Hi,

Relatively new here, and I'm not very mechancally inclined, so please bear with me. (also, can't figure out how to search the forum, so if this has been covered as much as blue pipes, please be nice!)

I have a 2006 Bonneville Black. coming up on 2000 miles, ridden most days that are aobve 25 degrees, about 8 miles each vay on my commuts, and occasional weekend trips to the store. about 50/50 highway - street riding.

When I took it in for the first service (around 650-700 miles), there was a small oit leak coming from the rear cam cover. that was fixed by the dealer, under warranty, saying there was a wrinkle in the gasket when it was instaled at the factory.

Now, 4 months and 1000+ miles further down the road, I've got the same problem from the other cam cover.

Dealer said bring it in & he'll fix it...

Is this a common problem on the 790cc engine? Do I have a lemon? (doubt that...no other problems) Or does this engine just always leak oil?

Thanks

Lion

Have 8000+ miles on my 2005 Bonnie Black, no Oil leaks noted...

The cam cover gasket is alittle tricky to get right. Once it is right, you should have no more trouble out of it.
this kind of illustrates how many of us get started doing our own work. A dealer does the job quickly, and gets you on your way, hopefully. If you do it yourself, you take your time, use sealer, get the gasket in its proper place, have a beer, listen to a tune or 2, and before you know it, your fixed and back on the road.
Good luck,
G.

I think the bolts loosen up when the bike is new.
I did not have a leak there, but found the bolts VERY loose when I checked them at 2500 miles.
I also had a leak at the sprocket seal, loose bolts there as well.

Part of the new bike thing is going over ALL the nuts and bolts, as things heat cycle, they can loosen up.

Guess you never had an older Triumph, you would get into a mindset to check things every week, as despite locktite, lock washers, self locking nuts, something will end up loose over time.

thanks for the feedback. I wish I had the tools/time/aptitude to fix it myself, but I'm unfortunately stuck relying on the dealer. this is my first triumph after a succession of japanese bikes and an ill conceived venture into harley land...
I love this bike...a perfect commuter. Now if I could just get rid of that little voice telling me "faster...faster...you really need a speed triple" I'll be fine :-D

Welcome Mattrat. You've had solid advice. Generally the bikes are pretty sound and reliable. On the other hand many dealers are not. Oil leakes are a thing of the past with the modern Triumphs. Get yourself a Haynes manual and a couple of basic tools. My suggestion is that you should let the dealer fix everything in the guarantee period. That doesn't mean you shouldn't check his work after you get the bike back from his shop. Generally these small things are caused by dealer incompetence or more likely the dealer rushing to get the ***** (low paying?) guarantee job out of the shop.

My T-100 also developed a leak around the cam cover at around 600 miles. Took it in for warranty service and the dealer said it was a common problem and I might have to bring it back again in the future since the repair wasn't necessarily a permanent fix. So far so good, but definitely use the dealer while under warranty. It should be Triumph's issue to get it right.

Matt,

My 790 started leaking at around 2K or so. Searching this site made me realize many folks have this issue.

If you have the means, get a good torque wrench and download the torque specs from this site. Then check the torque on everything.

When I purchased my 06 Bonneville, my dealer told me to bring my bike in for the first service at which point they would change the oil and check and 'tighten' everything up as many of the fasteners come loose with time. I chose to do it myself for two reasons: (1.) I don't like to be away from my bike for too long and (2.) I just enjoy doing it myself.

:razz:

Anyway, if you question the quality of work your dealer is doing, dig in and do it yourself. There are a lot of great people here to help with just about any project you choose to take on.

And don't over-torque the cam cover bolts.
