Who changes there own oil, did mine the other day. Did it as it says in the book and thought it was strange that you only drain the oil from the oil tank, there's no actual drain in the crankcase. Says in the manual not to add more than 3.3 litres when refilling but i think this is for total engine rebuild. I only took 2.25 litres out so was thinkin there must be another litre floating round in there some where. Rang the dealer just to make sure and he said they never add more than 2.8 litre after an oil change which is approx what i added when refilling. Any way just thought it was odd that there is no crankcase drain, oh and dont try doing this without the proper filter wrench from HD, no way you can get that filter off by hand, just no room to get hold of the thing. dealer also told me he had a customer try and undo the grubscrew in the bottom of the crankcase as he thought this was a drain, he cracked the case while doing this and cost him $2500 to get it repaired, cheap oil change hey
HD's run a Dry Sump, there is a scavenge section of the oil pump, it's purpose is to pump the oil from the crankcase back to the oil tank (oil bag). There is always going to be 100 mls or so in the crankcase with the engine stopped, more if you let it idle on the sidestand before you shut it down. Then there's the oil left in the external lines, internal galleries and the oil pump and what's in the filter that spills when you remove it.
Remember always underfill when doing an oil change, ride the bike bring it to operating temperature and then check the oil level before adding the last 1/2 to 3/4 of a litre. If you over fill it has to go somewhere and that place is usually down the side of the bike when it pops the oil tank cap off or spews out through the air cleaner.
thanks for that fatboy, i was thinking maybe they ran a dry sump so thats good you confirmed my suspicion.
Guess he has it sorted by now......it was 11 yrs ago that post
Ahh, but does he check the oil with the dipstick on the stand or upright
Prob a stupid Question but why get a Scavenger kit? what does it do??
Lets you get most of the old oil out on an oil change, I have one, on my softy it pumps out about 700-800ml of dirty oil before it's clear, needed? Maybe not but I like it.
oh yeah sweet, im looking to install a oil cooler, would it scavenge out of there also?
+1 on this Hilly, cant beat the scavenger. Yes also works with oil coolers shreko. Have a look at the Rougue chopper web site. They are not very expensive
Be a short ride, give it a go and report back.....with pics
I look at it like wiping your arse properly, better to get as much shit off as you can.
