The V-star 1100, much like most Japanese motorcycles, uses engine oil to lubricate the transmission. (The engine and transmission share the same case and lubricant.) Therefore, checking the engine oil and trans oil are one and the same. There is a window that you look in when the bike is standing up straight.The final drive (drive shaft at the rear wheel) takes Hypoid gear oil, and should be filled to the bottom of the threads on the fill plug.
As part of basic motorcycle maintenance, you are obliged to check engine oil levels of your machine to keep it in perfect running order. This process is simple, quick and might warn you of a problem early. For more information check,

Hi Michael - definitely could be. Do you have access to/familiar with a multi-meter for electrical testing? For the basics - a $15 multim from anywhere will do. There's a few standard diagnostic steps I can walk you through to get a general idea of what's going on. There are numerous things that can prevent you from getting fire to those plugs. I know this isn't the most interesting task - but the first thing you should do is get your seat and as much of the plastics as possible off - and go from wire to wire checking your connections. Grounds, everything. GIve everything a good look over. You wouldn't believe how many times I've seen this type of situation be simply a loose ground wire - or a break in a wire/melted wire - you name it. If you can let me know about the multi-meter and give that thing a good walk around - tug, poke, move around - don't be hesitant. If something comes disconnected or a wire breaks, comes out of a connector, etc. - all the better. It was going to do that eventually anyways. It's a good way to get familiar with the machine and to at least eliminate the simplest causes first. All The Best - and Good Luck - Justin McCartney 17 South Industries, LLC
