just curious if anybody else has seen this .When I start the bike up there is significantly more top end noise while the oil light is on. As soon as the light is off the noise stops. This takes 1-2 seconds to happen unless it has not been run in a few days . After it has set for a few days the engine even idles slower until the oil light goes off then jumps up to normal idle. It has not always been like this , but seems to have started after the last oil change? maybe? any thoughts? Rick | ||

is the oil level ok? | ||

get a louder pipe  | ||

Got a loud pipe and the oil level is OK  | ||
| Brumbear |
get a louder one  perhaps the seal on the oil filter the inner one isn't seating properly and the oil is draining down if your using sythetics it shouldn't be a problem though | ||

I second that get a pipe | ||

It does take some time to get oil to the top end. Put your helmet on before you start the motor.  Here is a trick I have used for oil changes, might work here as well. Hit the starter then quickly stop the engine with the kill switch. You have primed/pressured the oiling system a small amount. Repeat until you are satisfied, get bored, or the oil pressure light goes off.  | ||

That's your friend gravity at work. The reason the light is on and there is more top end noise is the same......there's no oil in the top end. This is why they say the worst thing you can do to an engine is start it. | ||

What oil do you use? | ||

Mine has done it for 36,000+ s'miles. No worry get on it and RIDE!!!!! | ||

i am going to assume that the chain tensioners are desgined to use oil pressure to keep proper tension on the timing chain. this is the design that alot of chrysler products use. little or no oil on the top end of the motor(on the cam shafts or the valves) shouldn't change any type of noise unless it is driven for a long period of time resulting in perminant damage. | ||

Mine is a clattering cod of enormous proportions after a oil change. I use Amsoil 20/50 and I think that paper oil filter could be restricting the flow for that type of oil, possibly. I also think the stator went after the last oil change. I had removed the muffler to paint it and while that was off I checked for debris in the plastic basket screen,, of which there was none. I put in 3 qts, let it sit for over 1/2 hr and then started it, Gawd! The clatter was pushed to a new level and lasted way too long. I smelt a faint weird burning plastic smell and the stator gave up that afternoon in backup weekend tourist traffic of about 2 miles. And the horror stories continue,,, oh, Its important to mention that this oil change and start up was different from the others due to the bike being on my T-Rex stands during that proceedure.

Mine has done it for 36,000+ s'miles. No worry get on it and RIDE!!!!! thats what I was hoping to hear . I check the oil level regularly. I know the the bike did not do this when it was newer. I was just wondering if anybody else has had the same problem. I suspected the filter causing a restriction, but it has been the same buell branded filter on every oil change. having the idle drop 500 rpm when the oil light is on is a little concerning though.

I would imagine the stock ecm idles lower until oil pressure is established and not some sort of frictional loss. | ||

I have never heard anything about the ECM registering oil pressure. It's not in the DIAG list of things the ECM monitors. Sounds unlikely. I would be concerned if my bike started making new noises. And you should too. If you are not keen on opening it up yourself have the internals looked over by your mechanic. It's not all that common but stator nuts do come loose, and there are a few instances of balance gears self destructing (improperly machined ones). Sure there is some piston slap and top end noise on each and every start up, but it should go away as soon as oil pressure comes up and the engine starts to idle normally. | ||

My oil light isn't even on for 1-2 seconds, no matter how long it sits. | ||

Do you think that the startup rpm variances between no oil pressure and oil pressure are just frictional losses? |
