It's a popular modification. Most of the ones I've seen run a long tube out of
the filler bolt, up to the fender and then down to the end of the fender (kind
of a big upside down "J".
The idea is to relieve pressure build-up in the final drive that causes the big
oil seal to blow. I don't have a vent on my '71 Ambassador but I use a high
quality hypoid gear oil that does not foam up and I've not had any problems.

It's not really hurting anything to have a vent, as long as it doesn't allow
water to get in there.
Cheers,
Dave

| My Ambassador came with what looks like a breather hood on top of the final drive filler bolt. It does not mist or get even the least bit oily at all. I have yet to remove it to get a better look as yet as the previous owner had a receipt for (fluid) being changed 3000 miles ago. I have yet to see another one like it on any other Guzzis I have looked at. Was this an add-on? Beneficial? Harmful? I plan on doing the refresh with moly soon but am curious about this. Ideas or facts? Rich ___________________________________________________________ T O P I C A The Email You Want.http://www.topica.com/t/16 Newsletters, Tips and Discussions on Your Favorite Topics |
