What air filter?

Whats 3/4 throttle ?
What are all those numbers that go higher than 4 on the right hand clock ?

What ya do Si, is get it into 3rd like normal, then when you're about to change into 4th, instead of throttle off & go up a gear, just crack the throttle right open  (and hang on)  & watch the wee right hand needle go to where it likes it - 6's & 7's are it's favourite numbers . . .

So used to driving a diesel car all day I rarely go over 4k rpm on 14...

Over a year now since K&N fitted. Bike runs perfectly, as it did wit OEM. The smaller intake one i had from Klauss in Poland was ok, I dont go for power but can definately notice perfect revs from start to finish. Also better fuel mileage, never measured but notice a few more ks between fills. Im a big fan of dry paper, so OEM is perfect. Just having to wash out K&N also suits me. Thats a big change for me, always liked dry paper. Things can change.

You've got the slower R&B model so it doesn't concern you....

I need to find a seller of a real air filter though, I might even ask the local dealer. Robinson's have superseded their part number to one that includes 'K+N' so I rather suspect it's not OEM.

Yeah but add it to your basket & go to the checkout & you get this.

I've found them online for £24.50.

You can see it's a proper one as the trumpet doesn't extend inside the filter, every aftermarket one I've ever seen does.

Certainly looks OEM including the numbers. Good price. I pay 30 € for mine.

Would you measure the opening when you get it Hooli?  (and post here)

Might take to my aftermarket one with a dremmel cutoff disc & chop that internal piece out.  The blue has a K&N fitted.

@KiwiCol

Just to compare - K&N inlet is 56mm, versus OEM 48mm and Hiflo 39mm

I replace my Hiflo to Suzuki OEM.
Hiflo intake is 39mm, OEM intake is 48mm - it's area is 34% bigger than hiflo one. Also it's slightly higher - also easy to get air throw.

Local prices are ~25€ for Hiflo and 35€ for oem, so my choice from now on is Suzuki OEM.

Thx Andre, I knew it was on here somewhere, it was a quick visit to the site while at work when I asked the question.

And yet my bike runs just fine with the HiFlo air filter fitted..
Mind you I dont tend to screw my bike everywhere I go so maybe thats the difference.

With the Hi-Flo, I don't think it affects whether the bike runs fine or not, more that it can restrict performance having the smaller intake.

My bike has always run perfectly with 3 diff types of filter.. Cant remember thoughts/sound on stock paper. When K&N fitted i could notice diff sound even though its a long way from ears.compared to smaller intake/tube down inside type. No testing but also think fuel mileage is better and revs easier above 6k. No test or figures to back up but quite happy with it.
