My Yamaha Vstar 1100 Custom Won't Start. What Can Be The Problem?

Try your ignition control, these are prone to failure on the Yamaha cruisers. Also test the main cable connection between the CDI and fuse box. If this is loose it will effect starting. Try those first off, also check security of fuses. Also look at the battery, if maintenance free, it should read around 12.5 amps. If it requires maintenance check the fluid levels, if necessary top up with DISTILLED water. If that fails, check the connection of the starter assembly on the handlebars and work back, cleaning all connector as your go with WD40 or similar. If all that fails check HT lead connection, alternator/starter motor connections with a circuit tester. If this fails to rectify the fault you may need a new Rectifier, easy enough to find on ebay.

Hope this is of help.

There are many things that can be wrong with it. To trouble -shoot the bike first, remove the spark plug from the cylinder head, when removed attach the plug to the lead, put the plug agaisnst the engine case, try and start the bike and check for a spark. If there is a spark check that there is fuel going through to allow spontanious combustion.if it has all these factors check the interlocks to make sure your not just stupid. If non of these are a problem it may be siezed.
