Tune Up
I recently purchased my 2005 GZ 250. As I do not know if the previous owner kept the maintenance schedule I want to change the oil, oil filter, spark plug, and air filter. Is this going overboard? :??:

Re: Tune Up
When checking the air filter you have to look inside it. The air actually flows from the inside to the outside. The inside will tell you it's condition. Also you might want to add an inline gas filter between the tank and petcock to stop the crude that makes it past the intank fuel filter. They are cheap, easy to install and are normally clear plastic so you can monitor their condition. You may also want to check the valves before too long. If you can't do it yourself, I didn't, pay a shop to do it. It is only a one hour job after the engine is cooled down. A little TLC will keep your bike happy and you riding.

Re: Tune Up
HIFLO oil filter is a HF 136. Cheaper than Suzuki OEM.

Need to be careful with that as the engine design depends on a given restriction in the air input to keep the mixture right. If the restriction is less, it makes the mixture even leaner than it already is and the bike doesn't run well. For a demo of that effect, try to run it a short way without any filter at all.

We have discussed this air filter many times, I am the one who first introduced it to the site, and I ran them exclusively on the gz, there is no real restriction difference (that I could tell) to speak of with these filters. The only big difference in them is the mounting plate is metal and not plastic, and it doesn't have that down tube on the inside part of the filter that suzuki puts in theirs, it has a lot throatier sound to it on the intake side because of that, but other than that, the only difference I saw in them was in my wallet. [EDIT] [Disclaimer] I don't have the GZ anymore, and I can't recall if I had done the needle shim/ fuel mixture screw mod to it before I first tried this air filter or not, so that could be a variable you need to consider if you try this air filter.

Can't comment on the end plates ( "mounting" plate?) but I certainly don't remember seeing anything like a "tube" on the stock filter. Are you talking about air box mods........or is this just a "senior moment".......for one of us ??? [edit] Maybe you are talking about the deflector that the stock filter has on the inlet ??
