How many sexual positions do you know? Which one is the best?

 

I tried RL Tranny this time around and is does seem to quiet down shifts and can get natural easier. Some old timers would do an oil change. Dump the oil out put the plug back in pour Kerosene into the block run the engine drain the Kerosene and refill with the new oil.

 

Hope you don't ride in public like that.

 

oil is oil, harley buys it and puts their name on it. please don't tell me you think refines their own oil. are people really that freakin dumb

 

Think you misquoted old timers and what they did. You should have put in idiots.

 

As long as it's changed regularly, get whatever is cheapest.

 

I don't claim to be an expert, I defer to people much smarter than I, who have taught me the following about twin cam "sumping":

There are two sumping conditions.

Wet sumping, means more oil is pumped into the engine than is scavenged back into the oil bag. This is a bad condition that should be fixed ASAP. This is usually cause by a pinched/bad o-ring at the scavenge port where the cam plate and crankcase meet. This will occur when the engine is running and will rob HP, up to 20-30HP. The bike will run sluggish.

The other type of sumping is from a worn oil pump. The oil will flow back through the oil pump into the sump over time when the engine is shut down. It could be days, weeks, or months, depending on your oil pump. That is why you should always check the oil level when warm to avoid overfilling. The oil will usually pump back into the oil bag within the first few minutes of being started. Not a major problem, but not right and will get worse.

These are dry sump engines, when working properly, there should never be more than 4 to 6oz of oil in the sump.

There should never be enough oil in the sump to where the flywheels touch oil.


Not sure how all this relates to your pic, but most experts agree there shouldn't be more than 4 - 6oz of oil in the sump if all is working as designed....

Again, this how I was schooled when I inquired about twin cam sumping..... I don't have enough time/experience working tearing down these engines to claim any first hand experience.

The other forum I read, HTT, is frequented by people who run shops and work on these motors everyday. I searched that forum before posting this, and found plenty of similar expalnantions to what I was taught about sumping....

FWIW.....

 

Just read the Harley-Davidson(R) Motor Company Service Manual Engine Chapter Engine Oil Flow. That is all I am quoting. The amount is what I have seen. You may be correct that since the return pump is larger then the pressure pump side, on the crank side, the sling oil is just the dump that the crank picks up. However, the only way the oil on the cam side can get to the return is thru the bearing openings on the crank. So that side runs pretty deep. The crank side just may accumulate the 6 oz you refer to at shutdown from drain down but the pump cannot suck the oil below that lip in the case. On a Softail, the actual sealed drain is in the cam side and that is what I am familiar with.

 

There are other forums?

 

Bwahaha...

1) It says in the MoCo's Koran that you smite Willie Allah G. if you don't use his sacred oil.
2) Hillary emailed she uses HD, Trump combs over Mobil 1 daily.
3) HD oils = .380 Mobil 1= .45
4) Nah, too easy and I don't want to get banned!

Mobil 1 V-Twin for me. I'm too pissed off at my "made in China" MoCo boots and accessories that are falling apart to assume that their oil isn't watered down Chinese Vasoline!!!
