What Have You Done To Your Tdm Today? - bjorge - 12-09-2017
Quote:ÂÂ
They are using a single throttle body and two downstream injectors, probably employing all the tricks in the book to cut fuel here and there when not required, but ultimately (it appears to me) by restricting the peak fuel flow considerably.
Â
But the thing is, the NC750 is the smoothest fuel injected ride I've ever had. So these "tricks" do indeed work well.... It's fantastic on low rpms/speeds. Hairpin curves, for instance....
Throwing all in is a bit of a disappointment, though....

Today, I have decided that the 3vd needs a new coat of paint on the frame and swing arm. Along with other mods and refurbs!

I bet a programmable ECU would transform it

Rather: What has my TDM done to me today ?
Â
Stopped for the first time in 12 years / 67,000 kms.
Â
I hit the reserve about when expected - but the bike wouldn't run above idle. I was on the motorway but luckily <300m from a gas station. However, pushing the old cow that far would get me delayed and sweatty.... Then came to try choke - and it ran at ~3,000rpm with no throttle, and I could drive to the gas station. Filled her up, turned tap and everything was good. I obviously have a partial block somewhere in reserve outlet/tube/hose.
Â
But that feeling....disbelieve, disappointment....almost if I was left behind by a lover.....
orry:What Have You Done To Your Tdm Today? - bjorge - 15-09-2017
Just found this old post:Â http://www.carpe-tdm.net/ipb/index.php?showtopic=16296#entry162186
...describing the exact same phenomenon. An air lock preventing fresh fuel once running out of gas. Yes, I have been cranking the engine for minutes after running out of soup, too, but never from hitting reserve.Â
What Have You Done To Your Tdm Today? - Studley Ramrod - 15-09-2017
It does happen bjorge, I failed to hit reserve in time and it spluttered to a halt. Took a good few minutes to crank the fuel through again.

I fitted some new led handguards Album here   https://www.flickr.com/photos/142331699@N02/albums/72157686691728414The look of them seems to go well with the sweeps of TDM bodywork

Ebay, £20 http://www.ebay.co.uk/itm/2x-7-8-Motorcycle-Led-DRL-Light-Handguard-Hand-Guard-Brush-Bar-Protector-12V-/201970610937?hash=item2f0662f2f9:g:76UAAOSwDrNZVlc5
Â
Very similar to Acerbis devices here (wouldn't be surprised if the same company distributed them !) http://www.ebay.co.uk/itm/Acerbis-Black-Vision-LED-Handguards-8-Watts-for-ATV-MX-Off-Road-2367700001-/232425746897?hash=item361da771d1:g:~lUAAOSwFypZeV-x

Â
I've bought these as a testbed for my long overdue DRL modulator, which will glimmer and sparkle (not flash obviously). Similar to BikeVis Podmods (except those can only run 2 individual LED's  https://www.bikevis.com/product/bikevis-podmod-motorcycle-light-modulator/ ) I'm going to add motion detection, so that if you're stationary in traffic they don't annoy the car in front, and nighttime detection so that they dim the DRL's (officially DRL's should dim to 50% when the headlights come on)...I'm also considering making the leds flash more distinctively when you brake extremely hard

Looks very much like the same parts.
You may even add the brand name or your own name on the blank flat area !
Â
If you want to keep the modulator simple and avoid µC coding you may use just one 4093, it's enough for the job.
A second 4093 could then be used for the 50% dim time, to give a different pwm ratio and also detect nighttime.
Also the power supply is simpler with a 4093.
Just a thought...

 true but why avoid micro programming ? I'll be detecting motion using a £1 3 axis gyro with 3 axis accelerometer, so cmos logic won't hack it anyway !
Â
Also I'm modulating beetween 80% and 100% brightness at a freq of 16Hz ( the most noticeable frequency for the human eye)....so i need a bit more than cmos logic for that too. At night I'll modulate 50% - 70%
Â
i think I'll try to find some Acerbis stickers, then they'll look like i spent £100 more !

Stripped and lubed steering bearings. Fitted Renthal 755 (been meaning to do this for 8 months). And fitted a switch for a pair of the DRL's

Really ? how quickly was it flashing (..per second...) ?
Â
I think it's important to be careful with them because not only is there a very clear law about which lights should flash, but the effect is actually almost hypnotic
Â
I think it's really important to get the brightness of them down at night

I saw something like that earlier this year too, in the rain on the motorway, the guy coming along on the other side had his DRL's flashing at that slow rate which definitely cut through the spray, but like you, i found it too distracting. I think they're using headlight modulators to do it, which are common in the US, used to flash the main headlight at about the same rate. They're said to reduce the number of accidents........hmmmm.....
Â
What I'm working on is something which if you look directly at it you wouldn't hardly notice any flicker, but in your peripheral vision you notice it a little bit more.
Â
A frequency of 16Hz - 17Hz is the most attention grabbing but not the most distracting, oddly enough, it's similar to when an old bike or car is running from a weak generator and the lights flicker in time with the engine strokes. Used to see it a lot years ago...gone are the days !
Â
you see a lot of car lights flickering these days (only just), if you scan your eyes left to right quickly while looking at the back of a BMW or Audi (there are others) you can see that the rear lights are flashing. Same thing with traffic lights, LED low power ones flicker but you can only pick it up when your eyes scan side to side, through the use of LED multiplexing.

No offence but....ahem....the eye's ability to detect flashing deteriorates with age
