Looks like my local dealer wasn’t getting the black earth fade CVO I wanted, so I changed my mind and am now going with the burgundy cherry. The thing is I want to change the pipes to black chrome to match the front. Doing a web search and it seems impossible. Any ideas??

That gauge on my 05 banana is as useless as s**t. Needle bounces around like a tach.  >:(

This is accurate to a certain extent with older bikes. But the OP has a 2017 CVO. I’ve had 2 engines fail due to sumping on my 2017 CVO Limited. There was never a drop of oil that came out of the air cleaner. The sumping experience in the M8 is due to a miscalibration between the oil entering the crankcase and the oil being removed from the crankcase due to a defective oil pump and other engine design flaws. It is not an “all of a sudden” event. If you never ride more than 20-30 mins at a time, you'll likely never experience it. In fact you'll mask it because after building up oil in the crankcase, the next time you start the bike and let it idle for abit, it will empty the crankcase during idle. Sumping happens over time but only under certain circumstances such as rapid rpm changes over a period of time during hard riding in the twisties OR traveling longer distances at higher speeds on the highway. The amount of time is variable based on how mis-calibrated the oil flow is.

At first a sumping bike just feels slightly less powerful as it would on a normal hot day. But eventually the oil in the crankcase builds to the point that the crank is sloshing through the oil as it gets deeper in the crankcase. Eventually the crankcase fills leaving massive rotational resistance. Efforts to accelerate are met with...no response.  The engine simply can’t rapidly change rotational speed because of the resistance.

Engine failure comes from there being so much oil build up in the crankcase, that the pan is starved leaving no oil to be pumped to the top end. The engine also overheats just from all the resistance of too much oil in the crankcase. The engine begins to overheat and components such as bearings, lifters and worse begin to fail. The rider will never see an oil light which is quite disturbing as a significant design flaw in my opinion.

If you suspect sumping in an M8 engine, you should immediately read the latest version (there are 7 versions) of HD's Service Bulletin 1450 (attached below)

I hope that helps
I have never seen this and thank you I think I am going to make a change!

We got our Cherokee with V6, 9 speed auto, 4 wheel drive, lockers, armor, leather, gps, 9 speaker stereo...for 32K. Ok, I knocked the exhaust system off once, but driver error.  :P

Great price .. just need a body that fits in that car :)  Even the GRAND Cherokee is a minor struggle.
