I was having the same issue with my 85 700s, updated to a sealed battery at batteries plus and starts like a dream. Never would have thought that such a small upgrade would have made such a big diference. Battery was almost $90 so twice the price of a traditional but worth the money and has 2 year guaruntee.

Mine is an 82 650 Nighthawk. If I'm using the bike as a commuter, it starts immediately first thing every morning and coming home in the evening. I'm OK if I stop for gas right away but if I drive for over 30 minutes and then stop, I can almost guarantee a problem starting. Everything lights up when I turn the key to the run position but it dims like a dead battery and will not turn over when I hit the starter. No power. If I wait 30' to an hour it usually will start, but barely, like the battery has just enough power to start. If I can wait overnight, I can guarantee it will start immediately. Last night on my ride home I had to stop at Sears, coming out no chance. The parking lot has a good slope but it took 3 tries walking the bike up and then popping the clutch in 2nd riding the slope to get it to start. Once started it was fine the rest of the way home. When I got home I turned it off, gave it a couple minutes and tried starting it. It was dead. This morning it started as well as it did back 32 years ago. The battery is 2 years old and I have a new one I will put in over the weekend but I know the new battery is masking whatever my problem is. I would dearly love an explanation as to what is happening. Thanks to all and have a great holiday.

I really leaning towards the starter drawing too much currant when it's heat soaked. Reason being the dash lights dim (almost flash as the starter pulls threw each compression) and it has that hit to it.

My 700S starts fine cold, but when hot, can be a real bear to start. About half the time, it starts right away and purrs. Last night, I got stuck and it took over 45 minutes of cranking and letting it rest. I was in Miami, and it backfired like a gun! (You can imagine the reactions!). While turning over, it sometimes sounds like it is firing but almost more like a detonation. Not the mis-timed damaging type, but one "hit" but no joy. Then, one of the times I try it, (ok, obviously the last time) it goes like there was never a problem. Fires and purrs. > > I have new plugs, clean filter, good gas. I have run three bottles of Seafoam through. I was thinking might be a little rich, but not so much now. Vapor lock, as I understand, is not a carb, side draft issue. Possibly the choke plungers aren't going fully in when choke is turned off. Other guess would be dirty carbs. I plan to spray the intake boots with carb cleaner today and check them. What do you think? Would high float level(s) cause this? Could the coils and or wires be heat sensitive? (Due to age). Other thoughts? Bear in mind I have very few tools with me since I live in SC and bike is in Miami, where I work. > > -- > You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group. > To unsubscribe from this group and stop receiving emails from it, send an email to [email protected] <javascript:> . > To post to this group, send email to [email protected] <javascript:> . > Visit this group at http://groups.google.com/group/nighthawk_lovers <http://groups.google.com/group/nighthawk_lovers> . > For more options, visit https://groups.google.com/d/optout <https://groups.google.com/d/optout> . -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
