What oil filter do you all use?
I know Purolator "Pure One" filters are the best.
I'm just trying to figure out which one I should get.

I got the PL14160 (the longer one) I hope it fits and is the correct one!
The shorter one is PL14162 I believe

These are the correct model numbers for my friends R1
thanks alot

 

i used a fram, i try to change the oil every 3k, i think there all about the same nowadays, as long as you change them when you do oil you should be good

 

Update.
I installed the P14160 Purolator "Pure One", which "Pure One" is the best filter and used Shell Rotella full synthetic 5w-40.

I've driven for at least 40 miles now and no problems.
But I was worried because on the right side of the bike theclear screen where you SHOULD be Able to see oil flowing in the engine.... I see no oil in it.

My friend has an R1 and when he starts his bike up you can see oil flowing.

WTF?
thanks

 

1 bike off
2 bike level
3 oilshould cover 3/4 of the window

 

well it doesnt have ANY oil in the transparent clear window (on or off).
On my friend's R1 you cant see oil until you turn it on.
I KNOW I put in enough. It calls for 3.6L when installing a new filter.
I probably even put in too much.
Man, I would love to rebuild this engine and start fresh as well as diagnose any problems that arises.
I LOVE chokes now. Its like a decent option which will let you get the engine moving without having to disconnect fuel (and/or) spark, so that you can get oil flowing through the engine Prior to starting it on a fresh oil change or after a rebuild.
^sorry for the run-on sentance

 

then tell ur freind he's low on oil, it's a sight glass to see the oil. litersand qaurts are different

 

^+1 1/2-3/4 sight glass level. With new oil, a flashlight is nice to have to view the window level.
