Okay, Thank you for your excellent responses and clear answers underlined. Well done.
1: Are you holding the start button for more than 5 seconds max? (You should not be.) Y/N *Not really, but sometimes longer then 2 seconds, or I have to press it multiple times.* *Please warm the bike up with the choke on full for a minute, then restart the bike as normal.* 2. Does the bike have trouble starting (Hence over use of the start button) Y/N *Sometimes - usually after stnading for more then 2 days at a time.Get an AGM battery and a trickle charger. The nighthawk is a poor electrical design and only CHARGES your battery above 2500 rpms. IT takes 30 minutes of riding to recharge a low battery. This means your battery is shot and isn't absorbing a charge when it rides, probably due to a dead cell. Batteries for this bike only cost between 40 and 80 USD, so I got an AGM at Walmart and it just fits into the compartment. I don't use the swingarm to bolt it in place, because it won't move. It's snug there. Battery has gotten low once or twice but I just top it off on the trickle charger. I ride mine once a day for ten minutes minimum to prevent fuel clogging the idle jets.* 3. Are you sure the timing and valves are all operating correctly? Y/N *Not sure - never worked on or checked either.* *It isn't the scariest procedure to do, but eventually to be sure it isn't an issue you should learn to open the top end cover, and learn the procedure to bleed the hydraulic valves. It's not difficult. VIDEO below* https://www.youtube.com/watch?v=YxRJeqr_5xY 4. Are you sure the springs on the brushes are not adjusted too tight? Y/N *The set I had ordered doe not seem to have any adjusters on the springs.

Five second is the maximum.* 5. Is your carb completely clean and particle free? Y/N* I had cleaned them last autumn and synced them up in May (to the best of my abilities, which are not all that...)* * A NIGHTHAWK is an old quad aspirated carburetor system. They require being cleaned probably twice a year if they aren't ridden daily. To remove them, pull back the airbox by unbolting the FENDER OVER THE REAR TIRE made of black plastic, and airbox from frame. Loosen the metal belts around the carb boots, intake and exhaust both. Now that it's all loosened, pour boiling water from a thermos over the rubber boots, front and back. This makes them soften for about 60 seconds, long enough to pull them off the back of the carbs, facing the rear tire. Repeat the boiling water onto the front boots next, and pull backwards on the carbs to free them. Rotate the carbs sideways, out and flip them over, on the left side of the bike (clutch lever side)The cables can be loosened, the carb can be put on a bench, and you can one by one take off the bowls, unscrew the jets, and unclog them with spray cleaner. The idle jet is the one that clogs, every single time, due to additives like ethanol in modern fuel. Once you clean the idle jets, you want to spray out all the inner passages on the carbs, and then reassemble the carb. You probably don't need to do anything to the float needles. If you did the bike would flood and not start. * *Each of these steps is a step we learn as we trouble shoot our own bikes. You should now learn to 1. Diagnose your running bike for volts produced at idle and above 3000 rmps. You'll need a cheap voltmeter to do this.2. You might want to get some starter fluid to spray into the intake under the seat if your bike starts poorly to save your starter brushes on cold days.3. You'll need to learn carb cleaning as it's much cheaper and easier and enjoyable to this yourself. 4. Consider this: The nighthawk was engineered to be a daily driver bike. So the battery is not well charged by the bike system alone. A well built trickle charger can be put on the battery to top it off over nights in winter.
