I feel totally safe with YOU doing that to YOUR bike also. Not a chance in the world of me or anyone else doing that to mine!

I actually bought one of those pucks because I'm **** and so far it's been a messy pain in the ***.
now that I think about it...couldn't I just leave the filter off, put a funnel under the filter housing and wait til clean oil came out if I wanted to be ****?
seems that THOUSANDS of motors have been done the conventional way and run just fine for thousands and thousands of miles, no?

I'm sure if the MOCO thought it necessary to flush the engine, they would have it as part of their routine service schedule and would charge a hefty fee for the flush, and have a "special" flushing fluid designed "especially for Harleys". Evidently, HD doesn't see a need to flush either.
For me, no flush.

It's a lil easier on my softail. With the filter ON the bike I pour a qt in the oil tank, then watch with a flashlight thru the filler hole for the black oil to turn clean. Then drain again. Softies don't hold a lot of oil to begin with, so I like to change most of it.

Maybe I would consider thinning the oil to flush a car that had been neglected for a few years. You know the old woman’s car from next door that hasn’t had an oil change for 10 years and moves once a week to go to church. If I changed the oil and it was black and thick/lumpy I would think about it, but never my Harley. Thinner oil means less lube, less pressure (it runs out of the bearings quicker) and moving parts get closer together. Just plain bad for an engine. The only question is, is it better that or the years of buildup left in the motor? I maintain my ride, no thinning the oil for me.

This is the worst way to attempt to flush you oil system the clean oil leaves the pan then enters the oil pump. it is then pressurized to 35psi it runs past the oil pressure sensor on the front side of the engine then goes directly to the oil filter. From there all vital engine parts are lubricated, if you run the engine with no filter the pressurized oil that is suppose to be going to the engine is not getting there.
