Of course). There is nothing mentioned of this in the service manual. The workshop manual says 'clean' when you are reassembling the engine after a complete teardown. I don't do that very often . There's no risk things fall apart when loosing the cover?Yes just undo the plug on the side near gear selector. Be careful with screen as it is plastic and has o-rings to seal it. Clean with degreaser works best I feel. Reassemble putting screen fully in first then carefully screwing plug back in.,

I need to know the proper tuning of ucal mikuni carburetor with mixture adjusting screw on bottom of cabr (beneath float bowl), an idle adjust screw and pilot screw (hopefully pilot fuel screw since s


Why did you need to clean the carb? Routine servicing of the aircleaner would keep the carb clean for life. The pilot screw should be 1.5 turns out approx. with a small adjustment either way. Idle speed is set to a smooth low idle.If this doesn't fix it have you got something in the carb not replaced correctly? The float needle/float assy? How did you clean it? Have you introduced fluff/dirt into the carb and did you blow it clean with an airline?

Well, just like in a car engine, there is no way to change out all of the oil. There's going to be some pockets of oil left somewhere in the engine. I've torn down engines that haven't been run in twenty years and found pockets of oil sitting in the heads and places like that. If you've changed the oil several times, you should be good to go. Did you check the primary case oil? I've seen the gasoline get in there as well. Drain it and add a quart of oil and you'll be fine.

Good Luck

Where do i find the plug to drain and chang the oil for a 2001 dyana super glide?


The oil tank is on the bottom of the transmission. The oil drain plug is the plug closest to the front left of the tank. Just loosen it up and allow just a drop to come out to make sure you've got the oil drain and not the transmission drain which is under there as well. The oil should be black while the trans fluid will be more clean looking usually. If you drain the transmission, refill with 20-24 ounces of H-D Syn3 20W50 engine oil, H-D Primary and Transmission lube, or a suitable substitute.

Good Luck

I have (2) questions. 1 is the dip stick on my S&S 107" Big Dog. It has two notches/grooves. (1) is at the bottom of the stick, and (1) is at the top towards the rubber cap. Are those the add...


Well, I don't know about a Big Dog but I do know how the dipstick on a Harley is set up. You have two marks on the stick. The top mark is "FULL HOT" and the lower mark is "FULL COLD". Since the S&S engine is just like a Harley engine in that it is a dry sump type engine. When you check the oil when the engine is cold, as long as the oil is touching the dipstick, you should be OK to ride. Once the engine comes up to temp, then check the oil and bring it close to the top mark. Do not overfill. Never add oil to a cold engine unless you cannot see oil on the stick.

Now, for the leak on the left side of your bike. Now you said that your Big Dog is a custom chopper and your replaced the main seal. You did not tell me whether your primary drive is a standard chain drive primary or an open belt drive as so many "custom choppers" run. If you replaced the main seal, did you lubricate the inside lip of the seal before you installed it. If not, when the engine starts up, the friction will burn up the lip of the seal before the oil gets to it. It only takes a half second to burn the lip of the seal. Always put oil or light grease on the seal lips when you install a seal.

If your primary drive is a standard chain type, the leak could be a bad engine to primary O-ring that goes between the engine and the inner primary cover.

Another place that the oil could be coming from is the nosecone. If the oil is leaking out of the bottom of the nosecone, it can leak down to the centerline of the cases. When you put your bike on the kickstand, the oil will then run across to the left side and drip off. The best way to find the leak is to clean everything off as clean as you can get it. Then go for a short ride and come back and look for the leak.

I hope this helps.

Possibly carb issue. Check idle mixture screw, try opening screw when engine is hot and running otherwise, disassemble and clean carburetor.

Engine shuts off when rolling the throttle


They could be related - but what you need to do is first clean out the oil that has collected in the air filter housing - and replace the air filter. Then, clean the oil from the engine - Simple Green and an old tooth brush works great for this. Wash the engine and surrounding areas with soap and water.
Now, with things cleaned off, you'll be able to tell where the oil is coming from after a short test ride. It could be that the oil you saw near the head gasket was actually running from the air box. Hopefully, a new air filter will cure the problems you had with low power and poor throttle response.
