Fingers crossed then! Did u get it off eBay? It's coming from Greece I believe...Ordered mine Thursday and it arrived Saturday
morning TT great service
Have filter on order for fitting at 1st service! Is extra bhp from filter or exhaust?
managed to get mine here , DNA AIR FILTER YAMAHA MT-09 2013-14 | Motorcycle Exhausts | Performance PartsFingers crossed then! Did u get it off eBay? It's coming from Greece I believe...
Hi TT Yes ordered from Ebay, Yes it did come from Greece and i was surprised how quick it cameFingers crossed then! Did u get it off eBay? It's coming from Greece I believe...
Cool. Fingers crossed it arrives before dyno day then lolHi TT Yes ordered from Ebay, Yes it did come from Greece and i was surprised how quick it came
I was under the impression that a free flowing exhaust creates less pressure in the cylinder which allows the burned up gases to escape quicker which in turn means that its sucking more fresh air and fuel in which means the mixture is different than it was intended from the factory (as they allow for some unburned gasses to still be in there), which makes it run lean and to put this right you need to adjust the fuelling to compensate via an ECU map or fuel controller etc.I dont't know what to believe. My dealer told me in no uncertain terms to run my Akra without the baffle in would need the ECU flashed. Let alone with a filter too.
I know I'm running my Akra with the DB killer removed and the bike "feels" fine. I do have a bit of lurching while holding a constant throttle but I get that with the DB killer in also so I don't think thats related (hopefully my fuel controller will smooth that out) Only a dyno or A/F gauge will show how the mixture is really running. From the average Joe's point of view I don't think running an open pipe or filter will do any harm.I don't know about the technicalities but my engine seems fine, performance is excellent and have much smoother throttle control...no unusual sounds or blips....I'm happy!
Yeah it is confusing, by logic the only way the filter would cure the jerk would be because its restricting airflow making the mixture rich! But I don't believe an aftermarket filter would restrict air flow.Confusing isn't it?
I emailed the UK supplier BR Tuning (link in a post above)
Thanks for your enquiry.
We would recommend you get the fuelling checked after installing the filter but judging by the number we sell and not had 1 single adverse comment, I doubt there will be an issue.
We have recently sold some to a Yamaha main dealer who claimed they the improved the overall running noticeably.
So a dealer is saying the bike runs better with one - The mystery deepens.
All I want to see is a dyno report saying its ok with a std exhaust and I'm getting one!
If it works then roll with it, thats what its all about at the end of the day.The air filter INCREASES the air flow by 29%. Just wandering if its diluting the fuel with air slightly but enough to soften the throttle...off to Scotland tomorrow for a good lengthy run but have already blasted about on all modes with the air filter so expecting nothing more than its recent run of improved performance.....anyway, I didn't want to get into all this due to not having the aquired level of knowledge to give a thorough opinion....over to you chaps. Will enjoy reading your results and findings. Good luck!
How can it be BS if several people in this thread have tried it and have had it work? The only logical explanation I can come up with is that somehow pairing up an open pipe and a free flowing filter has got the mixture right.Dna it sounds like you are behind this. It is just to clear. If you want your product to sell also sell ecu updates this whole thread is just bullocks. Sorry to bust your balls sales person but leaning out even more is just complete bs.
