Might try a little duct tape on the air box opening, maybe close it off about a third. See if it cures the surging, or at least lets you know what direction to go when you want to fiddle with it more.
It is amazing how the opening affects the air/fuel ratio. Your just adjusting the air to the jetting, instead of the other way.
Worth a try and easily reversed.


Edit: also might want to look at where the carb vent hose/filter (the little filter under the seat) is hanging. some report that simply isolating it from the big opening in the air box top sometimes cures surging.

I just posted this over in the no moaning and pissing thread, sorry if there is some rule against making the same post in two threads but I couldn't be bothered reading the site rules.

I just got to thinking.
Everyone refers to the DR650 as the ultimate 'zombie apocalypse' bike.
Sorry, but I tend to disagree.
Why?
The bike is not fuel efficient enough.
Ok ok, the DR650 is quite a fuel efficient bike, especially considering how much forward-lurching torque blast-outta-da-cornerz fun it has, it really is.
But for a zombie apocalypse/post nuclear disaster bike? Sorry, no.
The bikes that will truly shine when shit really hits the motherfucken fan will be bikes such as the TW200, the CT110, the DR250, the XT200.
Bikes which use fuck all of nothing petrol and will get you anywhere and everywhere, and will keep thumping along happily all day. Because lets face it, petrol is going to be damn near unobtainable, and when you can get it, it will be very expensive (think $5 a litre) and people who sell it will be few and far between.

OR.

A multi-fuel motor equipped DR650, a la the HAYES-DT M1030-M2, capable of achieving near 100 MPG. Now THAT would be unstoppable.
Think of the logic behind it. A powerful, high-revving, torque rich, mechanical direct injected, indestructible engine capable of achieving astonishing astonishing fuel mileage mated with the most versatile best go-anywhere any-time bike known to man.

When the zombie apocalypse/post nuclear disaster inevitably hits, there's going to plenty of people scraping a living together making fuel this engine is capable of happily running on. It is going to be the most widely available and cheapest fuel in existence. After all, you can make kerosene/diesel out of used motor oil (providing you run it through an oil cleaner first) very cheap and biodiesel out of vegetable crops, and lets not forget the vast quantities of unused jet fuel that will be looming around in stores. All of which the M1030-M2's engine is capable of running on quite happily.

One of these days either Hayes-DT is going to release their magnificent single cylinder diesel motorcycle engine into the public sector, or someone is going to design and manufacture an equivalent nearly as good (perhaps better?) engine and make it available for sale to the public. I plan on being one of the first to have it adapted it to the DR650 when this happens, so that I will have the edge when petroleum becomes unobtainium.

I need to post a pic but don't have a smugmug or anything.
You can use Google Picasa or Photo bucket, both free.

Wow...that battery has the same dimensions as the OEM battery, except it's 3/16" taller, which should fit. More importantly, it has 230 CCA versus 135 CCA for the OEM battery.

Best of all, it's available on ebay with free shipping for $38 at

Right click on the pic in picassa, small or large, select 'copy image location'

Go to your post, click the pic icon, paste the image location, and Bob's your uncle.

OK, so just realized that my neutral light isn't working. How much trouble am I in and what's the best route to take at this point. I don't want to assume that the unknown to me PO did anything about fixing the screws or removing the NSU altogether. If it was removed would it be obvious somewhere where the cable exits the motor somewhere????

I'm not asking whether or not it surges constantly. I'm asking whether the severity of the surging changes with engine temperature.

Regards,

Don't run the engine anymore till you take the right sidecase off. You may find one or two screws loose in the bottom of the case. They are for the neutral light switch, it is a common problem. If you run the engine they may get caught in the gears.

What year, how many miles, just curious?

Don't let the length of this post scare you, there are several solutions for the same issue. Get a new gasket before you start, some break, some don't. Mine broke into several pieces.

OK. Does whether or not the cold start enrichment circuit is active make any difference to the severity of the surging?

Is the cold start enrichment circuit required to be active for it to start from cold?

Derek

I agree. Shut her down and pull the sidecase off and check those NSU bolts.
If missing, try to fish them out. Good luck!

DO NOT start engine until you've verified all is OK. As many know, the neutral light going away has been a common symptom when NSU bolts are missing.
A cheap and easy fix, best catch it before you have a problem.
