You really should check all the cylinder head bolts, rather than torquing only two. Plus the leak may be coming from the valve cover and not the cylinder head gasket.

EDIT: eakins beat me to it.

Does anyone recall seeing it?
AND, do you remember where you saw it?

It was a LONG post listing dozens, if not hundreds, of bikes by fork diameters.
I don't remember if it listed other dimensions, all I recall was diameters.
I have tried searching using every term I could think of and I am getting nowhere in any thread or forum.
Seems to me it was in a discussion of fork swapping...
Since this thread is one of my daily reads I have tried here as well as Thumpertalk and other DR650 sites.

One of those things that we read and think "that is really interesting and useful" and then forget to save it somewhere for when we want it.

Or maybe I am the only one who forgets everything...

Uh, never mind. Dumbhead finally thought to search on Google and instantly hit multiple sites with the chart....
Thank you for your time, now we may get back to the regular discussion of pilot jets: "to clean or not to clean, that is the question..."

For anyone who has a lousy memory like me, here is the original location (as far as I can tell) of the Fork Tube Listing I had searched for:
http://www.ohiocaferacers.com/
It is in the Tech Tips section.

They also have a chart of "Stock Steering Stem Sizes" which is also very helpful so you may want to save both of them.
I have saved the links, and saved a PDF file of each.
Next time I ask where this is, perhaps one of you fine people will remind me that I saved them....

The link I had remembered was actually this one:
http://scandalon.com/2009/06/motorcy...iameter-chart/
But it is nice to give recognition to the ones who actually put it together.

The All Balls website lists the bearing sizes for forks which is also very handy. With all three lists, you can figure out if what you plan will be feasible. Without breaking the bank for custom machine shop work.

Good point.

It's kind of like medicine. Odds of 1 in a million for having a bad reaction to a drug or vaccine sounds good unless you happen to be the 'one'.

I guess that's why I finally removed my chain roller too.

Short version is that if your chain tension isn't loose enough you can rip the upper chain roller and it's mounting point where it is attached to the frame right off the bike. If you remove it, your chain doesn't need to be adjusted as loose, which makes it one of those 'Catch 22' (does anyone still remember what that meant?) things.
As in all things DR, opinions vary and anecdotal evidence is always considered 'proof'. I took mine off. YMMV, enjoy the new toy!

No agenda here other than trying to contribute to everyone's general understanding. Just pointing out that the majority or DR owners won't be happy with a 45 pilot jet. Neither would they be happy with a cut open airbox and a shimmed needle. It worked for you so more power to you. Your bike responds differently than 99% of the other DRs. We do see this occasionally. On the other side of the balance is the bike ridden by one of my employees. He has a cut airbox but still has a stock exhaust. His bike wouldn't run properly until we set the DJ needle on the 5th position. That would be way too rich for 99% of other DRs but his bike ran great with that setup and got 53+mpg. Most other bikes with his setup would need the needle set at position #2. Go figure.

Question

Is there any way to confirm visually (while bike is assembled) if you have a paper base gasket or a metal base gasket

I have the same setup your employee has - cut box and stock exhaust. I have your kit installed with the suggested jet/needle position for cut airbox (don't know what the exact figures are but I went by your included suggestions). Pulls hard but has that off idle bog and low speed surging. Screw 2.5 turns out. What should I play with the dial it in? Needle position? Main jet? Pilot jet? Fuel screw?

I'm contemplating just ditching the stocker and going with your pumper....but the wallet is not fat enough at this time....

Yes there is. Look up under the bottom cylinder fin on the right front 'corner' of the motor. This is an '04 steel gasket, I don't have a clue what the paper one looks like (does this tab exist on the paper gasket?).

Look for this:

The paper gasket does not have a tab.

(I can see the flood of responses coming now )

I still have mine as well. Here's one for the opposing view...

During what throttle position(s) (1/16, 1/8, or 1/4 opening) does the bog and low speed surging occur?
