As some of you know, I have occasionally posted about a noise that sounds like a spun bearing that would happen for a split second on my bike. I have not heard that noise in a while, until I changed my oil a few days ago and once again the noise has returned. It always seems to happen when I change my oil and for a few hundred miles after I change my oil it will occasionally happen. The oil change has to be related, I just dont accept the its a coincidence. I believe it may do it if the bike sits several days without being ridden though that rarely happens with me. Any thoughts on what this could be?
Your fellow SVTC owners will have input for sure. But from past experience I've had bikes that had clutch chatter after oil changes. Newer oil slips more between plates and would chatter. After the oil had a little age on it the noise would go away. I've owned several bikes that had heavy duty clutch plates and springs that would do this. I'm sure the SVTC has a heavy duty clutch. Anyway, just an observation from other bikes.
sometimes when my VS650 is cold (40F or less) after riding about 2 miles down the road and stopping for a red light, when I let the clutch out to take off it would make a noise like I was aggressively scrocking up a lugie. Everytime its happened I pulled the clutch in instinctively and let off the throttle, and then its gone.
I have tried to visualize what could make a sound like that: clutch plates chattering?
Timing chain gone completely slack and dragging alone the inside of the engine case?
Its only happened maybe 5 times in the last 3 years, never twice on the same day.
Hey Rob, a couple questions and in no way am I trying to be demeaning.
1. What oil are you running?
2. Are you adding the exact oil amounts to BOTH the oil reservoir and the crankcase?
but no, dont try that, unless you know someone that can pick up the bike and hold it downside up.
Get a CLEAN pan to put under it and change quickly, then just add it back in.
I personally noticed a reduction in “engine noise” when I went from regular oil to a full synthetic . Thought I’d mention that.
KCW and JonMaz2112 like this.
You should lose very little oil when changing just the oil filter. At least that is the way it works on everything else.
if the filter is between the pump and the bearings, very little oil would flow from either end when you take it off.
