturated then you should probably be running a complete, nicly sealed airbox.

    The rubber boot will not prevent water getting in the carb, only the airbox would. If your running a K&N, and it is sandy around you, then you might want to buy an "outerwear" cover. They keep the sand out of the K&N filter. There shouldn't be any appreciable performance gains by removing the rubber boot, you've already removed the restrictions of the airbox. I hope you've thought about rejetting though. All that extra air will mean that you will need a little more fuel.

    Doesn't that boot have something to do with "smoothing out" the airflow into the carb? Maybe just on the intake to the engine, but I think that boot does more than just connect the carb to the filter. I'm sure it would run just fine, but those Honda engineers surely had something in mind when they designed it. Correct me if I'm wrong, which I certainly may be....

    No tim -you arent wrong---It was designed to minimize turbulence in the air intake, but only as a complete assembly --airbox included. Once you tamper with any part of the setup--its design purpose is gone----

    The first thing I ever do to Every machine I have ever owned is take the airbox off and install a K&N filter and outerwears right off the carb.I play in snow,mud,sand,dirt,rain and I have very minimal problems.If you fly through a 10" pool of water and really soak the filter.It probably will bog out.I try not to take my machines swimming or drown them in mud.But the regular stuff the tires throw up wont bother it.Just make sure you use a pre-filter or the Outerwears.Same thing just different names.

    It can--

    Less restriction = More airflow
    More airflow = Leaner Mixture
    Lean mixture = more heat

    The heat build up in the cylinder causes higher Cumbustion temps and can actually MELT -internal parts
