Oil coming out of tach?!?!

[e_sloan]

I changed my oil today, everything as usual (have to take off the damn exhaust to get to the filter). I went for a little cruise to see if anything was leaking.

When I got back I realized that oil had went up the tach drive and entered my tach. I am scratching my head as to what the problem is.

It is not a high amount of oil, but definately enough to make a mess.

Do you have a cable driven tach? I used to have a 79 XS750SF that did the same thing. The oil would wick up the cable from the spinning, and make a mess at the tach. You could probably find more info at the XS Triples site. Those boys are more familiar with that problem than the guys here. there is probably some kind of seal at the tach drive that is leaking.

Yeah its a cable driven tach.

Do you know any xs triple discussion boards. I have searched high and low for xj/xs boards and this is the only one that I have found.

tach oil

I have a80 XS850, cable driven tach, not leaking, but if yours is like mine, coming off the head (exhaust cam) as opposed to the bottom end, there are 2 O-rings inside the cable connector to the head, one is easy to replace the other more challenging, but mostly it's the easier one that leaks. Remove the part from the head, it is held on by the "Y" shaped bracket, and take it appart, only 2 parts really, you'll see the O-ring as you separate the 2 pieces.

Good luck

Here's the description from the Triple website:
"My Tach Drive Is Leaking All Over My Exhaust. How Do I Fix It?
Kirby Metcalfe
Buy the O ring and seal from Yamaha. Disassemble the cable from the drive paying attention to the way the loose parts are placed and oriented--especially the little Y-shaped retaining yoke; it must be placed so that as its screw is tightened it presses tighter against the flange of the drive. Make a sketch for the next time you DON'T pay attention.(Now is a good time to check the tach-drive cable. Pull it out and look at it. If it's nicked, replace it. The drive seal and O ring MAY come with a new cable.) Clean the parts of the cable assembly you're keeping down to bare metal, i.e., connector threads, cable end, etc. Get some FormAGasket or any good gasket cement. Coat the threads on the cable connector, the OUTSIDE of the seal, and location for the O ring and the O ring itself. A thin skin of the cement is all that's needed; try to avoid getting any on the cable itself. After lightly greasing the cable, reassemble the connection. (You may have to hand turn the cable end to align it with the square hole in the cable drive shaft.) Tighten it all down. Use mechanics pliers on the knurled cap and the Allen head wrench on the Y-yoke. (BTW, this method assumes the knurled cap has not been deformed by overtightening in the attempt to seal the leak. If it has, it's probably new cable time.) Final step: Start and ride the bike 'til the engine is up to temp then quit for the day. This procedure should solve your leak. BTW the shop mechanics won't bother. Oh yeah--if this doesn't fix it--try a heavier O ring."

I gave up trying to use form a gasket to fix it. So I went to my local dealer to pick up a whole new tach drive. Only cost 20, so once I get this installed the leaking better stop. I am getting tired of cleaning my bike.
