Has anyone installed a drain plug for crankcase on an evo before to get all the oil out?

 

No, we disassemble the engine and clean all the parts in a parts cleaner, that is the only way to get all the oil out.

Seriously... There will only be a few ounces of oil left in the crankcase after the engine runs long enough to scavenge the oil.

 

When I change my oil I hate knowing I'm adding new oil to the **** still in the case.

 

I asked this question awhile back. Was told waste of time. This is what you're looking for and google scavenger and diy scavenger puck and you'll find what you want. But no one here supports it. I wouldn't mind using one right now to flush mine out but I don't have one.

It is a feel good thing.
If it makes you feel good go ahead and do it.
Is it necessary no but what the hell it's your bike.
It damn sure won't hurt anything either.

 

Then you need to strip clean and rebuild it every time you change oil! Alternatively stop worrying about it, drain oil as per the manual, refill ditto and enjoy the ride. If you have only recently bought your bike it has survived this far without any ill effects at all!

 

A few aftermarket case makers have either a plate or drain plug installed. The hard part about putting one in a stock case is getting in located where it will drain, not hit the flywheel, and not cause the cases to crack. Basically it isn't worth the time. You would still have used oil in the lines, top of the cylinder heads and other areas. People have been doing it the regular way since Harley has been around and no real problems have occurred !!!! Hope this helps.

Yeah, no doubt, that's what I do , I think he was making a joke about tearing it down to change the oil !!!!!!!!

 

Maybe there's less oil left behind than I thought , just curious if anyone has made this mod.Doesn't mean it's a bad idea but I will leave well enough alone.I may rebuilt motor next winter is the reason for my question.

 

My current motor has survived for 100,000 miles and counting by changing the oil and filter every 2,500 miles. Would it run longer by scavenging the oil? I don't know.
