Bad Voltage Regulator ...OR?

[cr0ft]

So what's the story on this and trying to wedge the larger replacement unit in where the original is on the Touring? I have a lot of other crud under both side panels as it stands so this operation wouldn't really work for me. Well, I suppose I could relocate everything but...

@cr0ft This should be right up your alley. If you click on the link "SH847" in my signature (by the way, would be good for you to update your profile to add the year of your bike, please), you'll see the beautiful description by @DEcosse of how the design of the Rocket electrics has the stator working at full capacity all the time independent of need, and uses a shunt R/R that taps the energy as needed for operation and charging, and so on. In that thread, you can see a thermal image made of a bike running with that design. The newer design is a series R/R, and it only draws from the stator what is needed.

The idea here, is with a relatively cheap and straightforward mod, one can place less stress on a part that requires the whole bike to be taken apart to get to, and with your sentiment (which I share) of being buried with your bike, you might actually care (and I know you do) about the long term health of the bike.

Have fun !

And if you can't put it under the left side cover, it would just be a matter of extending the large gauge wires for the current R/R to wherever is your new chosen location -- and I know you know how to do that too.

Yeah, and since I've reduced the electrical use on my bike a fair bit by replacing literally anything that makes light with LED, the regulator is no doubt working harder as well, so putting in a better part than Triumph's cheapo would probably be the way to go. I guess. Going to have to look into it in the off season, which (sadly) is barreling down on me way too quickly. And I didn't even get to go on my planned Norway trip because reasons. Blah.

For what it is worth. the evap system is designed to catch overflow of gas from the tank if u remove evap tank and have the open hose (tank must be vented) u would not want to have gas dumping over a hot motor. in other words watch where the hose points!

I'm sure that was tongue in cheek but just to clarify, the OEM is actually a VERY good part as far as SHUNT regulators go - in fact I would say it is probably the best Shunt R/R you can get.
Series Regulators, although the technology itself is not really new, are pretty recent addition to Motorcycles - in fact the Suzuki DL1000 is the ONLY production motorcycle of which I'm aware that actually utilizes a Series R/R as OEM
(not counting Polaris vehicles which use one)

In this case, we are not worried about the R/R itself from a reliability standpoint, but the effect on the stator.
But yes, with a reduced load on the bike, the Shunt R/R will indeed be 'shunting' more current so it will dissipate more power than one running std loads.
And of course the reduced loads with the Series R/R also translates to even less load on the stator.

It's actually not intended to have liquid gas into the canister - it's only to catch the 'head' vapors; the vent goes via the roll-over valve and the only time this would see liquid gas is if bike was on its side - and then the valve prevents gas from leaking past it anyway.
The scupper drain is actually the 'overflow' (or for water) and that does not go to the canister anyway.

ok suppose when i am filling my tank and i do not stop at the shield (to leave a place for expansion )and i fill it to the top and let it set in the 110 plus sun where is that gas going to go?

 

[DEcosse]

the scupper drain is below the vent, so will drain before it gets to the vent.
Your classic probably doesn't even have an evap canister does it? (unless its a CA bike)

 

[TURBO200R4]

going on an old memory i think it had the evap set up. i have not had the cover off since i put relays for the lights a long time ago.

 

[TURBO200R4]

it may be a california bike because it had the secondaries restricted in 4th & 5th every thing i have read said threes were 100%.
