I just traded in my 2017 CVO Pro Street Breakout and a 2017 Low Rider S which both had the 110 Screaming Eagle Twin Cam for a 2018 CVO Street Glide in the Gunship Gray.

 

Thanks. I just assumed that all 2017 bikes went to the M8 motors.

 

 

extreme paranoia is taking hold of this forum lately..go have the time of your life this Summer on your new bike..it's Live to Ride, Ride to Live..not Live to Read, Read to Live

 

my dealer and a Harley tech were pretty honest (I hope) before I bought my bike. They said the twin cooled and stage 3-4 kits have seen some growing pains, but the standard 107 (I was looking at road kings and street glides) have been reliable so far. Obviously there is a percentage of failures with anything but you get the drift. Called a random tech in a random state and asked what he has been seeing, same response. Could have been bs, but I decided to get thr extended warranty just in case and have faith that the moco cant afford to have catastrophic failures on every bike sold. Just not doing stage 4 and enjoying it is my plan.

 

well said, just seems perspective is lacking, and see more new owners posting lately after reading here that they are now scared to death to ride and enjoy their bikes, and others contemplating buying not doing so because they are believing some of the misguided perceptions being propagated here..sure there's problems..but there's ~250,000 M8s in circulation and a ton of owners riding and enjoying the Hell out of them without major issues, us included. 36,000 miles on wife's and my bike and it's full speed ahead again this Summer with more major long trips scheduled with friends who have M8s without a care in the World about the bikes failing..if they do, it'll be dealt with as best we can

 

Wife's bike is twin cooled or no?

 

Come on guys, did you learn nothing from the evo and fathead years. Harley builds an engine, sees if it runs then sells the bikes to the customer to do the real world testing. When engins go bad they replace them and send the bad ones back to the mother ship for the post mortums to find out what they need to change for the next model year!

 

That's the million-dollar question. We don't know. But he's not the only one. There's another guy here who's gone through three. And on the CVOHarley forum I think there's some guy who's gone through six.

It defies logic. There has to be something specific to these cases that causes this to happen... just has to be. Something different about the particular bike that somehow is affecting sumping (road harmonics? bad oil cooler? Brakes dragging so it's putting unnecessary strain on the engine at all times? I don't know).

The issue also seems related to performance upgrades. Yes, it CAN happen to any M8, but based on the reports we've seen, it seems to happen most to big CVO engines, and to Stage IV. Heatwave had a perfectly running M8 for a while, stock, but once going back to Stage IV it sumped again.

There should be about 250,000 M8s on the road now. Badcooky reported that HD Australia told them that a grand total of 1.2% of bikes had sumped, and that the problem was almost entirely confined to 2017s. We know that it's not exclusive to 2017s. Almost all of the reports are from touring bikes. Most of the reports appear to be from CVO owners, or Stage III/Stage IV owners. So will it happen to all M8s? Theoretically possible, but probable? I wouldn't think so.

For what it's worth, I got concerned enough initially that I put a 4-year Discount ESP warranty on my bike; it was $1000 and kicks in after the factory warranty ends, so six years of coverage. May be a wasted $1000, but then again, maybe not, only time will tell.

 

no, oiled 107
'Twin Cooled' would be nice tho
