Well the new header was loose, no problem just tighten back up...except one of the bolts is missing.

So....what is the tq spec and why did one vibrate completely out?
I don't know the torque spec ... but if in doubt tighten it up where you had it on the install ... but this time USE LOC TITE! It will stay put.

Funny - I found a def for "Murcan" and slang uses 'mercan (American) but PC's Merkin looks a lot more entertaining. I didn't see one listed on their site, thank goodness....

Loc Tite on the header bolts?
I use anti-seize so I can get them out.

How many use Loc Tite in this application?
And do you use blue or red Loc Tite on the extremely hot exhaust header bolts?

I do use Loc Tite just about everywhere else.


blk-betty - did you put in a new gasket with the new pipe?

I've used both, but tend to go with Blue Loctite. Don't need it every time as it'll clag up a bit with the residue in there and do the job. Something, Loctite, or antiseize, reduces or eliminates the corrosion and bonding, so both work, but low strength Loctite is good.

Its also possible that the header didn't quite snug up, and after a heating cooling cycle, did, and there was then no tension on the bolts. A new gasket can exacerbate this behaviour.

Heat also weakens Loctite, so if you are trying to pull something apart, especially small screws, some heat can assist by not only expanding things, but weakening the Loctite.

Scientific

No worries. If I was back in the states I would totally go with the IMS. Adds just the right amount of range and looks right on the bike.

That XTZ 660 is a good looking bike! How does it compare to the DR650?

Haven't off roaded her properly yet , too shinny !!!!! but put it this way "the DRs staying" simple, tough and fits me perfect horses for corses !!
I've bought the Tenere for a planned tour dsown the West Coast of Africa in 2014 so need to spend loads on her yet. I wanted to take the DR but she's a 96 and i fancied something a little newer for the trip, that being said i my not have it in a year !!!
I will be dropping the motor on the DR and doing the 3rd and possibly other gears this year so MAYBE she'll go back to Africa , done Morocco twice on her without a hickup.

Thanks for the suggestions.

I tend to use blue loctite regularly but never used it on exhaust header bolts. I did use a new gasket so I think maybe the intital run didtn't get things hot enough for a proper re-torque. Will pick up some new bolts and will add a little blue locktite.

The only thing I have on that switched pair is a 12v cigarette outlet for charging my cell phone. I don't think a 5v USB charger is putting much of a strain on my electrical system, but I can always just not use them both at the same time. If I remember Webbikeworld's DR650 project bike, the electrical system was a bit under powered. I don't know if I would want to run heated grips and heated clothing at the same time anyways. If that pair can handle it, then I'm going to move the grips over to it. The less I have to worry about it, the better.

dr650 engine on ebay

seems a mite expensive, but still cheaper than installing new nova racing 3rd gear set, for you paranoid types...

She's a beaut Phil! In the US we've been proper cheated by Yamaha's reluctance to import this bike. She is a bit heavy though ... but I'd bet a good traveler.

A couple mods I thought about if I ever got hold of one would be:
1. Go with a single exhaust
2. Eliminate one front brake rotor.

Right there you've knocked off about 20 kgs. (+ -) Brake rotors/calipers are super heavy ... as are stock mufflers.

I'm thinking those two Mods would trim the BIG Tenere' down into DR650 territory.

You are one Hell of a Mud rider! I'd have been on my ass in that stuff!
(on my DR anyway) Cheers mate!

I believe there is high temp loc tite. Vague memories from A&P school. Don't over torque ... let the Loc tite hold things. Did you use a new Copper ring/washer in there? (I think it's Copper?) re-anneal the old one if you haven't done that. (Heat up to cherry red, let cool ... done)
