2003 XB9R, Bike has 14.5k miles on it. Oil changed regularly. The low oil light came on, on the instrument panel. Next the engine started sounding bad, like I'd cracked a header pipe or something. I pulled all the parts around the engine off to see what I could see, no leaks, oil level was acceptable. I have drained the oil out at this point and it looks fine. Though I'd try changing the oil and filter and see what happens. Any thoughts/suggestions or ideas? | ||

That is a oil preasure light not a low oil light. You may have damaged your oil pump or oil pump drive gear. Drop your oil pump and see if the drive shaft on the pump is locked. Then look up into the hole the oil pump came out of to see if the oil pump drive gear still has teeth... | ||

Did you hear valves/lifters chatter or clack real loud? | ||

Don't panic. All of the bearings are rollers. The oil does more to cool than lubricate. By the way are you using HD 360 or something else? | ||

Yes, I heard valves/lifters chattering and making more noise than ever before. I've been using Mobil 1 20w50 (summer) and 10w40 (winter). Same as I'd used on my Buell S3. Right, the oil pressure light came on. I'll check on the oil pump. | ||

I say use your personal quote...not trying to be a dick either..... | ||

The syn oil probably saved you. Check the oil pump. It is the HD XL's week link. I would replace the pump and ride! | ||

Check the oil pump. It is the HD XL's week link. I would replace the pump and ride! The week link is the gear on the crank that drives the oil pump. The factory came out with a high performance bronze replacement gear (already installed on 06 bikes) this year. Check the "oil pump drive gear" threads in the Knowledge Vault. The teeth on the drive gear on some bikes wear to a knife edge and eventually they break off. This appears to be a pretty common problem on tubers; much less common but not unknown on XB's.

I stand corrected. It is the oil pump drive that is the week link. | ||

Oil pump was locked up when I dropped it down. I ordered the high flow gear a while ago. Now I need to see how easy that will be to install and if I'll have to drop the headers. Thanks! | ||

Now I need to see how easy that will be to install and if I'll have to drop the headers. It's a pretty big job on a tuber; it may be worse on an XB. Here are the major steps for a tuber: 1- remove exhaust, seat, & fuel tank. 2- rotate crank so rear valves are both closed 3- remove rear rocker cover and pushrods 4- rotate crank so front valves are both closed 5- carefully remove side cover. If you're lucky (I wasn't) cams will remain in place and you won't have to fool with the front rocker cover or re-installing the cams 6- lock crankshaft using widget available from American Sport Bike, remove crankshaft nut and old gear 7- install new gear and reassemble everything using new gaskets If your oil pump is locked I'll bet the gear fragged and some of the pieces got into the scavenging side of the pump and locked it. You probably need to disassemble the pump, make sure there's no damage, clean it out throughly and flush any debris out of your swingarm too. Also make sure the area around the cam gears is free of debris and that there's no damage to the cam gears. The new gear isn't really "high flow" (even though it's called a "high performance" oil pump gear), it's just made of more durable material than the original. | ||

Yeap as much work as I thought. Would that tool to lock the crankshaft be the "XL/XB Primary Locking bar"? So I have to open the primary cover too? Thanks. | ||

T9r, No, you want the "Pinion Gear Nut Locking Tool": http://www.americansportbike.com/shop/cgi-bin/cp-app.cgi?usr=51F5608235&rnd=2283 470&rrc=N&affl=&cip=65.87.143.25&act=&aff=&pg=prod&ref=16082&cat=&catstr=HOME:s3 engine You won't have to open the primary cover. | ||

Here is where I'm at now with this problem. Tearing things apart/inspection http://www.badweatherbikers.com/buell/messages/32777/214053.html?1153162980 |
