Not too hard to get the excess oil out. Easiest way is to tip the bike on its side with the oil fill bung out, and drain off some of the excess via there. The only other way to do it is drop the oil entirely and start again with fresh oil(dont reuse it even though it is new). Gets really messy trying to put the sump drain bung back in with oil pouring everywhere. You also stand the risk of getting dirt into the engine, so i Dont recommend draining off the excess from underneath. Dont run the bike with excess oil. The site glass is fitted from the inside of the casing, and is rather hard to clean. They get dirty from a build up of clutch friction material settling on the glass. You have to strip the motor down completely to do that. Hope that helps you solve your problem. Happy to answer any questions you may have. Riding bikes is so much fun...cept when it rains!! regards robotek

IF you have a battery get a new one ; put in new gas ; super; dsid you ajest any screws on carb. You tight need to run a prime tank right to your carb to prime it; and then hook your tank backup new gas lines to your carb. Now break out with the WD40 to spray all switches for rust.

SOURCE: High Idle On Start-up.
Most fuel injected motorcycles do start up in a "fast idle" mode. Although I don't know much about fuel injection on Harleys (H-D will not tell you much about it unles you are one of their technicians), I don't think the system is equipped with an engine temp sensor. Since the crank case sensor get it's pulses from pockets cut into the outer edge of the left side flywheel half, the sensor will have oil on it.

if it has reed valves, check them for either cracked or broken pedals. also try starting it with the air filter removed. also make sure the choke is operating properly

First, you need a good battery. The bike does have electronic ignition. Soak the carbs in denatured alcohol for two hours after removing the float bowls, then clean with spray cleaner. Spray into every large and small hole you can find. Remove the rubber diaphragm from the center of carb prior to cleaning. New diaphragms are $196 each. Check all fuses. Put in new spark plugs, NGK-BP7ES. Clean the air filter. Get a can of spray starter fluid and spray on the air filter. The rubber mounts for the carbs are likely to be a problem once it gets running. It looks like they are still available at Babbitt's, $53 each. If un-carburetored air can get into the joints it will lean the fuel mix and cause uncontrollable high idle.
Before you sink a lot of money into the bike, check for spark. If spark is present, coast the bike down a good sized hill without any spark plugs being installed. Put the bike in 3rd gear as you go downhill then let the clutch out to turn the engine over. Now ( using the clutch lever ), shift through all the gears then neutral. If the bike will not shift properly it likely has a bent shift fork. I can't find any forks avaiable. With a bad tranny I would put it back in the dirt floor building and find a newer bike. Here is a link to Babbitt's. Please rate my answer. Thanks.
