I posted this on Yahoo, but thought I might solicit other opinions(Ideas) here.

my 2004 vulcan750 with almost 3,000 miles on it has started to be hard to start in the morning if it has sat idle for a day or two. Once it starts it runs fine.

3 months ago I purchased a mf battery as a precaution. people seem to feel the problem is most likely that I do not have a battery tender on my bike. I commute 25 miles each way to work on my bike, sometimes on the interstate sometimes on back roads...........wouldn't that be enough to completely charge the batt if all is working correctly?

I took the van to work today and have a charger on my battery, how do I check it out with a multimeter? I went to the web and got a chart of tests to do.....any ideas are welcomed

by the way I am 3 weeks out of warranty

If you have a new MF battery, you shouldn't need a battery tender to keep it charged for two days of idling.

Your commute is plenty long enough to charge the battery.

At this point it is time to play detective.
Does putting it on the charger make a difference on how it starts when it sits?
If not your battery and charging system are probably okay. If it does make a difference then your battery may be defective, your R/R might be going bad or something as simple as a bad ground connection. That is when you will need to get the multimeter out.

Have you checked your plugs? Fouled plugs may make a cold engine start harder.

Have you changed your oil recently? I seem to recall someone saying that higher oil viscosity(from a change in weight or older oil) can make the engine harder to start when it is cold.

The good news is that you can start it. My uneducated guess is that you have a fine tuning issue and not signs of some major problem.

Re: Hard Starting-fixed

I checked the bike out last night, and I think it is fixed. went to charge the battery and it showed full charge. at 1200 rpm I got 13.6volts and at 4500 rpm I got 14.8 volts.........this leads me to believe the charging system is working fine.

turn off the garage lights and I notice one plug wire is arcing against something, so I tape it and the arcing stops.....bike is idling better but not great so I pull the plugs........3 are tan, the one with the arc ing wire is black. I clean it and reinstall it.

I began to check the connections and such and I notice a connector just about ready to separate, it is on the left hand top rail of the frame near the fuel tank. I reconnected it and noticed the wires looked pinched where the seat mounts(anyone know if this connector goes to the ignition switch?)
I re-route the wires and fire it up...........she ran GREAT!

thanks for the help...Stan

Good thing to know, now I'll check all my plug wires. I'm about due for a tune up anyway.
