So is 16.7 km/l bad with a TM40?

It's the same as i was getting out of the stock carby.

Might need the leaner Main jet

Depends where your riding, As a comparrison coming home from Springsure doing 120 on a DR speedo that probably is only 110, i averaged 19.28. i used exactly the same amount as the DRZ 400 i was travelling with, in the slower stuff he was fractionally better. So that's with a stock carb, so since i did my carby mods my fuel range is a fair bit better and it runs great.

try leaning off the pilot jet as that effects cruising economy more then the mainjet
remember with the TM40 a higher number pilot is leaner
ie. a 17.5 is richer then a 22.5

Ahh, righto, thanks for that.

That fuel economy was made with a hell of a lot more fun than with a stock carby though

I got from 11 to 20 km/l on the open road.
15 km/l was about the worst with the BST40.

the pilot and needle effect the less half throttle stuff
the mainjet controls the fun stuff.
dont miss out on the fun stuff and the TM40 contains way more fun stuff

1/ Acerbis tank fits my new DR fine with a 39mm FCR fitted, no clearance issues at all.

2/ With all the carb mods performed on the stock BST and then with a Dynojet kit fitted, there was still no comparison to the overall performance gain right thru the rev range with the FCR - PLUS fuel economy is better!

3/ Old Chinese saying...."hah, you cannot make silk purse from pigs scrotum"

Fcr's are cheap too, i just picked up a 40mm gen 3 for $250 and i bought a 39 gen 3 for less than $200 a few months back

most people would be able to knock up a addapter ring out of a peice of pipe with some hand tools and mugiverissem

the old gen 1 slant body 39mm fcr's of the ktm's are a nice fit for the dr without having to change much, there smaller than the newer fcr's so there easier to fit and work on.
They have a plastic bolt on bell mouth that is just slightly too big for the dr's air filter boot (it can be easily shaved down with a knife), the other end is the perfect size and there already the perfect length.
you'll need to swap your cables or alter the originals.

If you do decide to buy an early fcr make sure its not leaking fuel from where the two halves of teh carb bolt together.
The americans have issues with the gasket/O ring disintergrating, it doesnt seem to be such a problem overe here so maybe they have more ethanol in there fuel.
The gasket that leaks is not available to buy as far as I know.

DR 659 Throttle Tube 2007

Fitting Heated Grips to my sons 2007 DR 650. Got the left side off no problems. Throttle tube presented a different situation! Attempted everything possible before finally dismanteling tube and trying to cut the old grip off. AAhh..I knoe, I'll order a new Throttle Tube. New tube arrived in 24 hours..but..it has a bloody grip firmly attached. So, my questions, 1) Can I purchase from some source a Throttle tube to suit the 2007 DR650 without a bloody grip attached?, 2) If a gripless Throttle Tube is unobtainable and I perservere with my scraping/cleaning of the old Throttle Tube, do I have to grind off the small lip on the external end of the Tube, in order to fit Heater Pad and New Grip? Any suggestions greatly appreciated. Thanks.Rod

Cheers, Pete.

The stock DR grip after cutting as much off as you can will come up nicely with a wire buff,be careful of course.

A TM40 uses a VM28/486 series pilot jet. Sizing on a VM28/486 pilot jet is larger number equals richer. In fact I don't know of any Mikuni pilot jet where the sizing is larger number equals leaner. The only time this is the case is with regard to air bleed jets. The TM40 does have a BS30/97 series pilot air bleed jet, but this should not be the primary means of adjustment, as it controls the slope of the delivery (whereas the plot jet moves the entire curve up and down without changing slope).

Regards,

Derek

The needle does affect all ranges, but because it can be difficult to manufacture enough needle shapes so that there is one for all applications that works well at all openings (case in point, the FCR), the pilot jet overrides 1/16 and 1/8 openings, and the needle jet overrides 1/4 opening. Effectively this means that you only need to be concerned with needle shape for 1/2 and 3/4 openings.

Regards,

Derek
