Replaced stator, now bike won't start

Agreed. I think the problem was reading the WRONG factory manual. Good thing I didn't do anything much more than look. If only I had just left it alone I'd have been fine.

The only mod I've done is relocate the R/R up front and run its ground directly to the battery

I'd say the moral is if it ain't broke don't fix it.

Well those two things are probably in combination worse than what you needed to do. Are you using 10 awg wire at least?

Longer wires between the battery and the R/R makes the voltage drop higher(probably 4:1).
Connecting the R/R(-) to the battery(-) makes the voltage drops higher(probably 3:1).

So figure your expected voltage drops are 10 times worse (assuming 14 awg wire) than what they could have been. With 10 awg you could have limited that to perhaps 2-3:1 increase.

I assume you never measured your voltage drops , so most of this you would not be aware of.

Looking back did did you do a SH-775? or stuck another SHUNT R/R in?

I used 10 awg. It'd be easy enough to relocate it back under the battery box.

It was from a totaled 82 GS 850 wrecked with 1000 miles on the clock. Maybe to be on the safe side I'd be better off getting a new one and putting it in the stock location.

The predominate reason that stators fail is because of the way the SHUNT R/R design.

The predominate reason you need to cool your R/R by mounting it up front is because it a SHUNT R/R and it is going to kill your stator.

If you get a SERIES R/R, you would have much lower possibility of a failed stator, cooler running R/R and lower voltage drops and better charging all with the R/R in the stock location and not having to oversize beyond 14 and 16 awg wires.

There are links in my signature if your want to read about it.

So, after reading some of your post, you're basically telling me that my current shunting R/R will probably fry my new stator.

yes.....................

When I put my third stator in, I decided to opt for the series r/r route. I've had no charging issues since. I run with onboard voltmeter to monitor output at all times as further insurance.

OK, just ordered the Compufire 55402. Thanks for all your help.

I don't think you will be disappointed. Just follow the Single Point Grounding recommendations and power to the "T" which means cleaning out all your connections using naval jelly(for cleaning grunge) and Deoxit (for leaving a protective coating) or the equivalent.

Will do, thanks again.

By the way, the new R/R probably won't get to me until next Monday. Should I not ride until I replace it or what?

This is an Electroscope stator after 250 miles hard ride using a MOSFET (SHUNT) R/R. You can see the discoloration. After putting the Compufire (and a subsequent stator replacement) in that stopped.

20-30 miles is not going to hurt much probably but personally why stress it if you don't need to.

"20-30 miles is not going to hurt much probably but personally why stress it if you don't need to."

Why? It's almost 90 degrees here in Maine, and the rest of week looks similar-The road calls! I got stuck in traffic today and could smell the gas vaporing out of tank as I sat in sun ,but charging was stabil

You have a series R/R you are allowed to go

I got my Compufire R/R yesterday, installed it today following Jim's guidance and tested the charging according to The Quick Test and it was a steady 14.5 v at 5000 rpm. Took it for a short test ride and everything seemed fine. Tested charging again - same results. Then went for a quick 30 mile power ride on the highway and the bike ran great, maybe the best it has since I've had it.

The full carb cleaning 5 years ago made a huge difference, but with the new stator and series R/R with the SPG it's really performing well. It seems more powerful, more responsive, and runs smoother. Sure, I hoped the recent work would resolvd my charging issues, but I didn't expect such a difference in performance.

Now if I can only figure out the problem with my GSX1100G I'll be all set.

Thanks again for the help.

glad it is working , do you think you cleaned anything that would have improved voltage to the coils? That would make it run better.
