airbox lid

[blasteracer24]

i have a blaster that is piped and is jetted for a pipe and filter. if i take the lid off will i have to re jet it or with the way its jetted now work?

[hardkoratvmxr]

in my opinion blasters should run with air box lid on all the time no matter what

[blasteracer24]

why do you say that?

[hardkoratvmxr]

because it is not reccommended to run a blaster with air box lid off

[chazekxt]

i runn mine with no lid

[blasteracer24]

what is it jetted for?

[bradley300]

you'll have to rejet for sure, you will have a good power increase tho. just make sure you have a good air filter(uni or white brothers) and clean it constantly!

[blasteracer24]

i have a uni so the way its jetted now wont be good?

[bradley300]

correct. you will have to go up at least two or 3 sizes on the main jet, and maybe even 1 down on the needle.

dont worry, if you dont have much money re-jetting is cheap (2 or 3 bucks for a main jet) and rejetting the needle is free. if you dont know how to jet, just say so and i'll write up a step by step. its real easy if you just get in there and do it

[badass250r]

any filter will work uni and the other foam just are less maintaince

i clean my k&n and outherware after every ride and u deff gonna have to rejet

there is a million tutorials online that show u how to jet and help u to understand it... if u really dont wanna take on the task have a local shop do it for u its cheap and if u want to take the lid off i would sugest getting a pro flow intake adaptor just to make shure u always have a solid seal so nuthin gets past the filter and always have a outerwear on the K&N

I think you should just keep the air box on it will keep more dirt out.

[blasteracer24]

if i drill holes in the lid will i have to re jett it?

[300exrider05]

no you will not because its not totally open.good idea though.just make sure your air filter is oiled so it doesnt let dirt in.

actually u will i had too and i put about 35 holes in the lid so i had to re jet cause it was getting alot more air

You can buy a lid with multiple holes in it with a screen overlaying the top of it. Then just utilize a K&N and rejet. YOu will notice a significant power gain. But please do not just run with the lid totally off, it's not recommended.
