airbox mods

[trailripper1500]

are there any mods that you can do to a stock airbox, excluding lid mods w/out rejetting? if there aren't, what can be done along w/ rejetting? no holes or anything, like maybe cutting a section out or something. i'll look at mine tomorrow sometime and report back if i find something out.

why dont you just take the lid off? most people do. you could also buy a OutterWears air box cover lid that velcros on. there is another company that sells one that screws on just like you stock air box, but it has an OutterWears pre-filter insted of the plastic cover. you can get a CFM alluminum arm box for about !120.00 shipped off ebay.

i was riding in water/mud with my stock airbox (with stock intake tube) and the tube and airbox got mud and water in it, causing my carb slide to be scored/scrathed due to the mud inside it. if i drilled holes wouldnt this get worse???

 

[trailripper1500]

yeah, it would defintately get worse. i don't think i'm gonna want to spend that much money on an airbox. i think i might just get a plastic/rubber pipe and put it directly from the carb to the air filter, but just get a different kind of filter. that's pretty much what they do with the aluminum box.

ya you could do that, i would just leave it stock if you are really worried about getting mud and water into it.

i actually found something worth doing. i took off the stock boot, used the metal gasket and cut out a plastic piece in the same shape. i cut the carb end off the boot and attached it to pvc pipe. then, i put a 45 degree elbow and then added a pice like 2-3 inches long and put another 45 elbow and it goes into the box. i used one of my old cylinder airfliters from my other quad and all set. i just have to go out and buy plumbers glue and buy real 45 elbows. it is the same structure as the cfm airbox for a lot less money.

post some pics sound interesting

 

[djack12]

lets see pictures, or maybe a DIY.

if you look at a pic of a CFM air box, it is the same type of routing as that. and, if you want, you could potentially use up to like 3.5 to 4 inch pipe. the wider the pipe from the carb to the filter, the more air flow. i just need to pick up some real elbows and maybe wider pipe and i'll do a DIY. just wondering if i'll have to rejet. i'm gonna put the lid w/ small holes back on though.

If you're looking to custom mod your airbox, take a look at this...

I've never had a problem and with mud, dirt, water or dust... just don't drown it and you'll be fine. I also run a K&N as a filter.

[trailripper1500]

i'm gonna buy the stuff today. i'm gonna use 2.5 inch pipe and matching elbows that are 45 degrees. i'll try to make a pic and post it to show you guys what i mean.
