I just converted my 650 to a spin on oil filter. I used a wix 57013 for an older Harley plumbed into the feed line from the oil tank to the engine. I got it hooked up and it seems to be working fine after getting the air out of the oil lines I have plenty of oil pressure, but when I shut the bike off the oil pressure doesn't drop right to zero like it used to, the gauge drops down to 30psi or so and takes a minute or so before dropping back to zero. The bike wasn't fully warmed up when I tried it but I want to make sure everything is ok before I start riding again. Thanks!
