BMC race vs BMC street vs DNA vs K&N
 

I've heard mixed feelings on these filters. Obviously I want the highest flow possible. What is the best choice for my SH with stage one jetting and after market exhaust?

What type of jet kit? I believe it is tough to get one of those kits running well with a high-flow filter.

Also, are you running a full exhaust or slipons? The resulting top-end will be negligible with anything but a full exhaust.

Plus, high flow filters essentially move the power up in the powerband, so you'll lose a smidgen of the SHawk's bottom-end power. So it may not be worthwhile if you don't keep the bike revved high.

whichever filter you get the jetting has to be changed and likely the needle position as well. I have the k&N and it took awhile to get right and I eventually took it to a shop to get running well. if you get a BMC go for the BMC race... just my $.02

I had a k and n and Jardine High mount race baffles, I have a combo of a Factory jet kit and a Dyno Jet kit in mine. Ran like a top. Kindof pricey though having 2 jet kits to buy.

Right now I'm running a Dynojet stage one kit (#1185) with the needle in the sixth slot and 190/195 mains. What parts of the two different kits did you utilize?

Here's something I read recently about Air Filters
 

from the RC-51 list , interesting.

Yeah I read that same article. On most bikes with a tuned airbox the stock filters seem create more power. I'd love to save the $100 and use my stocker but its dirty and I don't want to pay $70 for a stock non-reusable air filter.

Very interesting article.....Thanks a lot!!

I think it varies from bike to bike. On the 1000RR they claim that the BMC makes more power and the K&N you can actually lose power. I don't think that comparison takes tuning into account though. I have a K&N on my bike and it runs just fine with the Factory kit.

I've read that but remember we do have a different motor/airbox and fuel system then the rc51. Plus personally I've noticed a difference between stock and the k&N. And that was after jet kit for the exhaust and stock filter then switching to k&N and exhaust

K&N, Factory Pro Kit, 48 Pilots, 4 degree advancer, Runs like a great.

My bike mechanic is very, very competent, an endurance racer, and a former Super Hawk owner. When I got my Jardine high mounts, I discussed a re-jet with him. He adviced me "to never, under any circumstances, put anything but a stock air filter in a Super Hawk." I didn't even bother to ask why. That was enough for me.
