I did a search on this and found some good info but nobody seemed to have the same problem. During my ride to Buelltoberfest I had my oil light come on after filling up with fuel. I shut it off and restarted and it was on again so I revved it up and it went out. This happened a few more times during the fest. On my way home I had to slow down from 75 to 65 and it came on again so I down shifted and it went out. I up shifted and after a few seconds it came back on so I down shifted again and held it at higher rpm until I was able to increase my speed. As I neared home it came on at 75 so I down shifted and it went out. I up shifted and it remained out. I stopped for gas, restarted and it was on again so I revved it up a little and it remained on so I revved it up high and it went out. Now at first I just figured it was a bad sensor but my tappets are making noise too so now I'm thinking I do have a problem. I made it home and will make up a pressure gauge and see what's really going on. I read that in 07 they made some improvements to the oil pump by increasing it's size so is the 06 pump just marginal enough to fail at 25,000 miles? Anybody else had pressure problems with their 06? | ||

07's came with all the latest and greatest gears and such that would work on your bike. What oil and filter are you running? | ||
| Tootal |
Purolator pure one and amsoil 20/50. I thought about the filter when it first started. My thoughts were that if it was really dirty and was not allowing it to by pass then it would cause my problem and since I had over 4000 miles on the filter that could be it. I picked up a new filter and filled it with amsoil and put it on but it didn't make any difference. I've been using this combination for a long time so something else had changed. Good to see you Froggy, hope your ride home was a good one! | ||

Was the replacement filter also a Pure 1? http://www.purolatorautofilters.net/products/pages /motorcyclefilters.aspx | ||

You need to get a manual oil pressure gauge on it as soon as possible. If it is an oil system problem you want to know what it is before you do a whole bunch of damage. If everything reads normal, change the sending unit. | ||

Well I ordered an 07 oil pump this morning. Figured the upgrade sure couldn't hurt anything. Thanks for the link to Purolator. Good info. I am looking into putting an oil pressure gauge on the bike but will wait till the new pump is in. For now it's considered down for parts. With the cooling temps that big Road Glide is looking pretty good. Puts a big hole in the air!! | ||

Tootal- The first question is did you check the oil level? You didn't say, but hopefully that's the first thing you did. Definitely check the actual pressure with a gauge. The 07 pump has a larger scavenging section but the pressure section is the same capacity as your 06 pump. When you drop the old pump, I'd pull it apart and check for debris or wear. I think it's unheard of for one of these pumps to wear enough in 25,000 miles to cause a loss of oil pressure. I'd check the lines going to the oil pump for signs of clogging, deterioration, or debris too. BTW- revving up an engine to make the oil light go out is probably not a very good tactic. If you've really got low oil pressure there's practically nothing worse you could do. Hopefully it does turn out to be a bad sensor. Good luck. | ||

Low oil level, restriction, worn pump gear, failing pressure sensor are about the only things that I can come up with knowing that you changed the filter the way you did.  | ||
| Tootal |
Oil level was checked hot and at idle. It was right on XX. I'm going to pull the check valve out and check for problems. I will pull the old pump apart and measure the thicknesses and check for wear. I will post any problems. I wasn't too worried as long as the light was out. Ball bearings and amsoil don't need a lot of pressure to survive. | ||
| Bartimus |
Have you had a chance to put an oil pressure gauge on the engine yet? ALSO, have you checked the oil pressure sensor??? I have seen these fail quite often! | ||
| Tootal |
The sensor was my first suspect but with the lifters starting to clatter I knew it was pressure. I drained the oil yesterday and started looking at the pump. It will be interesting if it will come out without pulling the muffler. I don't have a pressure gauge, I hope to get to a parts store today and see if they have one. If they do I might throw a new filter on and fill er up and see what it's doing. Wouldn't hurt to flush the system before installing the new pump. | ||

Just a thought,make sure the cooler flows. Blow some air through it both ways. | ||
| Tootal |
That's a good idea. The oil gravity feeds the pump and then it goes through the cooler and then to the filter housing where the pressure switch is. I will check that. | ||

