Good job getting the Yuasa. I use them in my bikes & highly recommend them. Every Yuasa I've had has performed well.

On to your issue...
Have you checked all your fuses?
Is the starter switch engaging & retracting fully?
Check your kickstand switch as well.
Is your fuel filter clean?
Is it flooded?

M1ke, the service manual has trouble-shooting procedures that may help you work thru this as well.

 

The starter is engaging and spinning the engine. I can hear a couple of burbles from the exhaust which sounds like it is trying to ignite. I have not checked the fuses nor the kickstand since the starter is engaging but obviously it wouldn't hurt to check.

My first order of business is to check the spark plugs. I haven't replaced them since I purchased the bike but I do already have replacement plugs waiting. I will check to see if they are wet or not and let the cylinders air out a bit in case it might be flooded.

How do I check to see if I am getting spark from each cylinder? On a car I can just pull the plug and touch it to the block while someone else starts the car. Is the procedure the same with the bike?

What really confuses me about this issue is that it was running fine for a few minutes and then all of the sudden it wouldn't restart two seconds later. I've also not had a single mechanical issue for the 600 miles I've ridden it.

 

Yep, the procedure is exactly the same. Pull the plug, put it in the end of the plug wire, get it close to the block and spin her over...just be sure not to get too far away from the block while doing that because the spark will instead ground and therefor, travel into you and believe me..that ALWAYS HURTS and your hand and part of your arm stays numb for a little while after. I've been hit by quite a few spark plug jolts in my day and I have to say, the last time I got hit with the spark from a motorcycle, it hurt worse than getting hit with the spark from an MSD. Come to think of it, that probably has a bit to do with what's wrong with me ROFL.

 

Got it fixed! I had the tank and air box off to get better access to the plugs when I was just looking around and saw the fuel pump connector was unplugged. I finished swapping in the new ngk iridium plugs and all is good. I can't complain too much because now I have some good experience taking the bike apart and also have a brand new battery, brand new plugs, and also a battery charger and bike cover.

A few things I learned:
-ignore the service manual when changing plugs. It is MUCH easier with the tank and air box off and access them from the top.
-when changing plugs, loosen them with a wrench but then use the coil plug to grab it and finish loosening it. Reverse this process for installation.
-its fairly easy to get the tank and air box off quickly. Getting the carbs off for a cleaning shouldn't be bad at all. Even when working on a city sidewalk.
-I need a new air filter and two new smaller filter that are also inside the airbox for the carburetor vents. I'll order those at the same time as my new front fender.


Thanks for the help everyone!

 

Awesome, I'm glad you got it worked out. How's the weather up there now?

 

This week was really nice but it is starting to dip into the 30s at night.

I bought some thermals, a wind proof jacket liner, and some goretex gloves. Im going to ride as long as I can stand it.

 

Glad finally got it going! Congrats on a job well done!

Sounds like u got some good cold gear. Consider getting a heated-grip kit...can really make a dif in cooler climates.

 

That's what I have heard. I'm debating on it right now. When it gets colder I might be more motivated. My first order of business though is to get a new front fender.

I also just randomly came across a complete oem battery tray/undertail on ebay. It has both turn signals, tag light, reflectors, tail light and everything. He even threw in the oem front turn signals and I got it all for $40 shipped. It will be nice to get that tattered and cutup piece off and a nice complete oem piece on there.

 

Great deal!

 

Quick question - the low fuel level sensor, it has two single pin connectors. Does it matter which connector is on which prong? I imagine once the fuel level is low, the sensor just connects the two pins.
