Isx cm2250 engine brake choppy

[Ragindirt]

I see that with my 2010 871, Jake's suffer after about 10k plus, and starts making more valve train noise.

Now that being said not wanting to jack this post; can one who is fixing to do an mm, plus roll new bearing flush the engine a few weeks prior to work.

My thought was drain the oil, hook up a small pump to oil pan with a filter, then circulate back through oil filter housing.

What product go use, or if it would even work eludes me. Was thinking that my wife could kick it on once a day for an hour while I am gone, friggen things is nasty inside and I change between 12/15k.
