Finally was able to get the bike out on the road after 16 months in storage (shoulder replacement surgery). Unfortunately the next day, I noticed my gearbox drainage hole was leaking oil. Drain hole stripped. Not Good! New to North Carolina and found a new Moto Guzzi dealership but for two weeks they've been trying to get a hold of someone in Italy to guide them on a fix. I'm not sure what my question is except... What are my options? Has anyone run into this issue? Man, I was looking forward to riding my bike this fall.

Thanks, Gregory S.
 
Number of options:
Oversize drain plug. Generally not a good option but have used it on various machinery.

Heli-coil: This used to be the standard for fixing stripped threads but sometimes the heli coil will back out.

Time sert is the new standard & best fix.
This is a bushing that is threaded on the outside & inside.
A machine shop or general repair shop could do it if they have a way to get the bike in the air & enuf room to work on it from underneath.
 
The dealer must be real new. The correct way is to call Guzzi's Regional Technical Rep here in USA. He is there to assist dealer mechanics with their problems that are unfamiliar. If they don't have his phone #, have them call warranty dept. in CostaMesa, CA and get it but it should be in their paperwork. I would go elsewhere if the wrench's are not experienced enough to know what Trout has explained.
 
Thanks for your replies!
The time-sert looks to be the best option since we're talking about a plug that would be removed occasionally. My concern with any of the options is getting to the plug hole where the fix would seat the bolt correctly. I'm told if the heli-coil, time-sert or an oversized drain plug isn't recessed strait, it will leak. My other concern is there enough meat in the aluminum to hold a time-sert?

The dealer brought on the Moto Guzzi line about 6 months ago and from what I'm told, 2 or 3 of their techs flew to CA for training. So I'm a little confused as to why the first step wouldn't be to call Guzzi's Regional Tech Rep? I wish I had other options for a Guzzi dealer. I did however found a machine shop that specializes with rebuilding older Guzzi but he tried to sell me on replacing the oil pump at the same time they were doing the work. This gentleman said that there's been a rash of oil pumps failing on California 1400 bikes and the cost to fix is close to 2500$. I couldn't find any information regarding this to be true so I decided not to have him work on my bike.

Very frustrating. Can't find anyone with the chops to fix my bike and the one shop that can, want's to sell me something that I don't need.
 
I have used both Heli-coils and Time-Serts. I do like Time-Serts. They are not that hard to do. You do want to get them straight, but it isn't that hard to do. And a drain plug on the trans isn't a high pressure plug. This should be a one day in and out deal. Or you could do it yourself.
 
+1 on what GuzziMoto said. Probably a 30 minute job. It's a easy fix. I have had nothing but success using these methods. I would only add that I use a left hand drill as a precaution to keep shavings out of the case. Maybe a quick flush after. But it's a permanent repair.
