Also @beanz690 ... here's a video showing Sprint filter vs BMC vs stock paper. (testing starts at 10 minute marker of the video)

I do recommend not running the stock filter and using the BMC street filter with this tune from Deussen as they come running rich , your going to need more volume of air to compensate ... also a video of my bike running with Deussen tune as well. I've opted for Deussen's signature decel pop which is why you hear it crackle when reved, have plenty of videos on my youtube to check out if you like.

Thanks buddy! I’ve actually seen lots of your videos on YouTube when looking for bikes with the spark exhaust. Although, yours is the full system and a bit different than the 3/4 slip on it ultimately influenced my decision to go with the spark exhaust.

I don’t know how much of a conclusion I’d draw from that video. Interesting thought though. If I was in a particularly dusty or sandy environment I wouldn’t opt for the Sprint P08, but I’m not a fan the oiled filters either.

I just ordered a P08 from motomillion locally here in Miami. I don’t think it’s dusty here but may be wrong..

Glad to hear my videos helped you. I bet your loving that spark system ! Sound raw doesnt it?!

Just be aware with the P08. Over the long run it for certain wont be protecting that motor like a cotton oiled version would. Ultimatly paper filters the best but when you have a tune going , paper will cause more restriction as the engine is calling for more air due to the increased fuel map.

Ive ran the p08 , BMC RACE and the BMC STREET and both filters were exceptionally better than the p08 in terms of catching debris. Im in NYC so there is no dust here, and trust me when i tell you my filters caught alot when i removed them to inspect after 500 miles. As of today i stick with the BMC street for peace of mind.

If you can see your hand through the filter .... be sure a lot of stuff is getting through that filter....

I'd love to see some research on this. If a filter has, let's say 15% more flow, how significant of a difference is that really? How dirty of an environment is one operating in? What is the typical size of an airborne particulate in a given environment? One filter spec I saw gave a value of 1.5" of Hg when doing CFM comparisons, but what is the significance of that particular value? What does a V4 pull at idle vs. WOT? All questions.
