Double oilfilter?
Gents,
More questions...
I've a boxed bike that I'm rebuilding.
It was built around a Shovel engine but has since been fitted with the trusty EVO.
Thing is, that engine has the oilfilter in front of the engine but the oiltank on the bike still has the internal filter of the shovel...
Can I run it with this tank and just leave out the filter or can I run it with the filter in place, effectively having two oilfilters?
Thanks a lot for your opinions again!

If there is a spin-on filter in the return line, you can leave the cartridge filter out of the tank. I ran my shovelhead FLH POS like that. While I don't think two filters would hurt anything, I don't think the cartridge filter in the tank will catch anything the spin-on would miss, short of catastrophic failure that blocked up the spin-on, and by then, catching anything in the tank filter isn't going to matter.

Yes it's a later style EVO engine so ot has the spin-on oilfiltyer mounted in front of the engine!
So basicly, forget about the cartridge filter and use the existing tank then?
Sounds like a plan!

Yeah, just pull the cartridge and forget about it. I don't think they did much anyway. Many people would clean out chunks of metal from the oil tank after grenading a motor, back in the day. All those chunks got past the cartridge filter.

Put 3 or 4 Filters in the return line and see what happens...Hell...Add a couple Coolers too...
You will convince yourself that 1 Filter is Plenty.
These engines don't tolerate restrictions in the return line...

a short lived fad years back had 2 orange fram car oil filters hung on the side of a chopper what ever, and it was short lived as the inside gasket on the oil pump would blow out from the resistance
