Pod Filter/Jet Kit Questions

[ChrisK]

Hey all, I've been trying to compile some information on updating my M900 to pods and rejetting the carbs. There's so much information out there I'd like to bring it here to have it in one place and clarify my questions.

Right now I'm running an open airbox with K&N standard filter, I believe stock jets, and Staintune exhaust.

I'm thinking of switching to K&N pods and a DynoJet Stage 2 jet kit. Here are links to the products I'm talking about:

My questions: Am I correct in thinking this will be a good upgrade from what I have? Does switching to pods over an open airbox with standard K&N make enough of a change to justify this? I am at least the third owner of the bike and don't know if the jets have been changed, is there a way to tell without pulling everything apart? Should I start with one or the other instead of both at the same time?

Things I know: battery box will have to be modified, carbs will have to be re-tuned after the jet change.

What am I missing, thank you very much for the help!

Try "pods vs open airbox" and "enlarged airbox" in the search.
If you are after a performance upgrade, pods in this case look cool but are a small downgrade.
With an open airbox, stock jetting would make the bike run badly. It may have a jet kit already, but it may or may not be tuned for the best performance.

An open airbox, K&N filter and stsge 2 kit is a worthwhile upgrade.

Okay, and there's no way of telling if the jet's have been changed other than just a guess? Even if I take the carbs apart would I be able to tell?

Yes for sure you can tell. There are tiny numbers on the jets. Aftermarket needles have a more severe taper and usually a number code. If the bike has an open airbox and is running real strong and smooth it would have a jet kit.
I would save your money and forget the pods.
If you are looking to spend money, get high comp pistons, Ignitech ignition unit, FCR41s, and suspension work. If you can only do one thing, raise the compression with high comp pistons and have the timing retarded 2-3 deg.
