I'm pretty new to mopeds and I just need to know if my air filter is alright. I really didn't know what to look for but I think its the circular reddish-brown sponge-like thing. Currently it is very dry and kinda shrivled looking but i decided not to mess with it. So I put probably 500 miles on it with no problems until winter made me put it away until spring. Can you guys tell me if the filter is in alright condition or should i replace or service it in some way. Thanks for you help.
