Question Filter w/o airbox to test engine?

I'm now looking for pods (without much luck) so that I can test O's engine without the hassle of installing the airbox yet one more time. Pep Boys has 2 5/8" pods, but I'd have to do a little work to get those to fit snugly to the carbs. Is there anything else I can do - like put the carb-to-airbox boots on and cinch the air filters to the end of the boots? - so that I can just see if the engine runs? I need the OEM setup for emissions inspection, but I'm a long way from that at the moment.

Any suggested shortcuts at this point would be greatly appreciated.

Thanks!

I'd just use the rubber boots that clamp on to the carbs and cover the other end with a well secured "toe" cut out of some cheap panty hose.
Stretch it over the opening and tire. wrap. clamp it down well so it does not get sucked into the engine. This should provide a good enough air filter for your use here.

Part of the problem alsois you just installed a "less restrictive airbox" so your jetting will end up being lean.
Hard to take a guess here, but I think if you cover half of the nylon with tape to close off some of the intaked air, you should be in the ball park of the stock system.

You can of course run the bike without any air filter on it,,,but I would not do it for more than a few minutes, and that is after making sure the area around the carb mouth is fairly clean.

Thanks - I was hoping I could do something like that. Definitely will lower my frustration level a bit.

Or purchase locally or via your favorite internet seller some filter socks- Uni is my favorite brand. Most people use them on dirt bikes, but the work fine for ours too. About $8 each.

I was reading through earlier posts where you had mentioned these, but I swear the fine folks at the local auto parts stores haven't one brain cell between them all. I ask for stuff (including the product you mentioned) and they just look at me blankly. "Blink. Blink blink." I explain the purpose of what I'm looking for, and that only confuses them more. Very, very frustrating - I've learned that if it isn't on the shelf where I can find it, there's really no point asking a salesperson unless I'm trying to work on the Zen of Patience and Tolerance.

Cindy -

If you get the pod air filters, you can use them for your test then seel them to a shaved VN750 rider.

You can find them here http://www.z1enterprises.com/detail.aspx?ID=221

If all you want to do is test run the engine, you don't need air filters on it. You won't be running it long or in dirty air conditions.

That's all I want to do at this point - she got a couple days' stay of execution with the whole timing thing over the weekend, but if she still won't start, then she's getting parted out. As long as the clean air volume (from the airbox), etc. won't impact the ability of the engine to turn over or not (for her last shot, she deserves a fair test), then I'll just put the coolant system on and cover the boots with pantyhose and a little tape.
Thanks for everyone's suggestions~!
