V-Star Stator/pickup coil help

I recently bought my first bike, a 2006 VStar 650 Midnight custom. Really like the bike but already have an issue. The bike has 12k miles but won't start. I've read a lot and have narrowed it down to the pickup coil or CDI but I am a little shakey on electric stuff and multimeters. The book said that the pickup coil should ready 182-222 ohms, my meter is a craftsman automatic and when I hook it up I am getting a constant fluctuation from 1.330 down to .999 Mohms. With all that said is when I turn off the automatic setting and change the reading levels I get 01.90 to 02.80 Mohms and no readings on the 000.0 Mohms setting and no readings on any K setting. I am thinking the fact that the ohm meter never settles is an indication of a bad pickup coil but could use a little advise, any help?

What were the symptoms you had for it not starting? I'm having a similar issue and also trying to narrow down what the problem is.

A few weeks back my 2007 1100 wouldn't start (just a buzzing noise, no engine response) so I replaced the battery. After that the bike started great but later when out riding it stalled 3 times when slowing to a stop... but after pulling over and sitting for a few minutes it would fire up again no problem. Now when I try to start it the engine just won't crank/fire...like maybe a fuel or spark issues.. Is this similar to your problems?

I have the same problem with my multi-tester. It thought it was me or because it was cheap version. I also have the issue of no spark.

Solved my problem with the multimeter. Not getting a good connection. I end up taking the probe and poking through the wire itself (barely poking through) and I got a good read without fluctuation.

Was the reading you got in spec?

If not replacing the PU coil is not too difficult, I've done it numerous times, twice on my own bike. You will need a bike jack or poor mans lift out of a few boards as the kickstand needs to come off and it does help to have a torch to get the PU and stator screws out, without heat the lock tight they use can break the castings.

It's better to take a pair of vice grip to the screws. I had a hard time even with a torch, plus you take a chance of burning the wires and warping aluminum. VG on the sides and they were out in 5 minutes.

If you didnt heat em up first you got lucky, I know several who have broken their cover using vicegrips on those screws then its another 200 bucks for a new one if you can't find one on ebay. Big chunks of aluminum break off so it can't be helicoiled.

I didn't have a torch or heat gun when I did the first one and also tried VG, I got lucky and only broke the screw off and not the casting. I had to take it to someone with a torch to hit em with some heat to get the others out. On others I've done I've just used a heat gun and that works fine.

I wonder what they use on those screws, it is seriously strong stuff!

I watched my bike mechanic do it with VGs when the torch didn't work for me. I've seen the VG method a couple of times on stubborn or head-stripped screws and they always take their time when doing it. Maybe a combo of torch and VG is the best method.
