If I understand you correctly...the bike will turn over..the starter is spinning the motor, but it just won't catch? That is correct.
Are you getting any backfires? Have you tried using some ether-type starting fluid? It is backfiring like crazy. No, I have not tried starting fluid
If you are sure you are getting a spark...and are sure fuel is flowing to the carbs... the only reason I can think of that the bike is not even trying to catch , even for a moment or two, is that the mixture is just way off somehow. You are talking about the adjustment bolt on each carb that is covered by the lead cover, right?
AFter you try starting the bike...like 10-15 tries, what do the sparkplugs look like?
They should look pretty wet and smell of gas. Have not removed the plugs since installing them Wednesday night
Do you have a AGM battery btw? Yes, brand new
Are you using the choke to start it? Yes, adjusting it from none to full
If you are saying the bike will not even ignite a chamber, even once, and you are possitive you are getting sparks in both jugs...there is something wrong with the air/fuel mix.
So make sure ALL four spark plugs are sparking...as outlined above, pull them one at a time, re-attatch the wire and hold the metal side firmly to the cylnder head with some kind of insulated plier.
A dark garage helps here in seeing the spark, but it should be visible as a bright blue to white flash.
If they seem fine and are producing a good spark, the only thing left is your fuel mixture. Try starting the bike with no choke, with the throttle opened, with it closed, and then try using some starting fluid.
You should get it to turn over , even if just for a moment with the starting fluid.
Most times, if the bike is running lean, by lean that would mean the fuel/air plug(s) are not screwed out enough, right? you should get at least a backfire. If just too rich, you might have a stuck float, or stuck diaphram.
If your battery is low or undercharged , it might just be too weak of a spark. I have the bike on a Battery Tender and the light was green when I tried cranking last night.
If the bike ran fine before, and you have done nothing to it , other than touch the carbs...I would suspect that is where the problem lies. Do make sure that fuel is flowing to the carbs .........
and that is is fresh. You might have water in the tank? I coastered and relocated the r/r a couple of weekends ago. It was running fine then. It really wasn't until the other morning when I went to leave the house that I noticed it was barely trying to crank her. That afternoon I had to have someone jump me off. Was that a mistake to use a car to jump me off?
