GS Air filter
Had the lid of the airbox the other day and noticed the filter and box had light oil on them,is this normal for a standard filter or should it be dry?

The oil in the air box is coming from the crankcase vent line. If you can do a search for Lamonts catch can, or Baja Ron's in line filter, this is a way to stop the oil from reaching the air box. I've been using the catch can for the last five yrs. on my '08 GS, and it been working for me.

If your paper filter had oil on it you might want to swap it out. Oil on paper doesn't flow so well....

Or get JT's air intake kit like I did. Saves a bunch of room under the plastics and gets rid of the oil issue

If I was to replace the paper filter with a K&N would I need a fuel controller? I have a Hindle exhaust which I believe is ok to run without a controller fitted???

In North America, replacement paper filters for the GS are available at any local auto parts store. Depending on how close you are to your BRP dealer this may be easier source.

You will not need to run a fuel management system if you just change out the air filter with a K&N or similar. If you change out both the air filter (to a higher flowing version) and the exhaust (also to a higher flow model), then chances increase for needing a fuel management system.
But you need to get rid of that oil coated paper air filter right away. It is not good and will set up a vicious cycle. Oil on a paper filter will greatly restrict air flow increasing the negative pressure inside the air box which will suck more oil from the crank case vent which will put more oil on your air filter, etc.
Not sure what a K&N would cost over there. I carry them for $38 + shipping which would be $11.50.
One added advantage to a K&N type filter is, if you do get some oil on it, it doesn't hurt it at all. I would still take measures to stop the oil getting into your air box though.

Depends..!
some air filters are pre oiled like the K&N's. Oil will collect in the airbox over time from the crankcase. The standard paper ones do need changing from time to time. I ran a K&N filter in the stock box with a Hindle exhuast for a year with no problems. Recently replaced the stock box with JT's air filter kit and running a bit better and no problems.

I think K&N air filters come pre oiled, but don't know "specifically" the Spyder filter.

Same as the car filters....The stock Spyder paper filter will get trashed pretty quick with oil. The k&n it won't matter if it sees a bit of oil spray from time to time.
While its best to try to control the oil level to keep it out of the box, its not always possible and very difficult to monitor. This was another reason I ended up doing a k&n......

It is a definite maybe. It seems to vary from Spyder to Spyder. The fuel system does have some ability to adjust. You'll have to try it to know for sure.
Here is a link to my crank case vent system. It isn't a true catch can as you never have to empty it or service it. You put it in-line and pretty much forget it. I like it for cost, simplicity, lack of maintenance and it puts clean oil back where it belongs, in the crank case.
Oh! And it keeps oil out of your air cleaner too!

All K&N filters are preoiled. You don't have to recharge them.

Ok decided to have my first sesh in the garage with the Spyder and stripped out the air box.Wasnt too much oil in there and the filter was fine so just a clean up and re fit.Checked the missing plug while I was in there :L looked fine but will be upgrading plugs and cables when I service it after the summers past.Thanks again to BajaRon for his input also to the lad that made the videos in the DIY section made the job so much easier and enjoyable
