Not sure about wd or tank? Maybe posted in wrong thread.

Nope. Jay313 asked what WD did with the hole created by removing the speedo. I responded that I thought WD did not use the stock fuel tank (in which the speedo is mounted), hence no gaping hole to consider.

Correct, I run a dirt track race tank of unknown date/manufacture. Nowhere to run a speedometer so need need for a cable.

I deleted the cable long before I swapped tanks, got sick of the gunk. Savages are a knock-off of an old British single (part Matchless, part AJS, part BSA) so oil leaks are expected. But NOT soaking into a water buffalo hide solo seat.

Boofer... I run a glasspack, 15" apes, no turn signals, FLH rear fender and low beam only 7" headlight. I get pulled over out of curiosity. And the bike regularly saw 100+ mph on the coast and around Millington NAS...

That's what I did and that's what happened. Thanks for the search and discovery Ben. Done. I'm glad it worked for you too.

Here's the pics and some updates.
I've been sick since I put this to test. So I only rode about 1000 miles. But as you can see, no leaks.

This didn't look good at first but upon closer examination I realized that the problem was that my 25 year old speedo cable was not smooth. More pitted and corroded. This caused it to tear the neoprene seal as it spins.

I put the whole thing in a drill and used some sandpaper and steel wool to smooth it out. Nice and clean. Let's try this again. I also put some lithium grease on it where the seal sets.

I cleaned this part as well.

See how nice it fits. Almost like it was meant to be there.

All back together. I'll give it another 1000 miles before I check it again.

If anyone else has tried this. Let me know. My bike is an 87 so my speedo was really rough on the seal. I'd be interested to know how it fares on a newer bike.

Reply #24 - 07/11/12 at 11:28:48 This fix is admitted by the author to be a work in progress that has not proven out so far. As such it is not suitable for Tech Section, where only 100% sure, proven out fixes are displayed for list members to copy. Moved to RSD until more run time and further refinements are done.

Reply #26 - 08/17/12 at 00:59:15 After removing my tank and disconnecting my speedo, my seal went awol so I'm trying this method. However, I installed with the metallic side on top, bonded neoprene on the bottom. I'll update in a month or so after I've got 1,000 miles on it.

I tried an O-ring (freebie) & it did not last long. It was 1/2" O.D. x 3/8" I.D. which made it only 1/16" dia. thick. I believe a 1/2" x 1/4" might well work, but did not have one to try.
I just put in a 1/2" x 1/4" x 1/16" thick neoprene flat washer. (At Home Depot in the same drawer with the bonded washers)
If this goes, my next trys will be to double the flat washers to get 1/8" thickness, or the bonded washer with a flat neoprene washer on the metal side (sandwich the metal washer), or look for a 1/2" x 1/4" O-ring.
I guess I'm a little leary of just the bonded washer because one side is still a metal to metal seat - (although that seat is concentrated to a knife edged ring because of the cone shape).

You might try this OEM number from Suzuki:
34943-11030
This ist the perfect sealing ring which is used on other speedo cables and tachs by Suzuki. Shocked

))

btw: if this seling gets lost, it sometimes hides under the starter motor if you don't find it on the road or garage floor. A quick take out of the starter may save lots of time.
