Hey y’all, kinda new to the forum talks. I have a couple questions. So I have a 2011 Stryker with 13,500 miles on it. I’m in need of a desperate oil change so I am hoping with the oil being so old and broken down I having issues. Today while riding, after my bike heated up (30 mins) into ride, my bike was making a rubbing feel. Outside temperatures were upper 90s with a real feel of 110. Once the bike was hot any time I would down shift or decelerate it would have a rubbing feel. Felt like it was transmission related. For example in 3rd gear at 45mph if I let off and hit 40mph i could feel it in the bike. I say rubbing because it wasn’t bad enough for me to be concerned something was going to break. So I think the motor and trans share the engine oil together in this bike, so in other words there aren’t two separate drain plugs or fill areas? Please correct me if I’m wrong. The bike looked to be good on engine oil capacity according to the window. Has anyone felt this feeling? When I down shifted it only did it as soon as I let the clutch out. Never felt it on acceleration or while cruising. Only on decelerations and downshift. Also I have a tiny bit of oil residue around what looked to be a sensor in the bottom of the engine, it has two hex key bolts. I’m wondering if I should just change the oil now and see if it helps, but if it’s a clutch issue and the engine and trans share the same oil I don’t want to waste Oil and filter for something that will just have to be drained again. Current oil is on about 5000 miles since last changed. Thanks for any responses!
