Or one could simply use a drop in filter in the OE air cleaner, https://www.ural-zentrale.de/en/motors/ ... 50-cc-ural

Better or Worse than stock?

Well the carbs it had were $#!+ tbh, previous owner had an obsession with originality and that meant unreliability. So I don’t know if it’s better than a stock carb set up, but it’s a f*ckin’ load better than what I bought. Mine still need balancing but are certainly giving me more reliable starting, the filters shouldn’t make too much difference I would think.

Don't know about 650s, but most folks including myself have found separate pod filters to be a headache to tune, and significantly compromise low end and mid range on 750s.

If that turns out to be the case I’ll have to rethink, but that plastic tub of string will not be going back on the bike.

Just to clarify, it's when pods are attached to directly to the carb that seems to be the most problematic. If larger pods are mounted at the end of a branch pipe that provides post filter volume such as this setup, http://www.modtopperformance.com/Perfor ... sembly.htm they work fairly well. If the separate pods are replaced with a single filter attached to both cylinders, https://www.speedwaymotors.com/K-N-MG-0 ... 00907.html then one is getting close to ideal.
Another thing to consider, the UK having a similar climate to the Pacific Northwest, exposed air filters are quickly overwhelmed in wet conditions.

Here's a simple, effective, inexpensive DIY that works very well. http://www.sovietsteeds.com/forums/view ... tka+filter
Thanks for the info, I’m assuming that a plenum is needed to take out the pulsing or something?
I will see how things go with this setup and if I have problems I’ll maybe put some extended pipe on there to move the filters back under the seat.
Climate problems noted, but if it’s that wet I’ll be at home!

Trouble with that is you still have the butt ugly air box, which is what I wanted to lose.

Pod filters have a clean look but
Not for every day weather riding.
You will never dial in your carbs correctly at all ranges with pod filters, your bike your taste. Look vs performance

Have to agree - I have used the big oval K&N's on my Guzzis, much bigger surface area and were quite well shielded being up under the tank and seat and between the side panels. Seemed to work well, however they do deteriorate eventually so no, they don't actually last forever. The cotton gauze acquired gaping great holes after some years.

PS: a friend who's got a 2012 Dalesman has pod filters on, but he told me about when he was stranded at side of the road in France due to torrential rain. He wanted to get rid of the stock oval "biscuit tin" filter box because it was "fugly". Image

Pods are fine for racing or running at WOT or just look cool. Not so nice to tune for low and mid range use working your way up through the gears. These clunky old tech dual carb motors like drawing air from a common plenum.

I had my 750 dyno tuned with k and n pod filters, very pleased with the performance. The bike was missing the stock airbox when I bought it so I dont miss what I've never experienced

I was thinking of something like this to maybe move the filters under the seat, should it be needed.

It's a possibility that they might be more suitable, or less of a compromise for a solo as its less burdened by weight and barn door aerodynamics, but that's just speculation, and subjective as to how and where one rides.

Here's my MG-size K&N with a cozy foam overcoat.
Don't use use the foam at present but it's ready for the inevitable shedding.

Whatever happened to that section set aside just for oil threads? Sometimes I feel like we need a section like that for air filter threads.

Back to the original topic (Retro looking mods), check out this old thread. It's got a nice article on a great looking Steampunk Ural:

Here’s the latest work. Copper plate changed for brass, and K&N style crankcase breather. I have also fitted new carb flanges as the old ones were split, a proper bottle screw on the front brake (from Germany- Ural zentral) New mirrors and handlebar clamps. Bike now starting second kick with new carbs etc. Still need to sort carb balancing but that will be soon.
