Topic: tach plug/centre mounted speedo

[smashedmelon]

Has anyone taken off their tach and used a tach plug for the port (in place on the cable)?
I found a chrome tach plug at cycle x........wondering if I should put a new seal in?

I tried the pointy chrome one off a ebay. It didnt fit right managed to break the screw off in the valve cover. Drilled it out and re-taped to m6 now has a proper 8mm head on it instead of the easily stripped screw. Cut off the end of the old tach cable so it would protrude a few mm's from the valve cover, screwed in a self tapping button head screw in the whole where the cable came out with some rtv on it to seal it. Works great.

thanks for the help. Are you running a stock speedo? I work in the steel service industry and was thinking of gettin one of the small fab shops I deal with to make up a bracket to centre mount the stock speedo. Has anyone done this?

I just cut the end off my tach cable,tapped the hole and put a small cap screw with an o-ring and some blue loctite and then cut an o-ring groove in the o.d. of the housing. No oil leak for me. I also took 2 pieces of 1/8" X 1" steel strapping and made my own speedo mount to center it. Took about an hour to drill the holes, bend and twist it to suit and paint. I think mine looks good and it holds the speedo very solid. No problems with viberation at all.

Don't know if this will show you anything to help, but here's my center speedo mounted.

I can see that headlight clearance issue would be my main concern, although if I end up using clip-ons I may be able to lower the headlight a bit.
thanks for the pics!!!

Would something like this work for your tach plug? I made it from aluminum bar stock, so it should polish up nicely if you want the chrome look.




It's a slip fit plug that I made. Add a little RTV or O-ring  under the head and it shouldn't leak at all. OEM bolt holds it in place.

I could probably make a decent center mount for your speedo as well. Let me know if you'd like me to whip something up.

The one from Cycle Exchange works great no problems.  At least for me...

If Melon wants it, it's his free of charge. I don't really have a use for it - just wanted to see how hard it was to make it.
