DIY Pods

Here's what I did. I await the feedback.

Seriously?
Well, OK.
Don't take this wrong, but...
There is no laminar airflow in though those pods and I should expect you would have some serious funky lean stumble problems at various speeds, along with surging in crosswind conditions, much worse than the ones experienced by current pod users. In a heavy rain, fog or mist I would expect serious performance issues. The filter media is nowhere near adequate and on the filters with the missing chunks....guess where they went? Guess was was on them when they went there? Guess where it is now?
On the other end of the spectrum, the open pipes with no back pressure will very likely burn and/or warp your exhaust valves.
Your tappets sound WAY out of adjustment.
On the average, I'd give this motor another 5-7000 miles before it starts showing serious signs of deterioration like loss of oil pressure and compression, high oil consumption, etc.
As for your starter issue, sounds like a dead spot in the commutator or bad brushes.
Not trying to be a downer, seriously. And I could be wrong. But I don't think so.
Anyway, you get high marks for originality and creativity!

 

One thing that immediately comes to mind is that ABS plumbing pipe is not so heat resistant. CPVC would be a better choice. On a hot day, sitting in traffic, the ABS might get "saggy".

 

CaptainKirk, thanks for the input - no offense taken! I'll definitely look into that tappets thing you mentioned. I don't do much of any wet condition riding any more cuz last time I did, I bogged all the way out at a stop sign! As far as chunks of filter in my engine; when the media tears, it's more of a stretch and tear than a chunk being pulled out. Never been too worried about muckin up my carbs or engine. The exhaust is a temporary set up while I gather funds to do something better but trust me, I know better than to run open like that for too long!

K-moe, if you're sitting in traffic on a motorcycle, there's something wrong. If your carbs are transferring THAT much heat from your engine, something's wrong. Also, I don't think I've ever seen cpvc in 2" - besides the black abs looks awesome!

Thanks guys!

 

ABS melts at 221ºF, and begins to bend under it's own weight at 170ºF.

I'm glad that you live somewhere that has no laws against filtering through traffic. Sitting at a long light, or waiting at a train crossing, is a reality in most of the U.S.

I gave you that information because you asked for feedback. I've made intakes out of PVC for other motorcycles, and found them to be lacking in durability.

2" CVPC is easily painted.

 

Another possible concern is lack of filter area. Looks like you have 1 flat piece of filter media 2" diam for each cylinder. That's a total of 12 square inches. 12 square inches is significantly less than the area of the stock air filter, and the stock air filter is convoluted media, so probably has much higher per square inch, and also take longer to loose flow as it gets dirty.

Pods aren't just tubes with a filter in them acting like a sieve for dust; they provide a large filter area by effectively being a tube made of filter material.

 

maybe if you put a piece of screen door screen in first then the filter media the media would be supported and not tear through
