airheads and water crossings.

With my D/S thumper, I can pretty much go as deep as the airbox or exhaust pipe. That started me wondering about airheads which seem to have lots of "holes" considerably lower. Can I dunk my G/S or will I regret it? How deep is deep?

I've had my R75/6 up past my ankles.

My dad claims to have had his R75/5 up to the tank(!), but his memory might be a bit fuzzy.

I've been wondering the same thing. The electrics are high up and the breather for the final drive can have a snorkel fitted but I have slots in the my front cover, I'm assuming to allow some air out of the alternator for cooling? There's the speedo cable, and the hole on the left side where you can see the fly wheel. Can those be plugged safely? The place I usually go offroading at has two creeks I have to cross or my riding area is very limited. I remember having water almost to my knees on my KLR when crossing them, I'd hate to have to avoid things like that on the G/S.

If plug cables are healthy the engine will run as long as the airintake is above water.

The electronics behind the front cover seems to work fine, but the gen-light often starts to flicker when the alternator gets to wet (no worries).

I think the clutch is the worst problem, the clutch housing gets full of water and if you use the clutch (esp going uphill) it might start to slip.

It might be smart to find another way to vent the gearbox and final drive,
but itís not strictly necessary if you check/change the oil pretty soon.
When you drive in salt water you should clean your bike asap, corrosion starts fast (cables, bearings, leverage, electronics ++)

I destroyed the output shaft on my '83 R65 with injudicious use of a pressure washer. I figured I knew well enough what to avoid, bearings, electrical, instruments, etc. I didn't know enough about boxers tho. I got too much spray up under the engine and into to clutch and splines and stripped the lube out of the spline. About 5k later I was left stranded on the road. It was an expensive repair and now I know much better. New bikes must have fixed this weak spot, but I'd be wary of dunking this part of the bike on any model like mine.

My G/S which lead to this question is essentially the same as your 83 as far as "achile's heels" goes.

Did you get that much water in the speedo boot/hole? Or where? I.e. what do you mean "under the engine"?

Itís originally a GS Basic (last airhead build in Europe) which was converted to a Kalahari (upper pic). Itís now converted to a HPN Rallyesport (lower pic).

The fairing fits both a standard GS and G/S with a HPN-tank.

I rode the Sheetiron on my R80G/S and took a hard split by accident. naturally there was a water crossing. lots of people falling over and getting hauled out, so I set up and went where they were NOT going. No problem.

Water was over my ankles standing on the pegs.

Great mod. Please tell us how well they work after you tested them.

I had some fun with solid works and thought about 3D printing.
But for bigger parts it's (IMO) way to expensive.

If not 3d printing, that'd be a fine candidate for old fashion fiberglass or carbon fiber.
