Wow. It's crazy how difficult it is to get a straight answer on this K&N filter issue. They claim the larger one is the current production but anyone that orders a K&N Filter gets the smaller version. I remember posting a picture of my large mouth K&N filter almost 2 years ago now on the old 5th/6th gen header thread. K&N doesn't seem to have their shit together

I went by process of elimination. Tried the easy "diy" steps first before getting the discs checked at a friends shop. You're lucky the bobbin clean cured your issue.

When I had my Vtec it had a bad vibration under braking. I tried cleaning the bobbins but it didn't help. (I thought it might have made it worse) Took it to a shop and the discs were warped badly. I had to put new rotors on to fix it.

My Givi side racks aren't clearing my highmount pipe. Not a huge surprise as I have read the threads on here and elsewhere and thought it might be a problem, but my TwoBros can is small in diameter so I was hoping it wouldn't be that big a deal. So I added some washers and a longer bolt to one of the supports and I have tweaked the exhaust mount a bit to try and move it inwards. So far I have managed to get the rack ever so slightly away from the can, but with long rides I'm sure it will touch and rub a bit. I'm not worried about heat as much as I am worried about vibration and rubbing. What else can anyone suggest I do to get extra clearance? ...or maybe add something to the Givi rack to help with the inevitable rubbing? Thick tape maybe? You can see washers in this pic easier. That bar ain't bent. Well it is but it comes that way to clear the plate.

There might be an H infront of the A I'll have to double check next time I take the tank off.

That's the same part number on this filter. You can see it at the top right of the image. Above the K&N logo and beside the "MADE IN THE USA" writing.

I have one of those larger surface area K&N's. I read on the forums all about how the K&N was a lousy filter with a small surface area. Knowing the PO installed a K&N I went and ordered a Pipercross. When I lifted the tank to take a gander I saw this: Not the tiny surface area K&N I was expecting. The pipercross sits on the shelf. I was gonna install it but now after seeing your dyno.....hmmmmm

Nice work! Keep it up.

Wow! Great work Seb. Gorgeous bike. So awesome it got me outta retirement

looking forward to seeing more

That is totally TITS!

Good question. I also wonder how the oil pressure is effected by having an oil cooler with larger diameter piping. Anyone do a mod like this on a 4th gen?
