I got a Sprint Po-8 filter for mine but its a gen 2,
Its not an oiled filter-=--> its oiless which i MUCH prefer.

Dont know if they make them for gen 1,s?
I did notice a big diff in performance from the
oem style paper one though.

Didnt mod airbox, dont need to.
Not a big fan of K&N.

Just personal preference.
good luck.

Email some performance shops.
What do the track guys use?

Pushing the stock air filter box down onto carbs can be a bit fiddly maybe due to the rubber seal hardening, I spray mine with a bit of WD40 or similar and then do the back seal first, running round the edge with thumbnail, front one is easier, but you must check maybe with a torch that the seal has popped out all the way round otherwise it will loosen. There is a bit of a technique to it, but it''s not like you have to remove it very often.

 

The gen 2,s can be fiddly also and easy to misalign the
rubbers and have a lip or poor
seal,
so i take the lid off and put the bottom half on firsti
i also smear a dab of synth grease around edge of
rubbers to help it slip on and seal good.

Synth grease doesnt hurt rubber.
I use a bit round the lid seal too.

That Blue Simota filter looks like a good quality
one for the gen 1,s.

 

I've never had any trouble with the stock Air-Filter knocking anything out ?

As for fitting once you know the technique it's easy,


Fit the Front carefully onto the seal first and then pull on the back of the Air-box towards the front of the bike from the bars making sure neither of the seals gets malformed! A thin smear of oil on the seals can help them slide on easily.

 

many thanx all, was thinking more of the pods, but seems everyone thinks to stay away from them.
Will try these ways of me=aking the box fit and stay fitted, Njoy

 

That's the best option. The Constant Velocity Carb system is a semi-sealed system that has been designed to work in concert with the Air-box. If you change any part of it you can introduce changes that will most likely lose performance rather than enhance it.

This of course is different if you are an experienced ,"Track Rider" who has access to modification experience and knowledge and don't mind spending time and money
