the DR650 thread

I need to fix the gearbox and engine on my dr and found a xf engine, both are same model year (1997). Has anyone made this swap before?

I am in Queensland, Australia.

What would I have to modify on the engine to make it fit? Other posters here have said that I might have to swap the head as the xf has 2 carbies. Would I just be able to swap the head from my DR onto it? I am not a mechanic, pardon my n008 questions.

Wil

while i dunno for sure, i can't imagine there'd be much (if any?) mods needed as the engines are identical except for the heads. if i were contemplating this swap, i'd be more interested in finding the dual-carb set-up from the xf rather than swapping heads to get your single carb to fit. the xf heads have bigger valves, why would you want the smaller valve heads of the dr?

More power to you. I would never attempt to tell anyone what (model) bike they should buy; but for what I'm going to be doing with MY DR650, you probably wouldn't want to do on any $5000 GayTeeEmm? See below:

Close to stock, I shimmed the needle,desnorkled. removed the brass cover off the air fuel mixture screw,
KN air filter,renthal bars,acerbis hand guards,250 tail light. also in the process of making a skid plate.
Thanks for the helpfull information. still got some pages to read.

What the heck!

Repleced the snapped head pipe with a FMF PowerBomb. After the install and a short ride retorqued the header bolts. Admit I don't know the tq spec but thought they were damn tight.

Rode little over 100 miles today and when bike cooled checked the status of the header as someone mentioned that things may have been too tight without enough flex as a reson the OEM snapped at 6000 miles.

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?

Locktight is your friend. Without locktight or a lock washer, most things will vibrate undone. Heating and cooling makes things even worse.

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.

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?
