From the chart it appears the typical alterntor output, assuming cruising at around 4000 rpm, is more like 315-320 watts.
So what do the running systems require?
I've figured just under 100 watts for all the lights except brake and turn signals which would bring the load up to 135w. ( I'm using a 77w hi-beam).
The Gerbings rep told me that the FI takes 50-60w. This I'm having trouble figuring.
What does the ECU draw?
Coils and injectors?
Fuel pump?
If the 60w figure is adequate then the bike will run all its systems (except horns, brake light , turnsignals) on 200watts. Adding 99w of jacket and gloves takes the draw to 93% of capacity at 4000 rpm. Seems safe enough?
Add to this heated grips, a hotter headlamp or drop below 3300 rpm and it's you and your battery.
No doubt the earliest Sport owners were big contributors to the 6-speed R&D effort. Scura owners continue in selfless R&D of clutch-flywheel variations.
On my Sport's third three month warantee interlude for gearbox issues, the box was replaced. This had the 'final' upgrades of 2003. The '03 and newer certainly seem more reliable , overall, than the earlier units.( leaks, springs, shifting, clutch).
Thank a Sport rider!
No replys from LeMans owners?
I'm assuming it's like the Sport and you can pull the front cover forward enough to get the rubber bulb holder loose without taking the speedo cable loose.
The bulbs are 1.2w which I was able tho match to a 1.26w Eiko at the local Auto parts store.
That is a very nice machine,and an excellent example of something that actually is not a "proper Guzzi." Parked side by side, running or not, blind folded or blind drunk any rider in the world could pick out the real Guzzi.( Sorry , borrowing from another thread.)
Bummer about the clutches.
It's notable that the tanks changed in 2003.
Regardless of mileage and capacity if the supply runs dry before the light stays on, the inlet to the petcock probably needs cleaning.
Oil from the bottom of the engine near the junction of gearbox can come out the the drain hole in the bell housing . This could be either front trans seal or rearengine seal ( is it oil or gearoil?).
In any case, time to make the warranty claim in event it turnsinto something bigger. My Sport leaked there and munted the clutch at 4000 miles. Later ( 16,000 miles) a wet crossover turned out to be a case crack at the left upper mounting point of the gearbox.
For several stupid reasons I've run, or drained, my tank dry several times Typically it will run 5.1 USG out the petcock with another 0.7 in the right side of the tank. ( Yes, the tip-slosh reserve is effective if it doesn't crick your back!).
When my bike sputtered out with the light off I found the pick- up on the petcock to be all clogged with swarf. Cleaning it put me back to a light on at 4.6 USG with about 0.5 in reserve ( without the 'tip-slosh).
I'll take another look at the pictures tonight when I have time to let them paint on my pushrod dial-up. The side covers are the odd shaped plastic pieces that cover the side of the airbox and front of the subframe. There are three fasteners that hold them on.
Looks like that right side side-cover fastener has also gone away. Maybe time to rebalance those Throttle Bodies and apply a little Blue Loctite.
Bring it by the Lower Middle Muletown Guzzi Emporium for a tune! ( Bring your own Grappa ).
Well , I'm thinking time is important to us geezers, er, uh, Goozers, ahem, Guzzista.
We'd, perhaps, best not violate the Prime Directive, lest the future be altered.
Off somewhere there is a thread showing the body of these bevel drives pulling lose from their bases. This definately contributes to the bumping needle and the lash can't be good for the internals. Good news is they can pressed back together easily.
In some ways the spine frames are half -arrsed like the old Shelby Cobra. Charming but rough around the edges. Many things done for expedience. I waited three years for mine from the time the Sport was shown in Munich in 1997.
If I had waited til they sorted out all the kinks I'd still be waiting. No Breva 1100 in this neighborhood yet, let alone a Griso.
Aw, did I say 'worth less' . . . I meant priceless. You can't have mine.
I see my Sport is in the $4500-5500 range. Five years ago I paid the full 12000 USD. But just about any sporting Guzzi in the past 20 years are in that range. Any older ones are worth more.
I was alarmed how quickly the Sport dropped but by 2020 it should be worth more than what I paid for it.
