I hate to tell you this but, if the bike sat for a year with gas in it after the carb work, it'll likely need another carb cleaning. Crying or Very sad Over time, gas in the carbs turns to varnish and gum which clogs up the passages. What makes you think the starter is not working right, Kar? Does it sound funny, or what? About the compression test, you'll need a compression gauge - most automotive parts retailers have them. It's a small gauge with a flexible hose that you screw into the spark plug hole.

IT sounds like it is the pickups not working (.telling it to spark) if not then it will be CDI UNIT OR ENGINE GENERATOR COILS

1. #1 test. Obtain a 12 volt circuit tester, the type that looks like an ice pick with a wire coming out of the handle. With ignition on, hold the tip of the circuit test against the post of the coil, the post that is marked with a + The light in the tester should light up, meaning you have battery power. If you don't have electrical power there, trace back to battery to find out why. If you do have power at that point
2. Moving the the opposite side of the coil and place the tip of the tester again the post marked with a minus. With the key on, crank the engine. The light in the tester should flash. These 2 test have just tested your battery and ignition system. Bill

First you'll need to get a jet kit from West coast star. Then you'll need to jet the carbs to run equally. This may take some trial and error. Another thing that worked on my bike was the upgraded coil kit they sell. It's almost double the voltage of the stock coils and comes with better insulated wires for a more uniform resistance. I haven't had this problem since. It'll make the cylinders fire evenly and save you from those pestiferous fouled plugs. I hope this helps.

Every component plays a part in the ignition system. Check the wiring as you go. Start at one end and move forward. You have done a lot of work so far. so you should be close. If the igniter is fine and the other components too. Then it would narrow it down to an electrical problem or no signal/pulse to the coil. See if the coil is receiving that pulse. you can use a test light for this test. Pos. will be power and NEG. will be the pulse. With light on the NEG. crank the engine over and see if it flashes. Let me know how its going.
