Lots of outrage from owners and denial from the MoCo. Anyone know about this this issue?

LuciferMuttDec 30, Watch this:. ADV Sponsors. Then again I had a TC88 and it didn't eat it's cam chain lifters in the 60, I had it either. The thing about the internet is if there are 1, people who have no problem at all but 3 that do, you are more likely to hear from those 3 than the others. I think you may have greater risks with stray lighting bolts really I researched the issue too and it looks pretty isolated to me. Seems to be mostly big bore kitted bikes that do it.

Also found that the Evo engine some had the same problem. I'm into unmodified bikes these days that are quiet and don't shake, still considering a FatBob or the FXDR once the price settles down. I wouldn't worry about the sumping on a stock bike and I've already been struck by lightning. His second SG and at least his 7th Harley.

The issue is real but he has gotten little to no support from the dealer who will never get his business again. If this issue is handled the same I expect the other posters to be correct. Only effects a small number of bikes. Expect the issue to be minimized by Harley and other owners. Pay big bucks to fix a problem you will be told does not exist or is your own fault. Superbikemike and alekkas like this.

Not sure if this is the same one but similar to the link. KingOfFleeceDec 30, Our cam tensioner on a twin cam 88 was toast at miles.This is what I read on the international forum also. I want to go Stage 3 so, I will wait and see what folks say about models. All the transmission fluid moves over to the primary. No known fix from MoCo yet. It is possible for some ci stock engine to have sumping issue, especially ones that are revved out to higher rpm, it does not happen to all of the M8s. Just some.

Some owners have reported engine power loss, others reported heads getting too hot to touch. No doubt Harley will find a fix, just a matter of time. Unfortunately, if Twin Cam engine is anything to go by, it takes MoCo a few years to nut out issues.

I spoke to an independent HD tech the other day and he said that a few of the new Milwaukee 8 motors have been burning excess oil and some have had their oil pumps fail I know there can be teething problems with a new design but using oil is unacceptable I think.

Bugatti run their Chiron engines at red line for like eight hours straight to test them. HD rigorously tested the new Vrod engine, why wouldn't Harley do something like that for the M8? If I'd know this I might have had second thoughts of buying a new Fat Boy. In kms since its first service the dip stick is showing it needs a top up but just a little I think.

All new motors burn a bit more oil for the first few thousand ks right?

Posts: Castlemaine. I was told that as long as I didn't go past stage II on the motor I wouldn't have an issue Posts: Strength in Unity. Posted by chinashop bull on 22 May PM M8 motors are not burning oil and oil pumps are not failing. Some are wet sumping when the scavenge pump is not getting oil out quickly enough.

Posted by chinashop bull on 23 May PM HD also have a bulletin for sumping only it hasn't actually stopped sumping. Put a cold spoon on my desire for a harley that's for sure.

As the crank shifts, even a little, the oil pump is not as strong to scavenge all the oil out. We've seen this more than a few times. Aftermarket fixes will undoubtedly void the warranty Rumor is that HD is working on new cases for the M8 in an effort to fix this on upcoming models.

Classic Triumphs have this problem if they sit too long without being started, but the oil goes back where it's suppose to once you start the bike. Not sure if this is the case with Harleys. Message Mykneesbehurtin. When i dropped my trike off at the dealership i was talking to a tech and he said he was working on a trike with miles on it blowing oil out of the air cleaner.

The dealership strongly recommended the Cam Plate and Hi Volume oil pump to accompany the engine upgrade. We all know the bigger the engine the more heat is produced. Moving oil always helps with engine heating issues.

My stock run was After the build my numbers were The Cam Plate and Hi Volume Oil pump handle the extra stress of the engine without issue to this day. If you are contemplating any internal performance upgrades, this item is a must. Date published: Having built high-performance engines in the past, I was somewhat concerned with the relatively low oil pressure inherent in OE Twin Cam engines.

If oil is the life's blood of an engine, the oil pump is the heart. I replaced the cam plate, oil pump, cam-chain tensioners and inner cam bearings myself, in about 3 hours. While my hot oil pressure at highway speeds was previously around psi, it's now at around psi, depending on the weather.

Most importantly, my hot-idle oil pressure went from barely registering on the gauge, to around 15psi. More oil circulating through the oil cooler means cooler oil, and I can certainly tell the difference. Oil temp has droppedengine temps have dropped, and the valve-train makes significantly less noise. If I had it to do all over again, this would be the very first modification performed on my bike.

I am sorry about his bike woes. Yesterday with the approval of HD they did the Sumping test and surprise surprise it didn't exhibit excessive oil in the sump I was hoping they would just order the replacement oil pump and be done with it I wanted to vent my frustration with HD Australia but sadly they won't return my email request I'm not looking to put the boot into SunCity Thanks for the reply.

Harley-Davidson Milwaukee 8 Engine Problems!

I hope this is the correct place for this discussion:. Feb I upgraded my Deluxe to a new M8 Road King, very happy with the bike, did a ride to Adelaide and return and it was like sitting in an old caddy, km days without and problems Job done and a good run-in process slowly released what should have been hp of even fun.

What happens and usually during a long ride, say km and as the motor warms up it starts to dump oil into the sump, the HD being a dry sump would normally via the scavenging side of the oil pump return that oil to the general circulation. However the pump can't keep up and eventually the crank starts running into a wall of oil.

More capacity would be a good thing for all oil changes So, why haven't they figured this out earlier?

This is the third production year for the M8, right? So when they designed the new M8's, they didn't measure oil flow? By shear volume, their Nath is off.

Old New This is based on a filter 3" I guessed, but the diameter is the same for both. HD is not the only company doing this. Honda made the tank on the new wings smaller and since it more efficient, it is supposed to equal out. Why do these companies assume we won't do the math. I bet they think this may help the sumping issues I have always been a big fan of larger oil filters However why now as Alan said in his post. The MOCO is up to something here, look how many oil pumps they have redesigned already in a quest to fix the oil problems on the M 8 engines.
