I'd be interested in knowing how the 07' oil pump performs in regards to engine cooling. Anybody know more about that pump then just what it looks like because I've already seen the photos. Apparently Buell changed it to pump and scavenge better. Maybe the next Fuell mag will fill us in. | ||

My Ulysses' oil bag temps are between 190 & 195F. That is after a good 40 mile flogging on the freeway at speeds >65 mph. Not sure if the oil needs more cooling with those numbers. | ||

I guess EG's thinking that if the new pump flows more oil, more heat may be transferred from the engine to the oil, resulting in cooler engine temps, less fan operation, less tendency to spark knock, etc. | ||

That's right Whodom. ULY's are air/oil cooled and when it's raining it's also water cooled. I'm thinking heat transfer from metal to oil. If the oil jet volume hitting the bottom of the piston is increased it seems reasonable to me that the temp of the piston will be reduced. This would hold true for all parts in contact with the oil. Then the fan should come on later and make actually go off once in awhile. Buell doesn't redesign parts just for kicks so I'd like to know what their reasoning is behind the change. | ||

Does the Uly have a thermostat that allows the oil to warm up before allowing it to go to the oil cooler? If so, at what temperature does it start to flow? | ||

Buell doesn't redesign parts just for kicks so I'd like to know what their reasoning is behind the change. No doubt. You know, last year they introduced the improved oil pump drive gear, which supposedly takes care of the occasional failure there. Maybe they ran that for a year to ensure that the new gear is bullet-proof, then they decided it could handle some more load and they upped the capacity on the oil pump now that the gear will handle the extra load. Aeholton- I don't believe the oil cooler flow is thermostatically controlled. Some people cover the cooler up in very cold weather. | ||

I looked that up in my service manual and answered that a couple of weeks or so ago. Oil cooler is not thermostatically controlled. | ||

My bike uses about 7/8 of a quart about every 1000 miles. I think most of it is go out the breathers into the intake. I wonder if they didn't improve/ increase the scavenger side to dry and keep the sump "dryer", which in turn may keep down the amount going out the breathers????? | ||

Gowindward - 7/8ths of a quart every 1000 miles seems excessive. Are you changing your own oil? If so, only put 2 1/2 quarts in it at the next change. Run it and check it hot. See where the level is. Don't fill it beyond that point. See if this limits your "blow by". I don't add more than an ounce or two (if any) between changes every 2500 miles.

I've got about 3,000 miles since my last oil change. I've added maybe 10oz of oil in that time. I check it after each ride, and the level is always different. Sometimes up near the full line, sometimes near the add line, sometimes in between. I don't plan on adding any oil unless the level falls below the add line. | ||

I do my own service work, and I don't add oil until it's at the bottom of the dip stick....yes, check it hot yada..yada..yada... I know the routine.  | ||

Chadhargis Posted on Thursday, August 17, 2006 I check it after each ride, and the level is always different. Sometimes up near the full line, sometimes near the add line, sometimes in between. I don't plan on adding any oil unless the level falls below the add line. I agree with the above statements and add that I have noticed the oil level changes on my Ulysses too. But seems to vacillate between 1/2 and 3/4ths down from full register. | ||

Make sure you always check it on the level. Bike is leaning on sidestand but pavement is level like in your garage. |
