I've seen a few people mention wanting to try different, perhaps more effective filtering material. Who's actually set something like this up?
I'm not really big on the idea of dust particles or any other small things getting into my engine's air supply. Hardly overkill. I've seen Brett say the material he uses is adequate for this, but I'm curious to see what other have done. Do you think those scotchbrite pads are fine enough for this? I saw one member mention using a thin oiled material of some sort.
i did not say unnecessary, just minimal again you mention longevity but where is any documemnted case of engine or valve wear on a 51 motor of any kind not just filtration? just sayingI disagree with the notion that filters are unnecessary. Every engine I have ever seen has a filter of some sort supplied from the factory. It is absolutely essential to the longevity of the engine. I doubt a metal screen over the stacks would provide enough filtration, and I'd be afraid silk screen material might get sucked into the engine, especially after it deteriorates over time. Not worth the risk to me.
I use Uni Filter bulk foam that's available in cut to fit sheets. The same stuff used for motocross filters. I use the black foam, which is 60 pores per inch. I just oil the filter media like normal, then I seal the gaps with No Toil filter sealing grease. 6000 miles and no problems. I inspect it regularly and clean it as needed with the Uni spray cleaner and re-oil it and I'm done.
The filter media is $15 I think and there's enough to make about 2 or 3 filters in the package.
I am concerned about mine after looking under the tank as well. I'm going to have to come up with a filter solution, prob work on it this thurs. There was a thin layer of fine dust covering pretty much everything inside the box. Not good.I got my RC51 with a TurnOne airbox and some bullshit mesh household screen on it and was doing a new bottom end at 33K miles. The inside of the box, bottom of the tank, TB's, everything was covered in dust. Yeah, we breathe the same air, but we don't have a thousandth's of an inch clearance in our lungs, either.
See my post with the pictures above.where is any documemnted case of engine or valve wear on a 51 motor of any kind not just filtration? just saying
I had 30 PSI compression in the front cylinder and 105 on the rear; a leak down showed massive losses through the intake valves and rings on both jugs.these bikes and motors are bullet proof nearly they don't wear out because of not enough air filtration
Link?FWIW the OEM air filters were bench flow tested with enough CFM's to run a big block chevy
