Metal likely worse for reasons mentioned above!

RZ responds very well to filters as Mark said! 

I would expect a slight increase in performance and gas consumption along with a lot of jetting work to get it right using pods!  Personally I use stock airbox unless I don't have one or trying to squeeze out a bit more power.  Pods look better and perform better plus are usually a lot cheaper than finding a stock airbox.  There must be an application out there that may be non-motorcycle you will have to source as I've seen pods on all sorts of motors...

Thank you. I'm having to order some small O rings on the throttle stop thingy....the supplier carries all types of jets etc, so thought to order a few to play with.....what increments would make sense?
Or, should I bite the bullet and order a Sigma jetting kit from the US?

Stock jet sizing:
Main - 82.5
Pilot - 20
Needle position - 4

I think raising or lowering the needle alters fuel intake, along with a rise in jet size would also enrichen the fuel....does this compensate for the pod filter? Plug colour will be the test...or a blown engine!! Haha.

Stripped the carbs and found the mains are 87.5,so does that mean they've been upgraded by 5.0?

In which case that might balance the pod filter with a richer position on the needle too, perhaps?

New to carb jetting etc. Any help appreciated.

One size prob wont do it, usually 3 or 4 will get close on a piston port. (assuming it sized in 2.5 incrememnts)  few more sizes for the chambers. you're just going to have to test.  this si from experiences with a GT250 and rd chambers. so, similar.

Ah, Ok thanx...never jetted up before so interested to hear your advice. Looks like I can get varying sizes, so a selection might work when it comes to it?

you'll probably need to rejet for the foam.
Do not underestimate the power of a two-stroke.
