Reusable oil filter on M8 ?
#12
Well now that you have heard from the nay sayers, here is some positive input. Yes, I am running a lifetime oil filter on my M8 for almost two years now. It is one of the first things I do to a new bike, I’ve been using them since about 2005. I’m running a PC Racing brand on my bike at this time, but I don’t think there’s a lot of difference between the different makes. I personally think they do as well or better filtering the oil as the disposable ones. So if it is what you want to do go for it.

One of the basic arguments for the PC Racing filter is that it flows more oil than a paper filter when the engine is first started. Also, the filter holes are 30 microns uniform, where paper filter hole sizes vary, so they may have some holes 40-50 microns wide or wider.

OMG...seriously. For normal use and maybe even some racing uses, does it make any sense that Harley would have a filter on a motorcycle that could potential starve an engine of oil? the function of a filter is to keep material out of the engine and that's it. it is not to regulate the rate of flow into the engine (which depends on temperature and viscosity of the oil). If you get a lot of crap in the filter, the filter will be saturated with oil and will flow damn well. keeping the engine clean.... probably not so good. Racing oil filters are designed for much higher rpm engines that need a lot more oil than any Harley. A racing filter on a low RPM Harley engine is designed for one thing only.... to take your hard earned money out of your pocket.

Considering that the PC Racing stainless steel filter is over $100, that's a pretty dumb statement to make.

Do as you wish, your money. I've been dealing with the latest and greatest gizmos for bikes and harleys in particular since the 70's the largest percentage of them added no value and some outright went backwards. I could rattle off a couple dozen very popular aftermarket products that are bunk but the hype lives on and people will pay more for them.

A buddy bought one of the K&P look a likes once, PC 1 I think it was. His bike was on his lift and he had just installed the filter. He thought it snugged up early so he removed it and made sure the filter was in the slots and no extra o-ring was present and I tried it. 1 and a half turns to contact, so about 2 threads installed. No thank you.
