Dies and doesnt want to turn over when it hot.....
Hi all, I'm new here. Posted a greeting on the newbie check in.
Tuesday I bought a 1986 vn750 with 20k miles on it. Short ride mostly practicing take offs on Thursday evening, and the same again Saturday morning. Saturday evening I took it out for my first ride for about 35 miles.
The bike seems to be acting like the battery is dead and drained when the bike is hot.
Unless my perception is messing with me over coincidences, the bike does not want to turn over well, if at all. But only when it's hot. It even backfired after yesterday's 35 mile ride when I tried to start it after it had died. After sitting for a couple hours it started turning over and cranking again. I've tried it several more times today. (cold each time) and each time it has turned over and with some finessing of the throttle it does start. It does SEEM to be getting a recharge when it's running or it shouldnt restart after it coos off. It has been a little stubborn to start since I bought it. I have read that is KINDA common with this bike and I'm sure the fact that it's 21 years old probably has a few factors attributing to the stubborn start. It's the problems that seem to come on after it gets hot that are concerning me. I'd hate to ride it somewhere and then break down stranded.
I have a friend who is a moto mechanic but he's aweful busy and has not had time to give the bike a look. Even when/ if he is able to come look at it. I dont want to burden him with a bunch of free labor trying to work on my bike. I'm hopeing he can look at it and recommend a few critical things I should be looking into gettign done. In time I'd like to learn the ins and outs of the bike and do most of the work myself. I have very little mechanical experience but I do somewhat understand the various functions of things like pistons, starters, plugs, tranny ect. I have a willingness and ability to learn. The bike did come with a 1995 edition Clymer service manual (M356)
I have read a lot fo the verses stuff and also threads on what to look for and do with a used 750 purchase as well as first maintainences for the used bike. All around fluid change, check valves, tune up, plugs, wires, battery ect. I have not yet performed any of those used mainainces but I will as funding provides.
Anyone have any idea why the bike seems to act funny sometimes? I have not ruled out that it could be just a weak battery, but I just dont know.
