k&n filter bags
Someone is going to find this info useful..
I spent 4 hours today riding in shitty shitty rain, from State College (Penn State) coming back to Philly.
Pretty much torrential down-poured the entire way.
My 79 cb650 has velocity stacks on it which means I should not be able to ride in rain at all.
So… how’d I do it? How’d I make it home?
My bike should’ve bogged down and sucked in a shit ton of water and cut-out and left my stranded…
First, what are velocity stacks?
They are usually metal cones that go in place of where your air filter, or pod filter would be. It goes from a large diameter to a smaller diameter, which helps speed up the airflow going into your carb, which makes more power. Essentially it’s the Venturi effect. Big to small will increase speed/pressure. (or something like that. I’m not a scientist.)
Long story short velocity stacks make the most power compared to pretty much anything else. Def more power than pods, by a long shot. So increase your jets a couple sizes…
Anyway… there is no filter element at all. Nothing except maybe a screen to keep dirt, and bugs out. So… when it rains, you’re fucked.
A few years ago I came across these:
K&N Filter Bags
They keep 100% of the water out and let all the air in.
So, I’m sure someone right now is thinking… “uh, I have pod filters and I ride in the rain all the time with no problems…”
Yea, well… my response would be that riding around Philly for 20 mins in the rain is a hell of a lot different than riding 4 hours in a down-pour… Not silly dumb rain… I’m talking about shitty down-pour. Rain will drench your pod, It will get in every crevice, and it will be so dense with moisture that the bike straight up will not run. And you’re fucked. Adam and I have learned the hard way.
Do yourself a favor and pick up these bags if you do any long distance riding in the rain and you have pods.
Or… get some velocity stacks and make some real power, just keep the bags under your seat or something… just in case it rains. That’s what I used to do. But I ride everyday rain or shine, so I just keep the bags on always now.
…Just my input. I wish I knew this info 4 years ago.
Would’ve saved some hours sitting around waiting for the pods to dry out.
Or, be boring/safe and leave your cycle stock/slow. ha