Well, the problem was found. All I had to do was look in the mirror!!   It seems that 5000 miles ago I grabbed the filter off the shelf and spun it on with some fresh Amsoil. The only problem was I grabbed the filter for my CAR! They look almost identical on the outside. The car filter is roughly a quarter inch longer with the same diameter. The car filter has a 20mm thread that seemed to screw right on the Buell 3/4' thread!! I looked up the specs between the two filters and they are the same so I don't know why it caused me problems. It ran for 4300 miles before my idiot light came on and then I put one just like it on and still had the problem! That's just weird. I now have the proper filter on with fresh oil and implemented a temporary oil pressure gauge. I fired it up and the lifters still clattered for about 30 seconds. (Yes I put oil in the filter before I put it on.) Then the pressure gauge jumped up to 35 psi and the lifters went quiet. I let it idle till the filter got hot and the pressure was still at 20 psi at idle. Like I said, the filters are almost identical. I still don't understand why the one worked for so long before causing a problem. Bottom line, I might still have issues but for now it's running quiet. | ||

There is a continual debate regarding the use of oil filters not recommended by the manufacturer for the Buell or other motorcycles. It may or may not be a problem. I personally will not use a filter unless it is rated for the motorcycle. Why take a chance just to save a couple dollars? See the recent thread. http://www.badweatherbikers.com/buell/messages/142 838/600319.html?1288059379 | ||

I had the same thing on my 06 Uly. The light coming on was the result of a loose battery terminal connection. Check the sender cable (make sure it's not loose or has a short). Check the battery cables and make sure that they are tight. | ||
| Tootal |
Terminals were tight, I checked before leaving for Buelltoberfest. The lifters were getting noisy so I knew the pressure was low. The filter I normally use is what purolator recommends for the Uly. I've been using this filter, except at the last oil change, since the bike had 100 miles on it and I use the same brand filter on my Harley with over 80,000 miles on it. Purolator makes the filters for Harley. Hey Fatty, I saw you at the Telico Cafe but figured I'd see you at TWO but never did. Sorry I missed you. | ||
| Ft_bstrd |
Sorry I missed you. I've met you before, right? | ||
| Hughlysses |
Glad this turned out to be something simple and non-fatal to your engine. Did you go ahead and install the 07 pump? Weird about the filter working for a while and then causing a problem. | ||
| Xbimmer |
Then the pressure gauge jumped up to 35 psi and the lifters went quiet. I let it idle till the filter got hot and the pressure was still at 20 psi at idle. According to my '06 FSM, a new-spec oil pump should run 7-12 psi @ 1000 rpm, and 10-17 @ 2500. Those numbers you have there seem a bit off to me, unless pressure is supposed to increase down the line. I'm also interested in how things turn out for you with the '07 pump. | ||

Jeremy, we have met but between recognizing ones forum name and then trying to remember their real name it's tough, well for me anyway. I've been at Buelltoberfest the last three years. We met originally on Friday three years ago in the parking lot of TWO. You had your Fat Bastard shirt on so it was easy for me. Next year I'll make it a point to find you. Hugh, I haven't received the pump yet. On order. Go figure! I talked to a couple of guys in the shop today and we surmised that the original filter got clogged up so bad that it started bypassing. At low rpm it didn't have enough pressure to bypass so the light would come on till I revved it up and it could bypass and the light would go out. Since I was at highway speeds it probably bypassed a lot. When the light kept coming on I replaced the filter with a new one. At first the problem seemed cured as I had no more problem for a couple of days and then it started again. We think since the old filter was bypassing the oil was really dirty. The new filter started cleaning up the mess until it was clogged then it started bypassing. I think that if I had changed my oil too it would have lasted a lot longer. Dean, I'm sure my oil was not up to HOT yet. The filter was pretty warm but I could still touch it. I was only idling in the garage for 15 minutes or so. I had that temporary gauge on there and couldn't ride it. I'm sure if I had ridden it for 20 minutes the pressure would have been a little lower. When I shut the bike off the fan did come on but the oil was not up to temp all the way. |
