wow..this is going to be a dumpster fire for them if it isn't fixed..crossing my fingers for you and everyone doing this!

 

My Stage 1 2017 Road Glide Special with 11,000 miles was just diagnosed with the sumping issue and failed lifters! I am thinking about going to Stage 3 since most of the labor would be covered but am concerned that the extended warranty I purchased with the new bike will not cover the new parts. Plus, what other issues could arise because of the failed lifters? Any thoughts would be appreciated.

 

I think that the new oil pump should be installed on all the M8's. I am looking into a cam, if I do that I will have the oil pump changed to the newest latest greatest oil pump. Or I will wait until S&S makes their oil pump and install it with their cam lifters etc. etc.

 

I have one of the first production stage 3 kits and have no sumping after 4,000 miles. Apparently there were good oil pumps in some of the kits.

 

What is your riding style? Have you put a good load on the engine for an extensive time? For instance, doing highway speed 75-80 mph for 30-45 minutes consistently?

If so, and no issues, then you are lucky indeed.

Have you had the crank sensor removed and checked for oil after said riding?

I am not doubting you, just curious. I spoke with someone not long ago who had 3800 miles, but it was all city mileage with a lot of stop and go. Remember, if you ride hard, but then idle for a while, the pump recovers the oil and the issue doesn't show it self. There are a some factors here that may prevent you from ruining an engine, even though you do have a sumping issue.

 

Ive asked in another post. Please educate me. What exactly is the Sumping Issue ?

 

From what I understand, sumping occurs when oil accumulates in one part of the engine but does not circulate into other parts of the engine. Pressure builds up causing a leak and/or parts that needed to be lubricated fail for lack of lubrication. Apparently it has to do with the capacity of the oil pump. I have been very careful with my bike (service and watching fluids etc) but last Sunday there was a sudden spraying of oil onto my right front exhaust and platform. HD has a Service Bulletin out that takes the service tech through several steps to determine if sumping is the issue. The first is to check the level of accumulated oil (no more than 3 oz and I had 7 oz) then check pressure then open the CAM area and check the pump and lifters. My pump was damaged and the lifters had failed. Oil jets that spray oil on the heads were also thought to be wrongly torqued (my were fine) This is my simple understanding of the issue.

 

I will chime in on this,

13K miles on my stage III. kit was installed before delivery. bike is all HD

I cruise at 80, its my go to speed. Been across country and back, Death Valley and the coast. Many Many miles two up and loaded down over the Mountains out west. Road Trips are usually 500 mile days. Bike has never given me reason to fault it. I did my own sump test as per the SB and there was only a dribble in the case.

My dealer has a new pump for me, but HD will not install it unless there is an issue and currently there is not. Im on the fence to give them my bike and let them tear into it anyway, if its not broke dont mess with it mentality.

Still on the fence, If there is an advantage to the new pump, I want it. but no one can say what the new pump does.

I live to ride, I will put the new pump in on my dime if I knew it what it was going to do.

I already posted on here that There are more questions than answers.

 

Its very important WHEN you check the crankcase for excess oil to determine if its sumping. If you let the bike idle for any significant length of time after you stop, you may not get a complete picture as to whether or not you have a sumping issue. Personally after 3 engines being installed in my 2017 CVO Limited, I'm starting to believe that most early M8s have or will have a sumping issue. But its easy to confirm to be sure.

After the engine is well heated (20-30mins of riding), ride on the highway for 50 miles and remove the crankcase position sensor according to SB1450 or have a dealer do it. If you spend any time idling before you pull the sensor, then the oil pump may have enough time to remove the excess oil in the crankcase.

SB1450 is very specific. Let the engine idle for 45-60 secs in upright position and then remove crankcase position sensor within 1min.

if you don't follow these instructions, you might still have sumping while running at higher rpms but when you pull the sensor, there might only be a little oil in the crankcase because the pump was allowed to catch up. Therefore you are not REALLY seeing how much oil is in the crankcase while under normal highway or higher rpm operating conditions.

 

I did follow the test to the letter, I found the SB odd in that they want to idle at all. They must have their reason to test as they do, I wish there were more details and getting info from the dealer is useless, they have the same SB and know no more.
