The rest of it consists of the solenoid, linkage, etc that sits on top of the head. If the decomp is stuck (always engaged), your compression would be really crappy. I don't even know if it would run.

I do not know if this is the problem. I am not saying it is, I was asking for guidance and what does this unit do?

What I was trying to convey was that this is the only thing I moved when I was cleaning the bike (under the tank)

I just detached it from the tab, and put it back.

Here is mine:

What it does is fire the decomp solenoid (for about 1/2 second) when you start the bike. That solenoid opens the exhaust valve so the piston can go to TDC on the compression stroke with less resistance (no compression). That allows the starter to spin it past that point and get some momentum going. Then the solenoid goes back to a rest state, the exhaust valve will be closed on the next compression stroke.
IF the decomp solenoid was stuck, or the controller kept it always fired, or the link was not adjusted right, the exhaust valve would always be partially open. Not a good thing.

Trying to troubleshoot and traceback my steps when I cleaned the bike. What did I touch that screwed up the iddle? it was runing fine until then

What I would do:
Turn petcock to ON.. make sure there is gas in the float bowl.
Turn petcock OFF and pull the tank.
Check all connectors.
Start the bike (leave the tank OFF THE BIKE). Wiggle connectors and wires to see if the problem might be electrical. You have enough gas in the bowl to go a while like that.
My gut suspicion is the high voltage line to the spark plug. Make sure it is seated well on the plug. Move it away from anything else as much as you can (in case it has a crack and is jumping to ground)... and watch out touching it with the bike running. Shocked

Being there, done that. I did that last evening. The plug is seated well. I wiggle the cables while it was running to see if the idle change but, no luck.

It has to be something simple, just cannot figure out “what”. If you read my original posting you can see I was doing great, running smooth and strong. I just wanted to clean the darn bike…

The bike look nice! It’s all clean Undecided

Might be just coincidence. If you haven't already checked, I think you ought to pull the spark plug out and take a look at the electrode. Or even just replace it and see what happens.

I know. I’ve already taken the carb a part (again) and cleaned it. Changed the fuel on the tank also. Still runs the same (no change)

Even if it's not the problem, you need to eliminate the simple things before you go ripping stuff apart.

Guess what my friend?

I do not understand why but, I changed the plug and VIOLA!!! Got my monster back!!!
And just to ensure it was the plug, I put the old plug back and it ran like crap again.

Now, can anybody here explain to me what the heck happened?

This was the original plug the bike came with and the bike just turned 2000 miles last weekend so, “theoretically” the plug is new, correct?

I am a logical person; I am not a "just because person". Things happened for a reason there is always a cause and effects. Why or what was the cause for the plug to fail?

Attached is a picture of the old plug and the new plug. The gap in both plus was the same, it looks different because of the angle of the photo.

Thanks ”old man” Wink

, you were correct

Qwapy,
Glad you're runnin' again. I agree that a plug should last more than 2000 miles but the fact is sometimes they don't. And you can't always tell by just looking at them that they aren't any good. The ignition system in these bikes is pretty primitive by todays standards and we're dealing with a one cylinder engine after all. Without a good hot spark a motor like ours just won't run right. From the picture, the plug you took out looks kind of dark to me. Might be an indication that you are running a little rich. The insulator around the center electrode should ideally be a light tan color and should not have any evidence of being wet.

The owners manual reccomends replacing the plug every 7500 miles. That's a really short interval nowadays. I think Suzuki is admitting by that interval that the ignition system isn't all that great.
