- August 27, 2014, 18:33:45 PMOK, then, so no injection, or no fuel. You said you heard the pump run, so now we're looking for a different problem. Do you have any engine starting fluid (ether)?
If you do, put the plugs back in and give it a spray right down the throttle bore with it open, then close it and see if it will run for a second or so....I'm going to look at wiring diagrams to see if there are any other things that could have been damaged with the backwards battery connection...I'll get back to you real soon...

- August 26, 2014, 18:18:45 PMLet's start with a few simple checks. This is not a very complicated system, at least by car standards, so it should be pretty easy to nail it down. First, take off the r/s air box cover. Inside you will see the throttle body and the two cold idle air bleed solenoids. Hold the throttle open with one hand and shine a flashlight down the bore. You will see where the injectors spray fuel. Remove one spark plug from each cylinder...doesn't matter which ones, just so you have two of the 4 out. With someone holding the throttle open so you can look into the bore, shine the flashlight and crank the engine and see if you see fuel spray. Alternatively, you could stick your finger or a long piece of cardboard in the see if it gets wet with fuel. If it does, then you have just checked the injection system. The ignition system is completely independent of the injection, and is essentially the same as on a carbed engine. Hold a spark plug with the wire connected to the terminal against the engine...somewhere it's NOT painted, and look for a spark at the plug. If you have fuel spray and spark, then the bike is ok, and maybe the fuel you're trying to burn won't. A couple of months of sitting with the crap they call gasoline, now a days is enough to turn it into varnish....Post the results when you can. I'm really thinking it's still flooded.

- August 26, 2014, 16:35:45 PMwhat do you mean incomplete combustion and how do i fix it? is it time for a mechanic to look at it?

- August 26, 2014, 16:28:07 PMSooty means there is incomplete combustion. Damn, I wish I could lay hands on this bike....

- August 26, 2014, 15:02:06 PMIf the EFI light goes out after a few seconds, then it's ok. Were the plugs you took out wet/black/sooty? If the sensor triggers, the EFI light will blink until the ign. is cycled off-on....

- August 25, 2014, 11:11:00 AMMine has flooded twice on me over the years; both times, the battery was a bit low from sitting. I pulled the plugs for an hour to let the cylinders air out, and charged the battery at the same time; left plugs out and charger on for an hour minimum.
Also, since you have been trying for quite a while, and if it has been flooding the whole while, you may need to change the oil, as it could be contaminated and thinned by the gas seeping past the rings. This won't be a starting issue, but is something to think about when you do get it running.

- August 25, 2014, 09:29:17 AMOkay, start simple...
1) bike has been sitting for a while... check the FUEL!, Check the Vehicle down sensor, check the kickstand switch and the clutch switch. Carefully go through your routine start procedure, neutral, kill switch on, ignition in right position, etc.2) Since you are unsure what fuses go to what... check ALL the fuses. (Get a service manual). You may have popped more than one component.
3) Check the plugs and make sure you are getting fuel - after you try to start, pull a plug and check if there is fuel present on the plug tip.
NO = pull plug on opposite side and check, if still no check the fuel pump.
YES = Check Spark.
4) Check to ensure you have good spark... (look up how to check for spark)
NO = If you don't it could be bad plugs, wires or ECU. You will need to perform an ECU self-diagnostic, replace plugs and wires.
= Check the vehicle down sensor!
YES = could be compression problem... not likely in this case.
5) The ECU self-diagnostic will test the pickup coils, injectors, etc.

- August 25, 2014, 09:21:38 AMPull out one of the plugs and look to see if it's wet. If there was a lot of fuel in the cylinders, it could have wet the new plugs. I always crank a flooded engine withe plugs out and the throttle wide open for a few seconds to expel any unburned fuel before putting new plugs. Sometimes I forget that not everybody has been doing the for 40 years...
