Start Problem

I have a 1992 VN750. I test drove it from somebody selling it locally, and decided to buy it. On the way home, luckily enough, the bike died and hasn't started since. The local garage said that it was the recertifier. They fixed that (after two weeks), then they said it was the starter. Seeing as it was already over 400 dollars for the recertifier, and they wanted another 300 for the starter, I decided to do the starter myself (not a hard job). I got a rebuild kit on ebay, and rebuilt my starter. Still nothing. Got a new battery, a Magna Power, so I couldn't have messed up the charge. Nada...

I decided that maybe my starter was too far gone to rebuild so I'm ordering the part.

If this doesn't work, I was wondering if there is anything else that it may be that anybody could think of. The garage said that they tested the Stator about 5 times because I insisted that that was the original problem, and it tested good each time. The recertifier is new (obviously), and The starter should work. I'll try the new one when it comes in, but I sure don't have a lot of faith that I'm going to get it fixed.

What I'm saying is, should the new starter not work, does anybody have another thought as to what the problem may be?

Welcome to the forum. Could they have said stator rather than starter? Look in the Vulcan Verses for the stator and regulator/rectifier tests. Did you keep the old regulator? I'll bet the garage misdiagnosed it and that one may still be good. Have you checked the battery to be sure it is fully charged and good?

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

Welcome to the Vulcan madness. Sorry about all the trouble you are having.

It might help if we knew the mileage on the bike and its overall condition.
How far did you ride the bike on the test ride and on the way home?
Did it have good power during the ride?
I suggest doing a compession test, then pulling all the plugs and doing a spark test too.

Was it stored inside, or does it have surface rust, etc?
Has it been sitting for a year or more without being ridden?

Here is a link to an online motorcycle repair course that may be of help to you.
Lots of topics to choose from as you need them.

I am not sure from your opening post what the current problem is.
Did the rebuilt starter not spin over at all, or just not have enough power to turn the engine over fast enough to start?

Is the new battery fully charged up?

Give us the answers to these questions and we may be able to give you more help.

So does the bike turn over or not?
I get the impression that it doesn't........
if not, try this:
1. check for 12v at the battery
2. take the right side cover off and follow the fat wire from the positive terminal on the battery to the starter relay. There is another fat wire connected to the relay just below the one from the battery. This wire goes to the starter. Stick a screwdriver blade between the two large posts on the relay...the ones holding the fat wires. Don't touch anything else, like the frame. you should get a healthy spark between the screwdriver blade and posts, and the starter should spin. if not, check the wire from the relay to the starter for continuity. Check that the starter is grounded. If the wiring checks out and you have a good charged battery, then it must be the starter.

Does it have spark?
Are the cylinders getting gas?
Is there good compression?

If yes to all three, it should start.
