The K&N is an AIR filter right? Not an oil filter; these were reported to fail/split. The ones witha nut on top. Hi Dutchy....yup its the air filter. Funny I have never used a K&N oil filter 🤔 Always use Wix oil filters, they have a better filter media, better valving and more media as well.

Ken Posted April 21, 2020 Author Share Posted April 21, 2020 Does anyone happen to have the Mosfet R/R part number to order as well as the replacement harness plug to the R/R? Link to comment Share on other sites More sharing options...

You want a Roadstercycle SH847 Kit. It comes with everything you need. It’s a Series R/R, which is the latest technology and considerably better than MOSFET. https://www.roadstercycle.com Link to comment Share on other sites More sharing options...

Hi Ken. Your air filter mod concerns me a bit! Haven't heard of others doing it, It's no doubt great for keeping your air filter clear of large particles, as well as stopping nesting vermin living in your airbox. But I have concerns about air flow, especially at high RPM's, given that the area of the wire relative to the air holes, guessing you could see a reduction in area nearing 50%!!. I found an online calculator and for a 750cc engine at 10,000rpm you're roughly drawing in 50litres of air every second! (See attached). Also the effect of any debris/insects caught on the snorkel screen will have a far greater effect at reducing air flow than the same stuff falling on the internal air filter, due to the internal air filters far greater surface area. I'm sure if Honda thought that a pre air filter filter was a good idea they would have installed one on the snorkel. In my experience the stuff that clogs up your air filter over time is mostly fine dust/dirt particles which would get through your screen anyway. It would be very interesting to see the effect of your snorkel filter on a Dyno chart especially in the high rpm zone. Be interested in hearing what others think of this mod. Just a thought. Cheers.

Clear and concise as usual Grum, sounds like a bad idea with good intentions to me. Air filters aren’t that expensive are they. Link to comment Share on other sites More sharing options...
Member Contributer MaxSwell Posted April 22, 2020 Member Contributer Share Posted April 22, 2020 I cannot remember why, but I do recall there were issues with the K&N air filters. One of my machines came with one when I bought it. I replaced it with Honda OEM. And yes, they are cheap for what they do to keep your engine running "long time".

Wow....have not thought if my model from that standpoint.Thankyou What I may do is give it a good run on the next warm day....self isolating as well😉 Then maybe directly after remove snorkel screen and try to note any discernable difference. To remove would be literally minutes so not a big deal Link to comment Share on other sites More sharing options...
