Is it normal for brand new engine to weep oil...

I just picked up a brand new 2012 Bonnie SE and it only has 40 miles on it (that i put on between riding home from the dealership and taking it out for a short spin today). I've noticed that there are a few spots around the gaskets (head /valve cover) where it looks like it is weeping a bit of oil. Is this normal during the break in period for a bike?

All of my bikes have leaked oil...but that is because they were all ancient pieces of junk.

I am obsessive and this will drive me crazy until someone tells me its normal (calm down Russ) or that I need to bring it back to the dealer.

Thanks in advance!!!

Can't believe that is still a problem after all this time. Yes, sadly, completely normal. But, happily, nothing but a cosmetic issue.

Have the dealer fix it under warranty, they're used to it I'm sure. No hurry though. Wait for a spate of bad weather so you don't miss much riding

There are remedies for this but if this bike is THAT brand new, then I would turn around and go straight back to the dealer. It would make me wonder what else on the bike needs attention

What does the fix entail? Is it simply caused by the gaskets not seating properly? Cylinder heads not torqued to the correct amount?

On my thruxton they replaced the gasket first and then eventually the whole valve cover. I also had a problem where a plug at the rear of the engine wasn't properly torqued. When I traded it in it was leaking again - probably from the rear, but not sure.....

Do a search for cam cover leaks and you will get a plethora of info. Historically the issue has been the washers under the shoulder bolts compressing too much. The shoulder bolts only screw in to the shoulder and voila, a very slightly loose cam cover that can weep a wee bit of oil.

This is just a guess on my part as I can't actually see the bike but it would not surprise if the dealership used the old style cam cover bolts seals or the cam cover bolts.

Triumph changed out the thickness of the cam cover bolt seals and the bolts because of the weeping issues that these twin were very well known. This solution was a pretty much a sure fire fix to the problem and is why it makes me think that you have a set of the old style bolt seals in there.

Part # T1260309 are the BAD bolt seals that you don't want and will weep on you.

Part # T1260337 are the ones you want that has fixed this problem. My bet is that the dealer had some old stock or whatever reason...but you don't have the right bolt seals sitting in it. It is a 10 minute fix that redefines simple but this bike is WAY too new...the dealer should do it

Why would the dealer have put wrong parts in the bike? The bike is brand new and came directly from the factory. They would have no reason to take anything apart before selling be the bike.

It could have come from the line this way as well...mistakes happen but the symptoms you are describing makes me think you have the old style seals in there. This is not something you would know unless you are riding the bike down the road and the weep starts

Here is something on youtube explaining exactly what we are talking about here. Pretty cool as this is about the only mechanical stuff I have found on the modern Bonnies with youtube but it explains this weeping you are asking about
