What air filter?

[DP1400]

 :hat:grog, doh! I think there`s little point in re-iterating what i`ve already explained earlier in this thread, but for the avoidance of doubt, if I had been lucky enough to purchase a K7 from new, then likely as not it would still be running with standard Suzuki replacement service parts......

Have had my beast nearly a month now .  when I filled up with juice first time I put 95 in it which stopped all the popping ,spitting and farting !!!  (the bike not me !)....I'm guessing must have been filled with 91 before ?    So what do most people use ? petrol varies between countries etc  too . 

Anyway its going great  ( has the tri oval Yoshie on it which they did here in NZ for the last few apparently ?  Rego'd first here in 09 one of the last?).

@Roo Please head over to https://gsx1400owners.org/forum/index.php?topic=2701.0 to find answers to your question. This thread is here is about air filters.

Had a significant induction 'sucking' noise since I bought the bike. Not any more. Ordered a genuine filter for abut £37.

If anyone is interested what the pipe looks like on the non OEM filter:

Yup & even after removing that, the hole is still smaller. Plus the bike doesn't run as well as a genuine filter, at least mine doesn't. I assume it's because it's not a smoothed intake & restricts how well it breathes.

I guess that along with the intake hole size, the filter media might not be as free flowing in the third party filter.

[Hooli]

You could be right. I'm going on the extra noise, which is normally a sign of restricted flow.

Anytime I had pods on a bike, my Katana with CR carbs there was increased noise that wasn't because of restriction in flow.
My RD400 runs standard and has high induction noise, don't think it's from low flow. So I suppose it works both ways.

[Hooli]

True, but then you didn't have an airbox to hide the noise either so it would be louder.

I'm sure you know noise is vibration & the only way airflow will produce vibration is via turbulence, which will restrict flow.

I'm no expert on this though, I just know those aftermarket filters made my bike slow & thirsty. Taking the intake pipe out of them helped at low throttle/speeds but it still didn't run properly and it had a lot more induction noise in normal riding.

we need a turbo, that'll fix it

Pfft, only asthmatic engines need ventilators.

14 is badly asthmatic

Bought a Hi-Flo air filter a while ago. When l went to fit it l changed my mind and bought an OEM filter, which finished up being cheaper too

I still have the K&N in mine, and it hasn't been cleaned in over two years.

Irish, not allowed to mention them. Worm cans etc. You can guess what i use. 😎
