Default Keeping air filter dry?

I'm a noob so I'm gonna ask what is probably a dumb question. If I've removed the stock air box and put on a custom air filter. What do I do about keeping it dry when I hit water in a creek or it starts to rain?

Cool

I took a large clear windshield washer fluid plastic bottle , cut the top off , slid it up from the back , goes almost to carb , poked a few holes and zip tied to framework . Opening is facing forward ( Ram Air lol. ) Tons of room all around filter and large opening in front . Keeps wheel , chain / sprocket splash off filter .

Well so far I've taken the factory air box and remounted it in its stock location with both the sides cut out of it about the size of a softball and put the self made air filter in the box it seems to hesitate and bog down anytime I apply a third maybe half throttle

Outerwear or K&N filter socks do well.

K&N filter with an out wear cover is the best setup, but not cheap.

Also keep in mind that anytime you modify or replace you stock air box, that extra CFM of airflow needs a larger jet installed the carb to run properly, as well as get the full benefit of the extra airflow.

that's going to be way to big of a jet, for just a filter upgrade.

Even with the cdi ignition coil triple conductor plug? I thought it came with like a #90? But that was just what I found another guy using in a gy6 150 so I assumed they were all about the same but since I can't find anything about my buggy really and haven't seen anyone else modding one I don't really have much to go on except trial and error. Any help and advice would be greatly appreciated! Thanks in advance

Most likely a 120 or 125 main jet. Buy a three pack and get plug reads for the best indication.

Idk exactly what plug reads are exactly but I'm sure it's a way of testing which jet works best. I can Google the rest I'm guessing and figure out what to test with etc etc but I really appreciate the help everyone. Trial and error tends to get expensive with me lol. As I like to test, tear up, test again to make sure it was something I done that tore it up, tear it up again then move to the next test! Lmao. Mostly I just don't like bothering others with too many questions I know how busy life can be but I'm always open to any suggestions, pointers, rule of thumb ideas. If I get to a spot I have to ask I want hesitate to come here as y'all have already made me feel like it's Aite to have questions and it's awesome to step into a community of people knowing no one but still feel connected. That's rare and hard to come by these days. Thank y'all

I've seen a lot of home brewed air filter systems. Some work o-k, A lot don't. You can save yourself time and frustration by trashing the stock setup and simply using a UNI filter. Most all end up going to a uni as soon as they get weary of the tuning hassles of getting a home brew system to work. The uni is designed to give all the aspects your looking for, great performance, protection as good as it gets and durability It's a very easy /quick unit to install and simple to tune for. A uni only requires a wash and oil and it's good as new for several years.
Their cheap enough to keep several on hand. I'll clean and oil them up ready for use then store them in zip lock bags. Take a extra with you if your on the trails when there's the possibility of clogging one. takes about a minute to switch out then clean the dirty when you get home.

You should like the Uni filters.
Don't be super concerned about a bit of moisture getting in the intake tract as long as it's an occasional happening. It can actually help to clean the combustion chamber. The water turns to steam and loosens carbon deposit from the valves ,pistons and the head chamber. It will give a little steam clean happening. I'll periodically spray a mist in the carb while working the throttle to remove any possible build up of carbon. it will clean up the exhaust tact too. A old Drag racers trick was to rig a spray nozzle in the intake to give shots of water to help control detonation, enabling them to run more advance timings

Nice! I need to do something with the exhaust. I know the more air in the more you need out but I'm not trying to kick 300 on an exhaust right now. The stock muffler has a hole in the bottom from sitting on the rear axle.

Tighten a wide band clap over the muffler housing until you replace it with something else.

I love the HammerHead stainless steelexhaust, it is a bit "pricey", but what a great unit! I have "hand built" a couple of exhausts myself, and I've found that the old "silencer" type baffler/mufflers on rototillers seem to work really well, and they are easy to "tune in", but that's just one persons opinion! lol
