Bike not starting

Last summer I replaced the stator and the balance dampers. Everything seems to be bolted on correctly, wires are all connected but the turn signals and the radiator. Bike cranks but that's it. I do get white smoke coming out of the front carb air filter. Emptied the gas tank and the carbs, put fresh gas in and about a half can of sea foam. Also replaced the we plugs and it still isn't turning over. Am I missing something? What are the next steps I need to take to get her running again.

So the bike has been sitting for close to a year I take it. Depending on how bad the carbs are from sitting, just putting seafoam in the tank might not be enough. Gas would have to be flowing through the carbs for the seafoam to work. Maybe there clogged up.
Also have you checked to be sure your getting a good spark from all the plugs?

I have the carbs off now, I'm thinking of taking a closer look at them this weekend. Is there an easy way to test I'm getting spark? I think I checked earlier this week but it seemed really weak, but I was using a spark plug test.

The old fashon way is to remove the plug, hold it against the engine case to ground it turn the engine over and see if the spark plug sparks, should be a nice blue spark.
Have to be carful though, maybe even get someone to help you. You need to insulate yourself. mayby if you can hold the plug against the engine with a wooden dowl. There might even be something you can buy. call your local autoparts store. If youve never been shocked by an engine, it dont feel good.
Should be able to do this with the carbs off, Plus you need to have a good strong battery. Is your battery good? This bike need almost every bit of a good charged battery to start. Also alot of people here swear by the NGK Iridium Spark Plugs. I put them on my bike and so far pleased with the way my bike starts.

I am just going to echo his be careful statement, along with the suggestion for Iridiums. My signature has the part numbers.

I am having the same problem with mine. I swapped to regular grade gas and it doesn't fire. I can roll start it, but to push the button just runs the battery down. If I move the choke while trying to crank it, it backfires. I am waiting for my new iridium spark plugs to get in in a couple of days, we will see then. I have fooled with the stand switch and everything. I just think I have a fowled out spark plug.
Update: I hooked the tender up last night and let it charge all night, woke up this morning and she fired right up. Still can't wait to get those Iridium's in, that will hopefully eliminate the not starting after it's warmed up issue.
