Should I rebuild my engine, any advice?

The tach drive sleeve has an O-ring on the outside and a seal inside that contacts the drive gear. It also can wear a groove in the drive gear. All are cheap to replace. BWringer has a great write up on the job.

My cam cover was leaking and showing up down below, looking more like a head or base gasket leak. Around $50 for cam cover gasket and rubber end plugs and no wafting aroma of hot burning oil!

Thanks alot. Ill start with that cause it does seam to be coming from that area.

As others have said, it may not be leaking from where you see it. It could be dripping down and blowing around...

Clean up the engine really well, then ride a couple miles. Check the tach drive seals and valve cover, etc. This could be a quick and easy fix for you.

Even if it is the head or base gasket, it's not as difficult as it might seem to you now to replace them.

If the leak is not from the tach drive or valve cover, I have a rebuilt GS1000G (with CV head) engine with new rings.You can have it cheap and I will maybe go to calabogie motorsport park in two weeks.

So looks like its the tach seals (replacements on the way) only problem is that damn screw is seized. Hahaha. They're always seized. Lol20170822_173336.jpg
