Just bought an '02 919 yesterday and kind of excited about getting back into riding after not owning a bike for a few years (decades). My youngest son is an avid rider and helped me check over this bike and rode it to my house after the purchase. I haven't rode it yet and won't until I go through some maintenance and minor repairs. I removed the seat and side panels to find some wires with mouse chewings. Then I opened up the air filter box and found the mouse home. Let the TLC begin. 20200522_173958a.jpg20200522_195824_Burst04a.jpg20200522_201121a.jpg
Welcome. I'm surprised that the bike even ran with that air filter like that. Good bike.
It will clean up fine.
I modified the air intake on my bike. No filthy rodent is going to live in my bikes air filter.
No its not a common mod.
It does fuck all but look cool. Removes flapper valve and make some noise. And rodents don't live in it.
Do the flapper mod. Because the flapper valve is bad for performance.
Keep your OEM air filter cause the K&N filter is shit for performance.
I should expand on my K&N filter comment.
I noticed a negative impact at low revs, low speed. Especially at steady throttle. Like when your crawling through traffic.
The revs were hard to maintain at a steady and throttle felt very abrupt.
Once the revs and speed were increased I didn't notice much difference between the K&N and OEM.
