Upgraded the LEDs in my handguards, they were pretty poor.

 

Old ones on the right guard (rider's right) new one on the left

 

Camera auto exposure making everything look brighter than in reality

Just finished valve clearance adjustment, and fired her up!

Still got bits and pieces to do, but engine sounds sweet.

Must admit, I'm struggling getting the airbox back on properly.

Must just add big THANKS to Dappers for the help with providing all the shims from the Carpe repository. Only 2 were not spot on in the end, but are now in spec.

All the clearances were tight in varying degrees. managed to swap 3 and remaining 7 supplied from dappers suppository collection......cheers fella!!

Got lucky just before Xmas and got a pair of Scorpion cans and link pipes in great condition for the TDM for £90.....haven't fitted them yet, just waiting for some nicer weather.

 

Be patient, plenty of cans on Ebay now and then.

Ive vowed to save money for next christmas to buy some bargains.



Bought my 9er the week before chrimbo for £925......agree that patience is key

Took the Mk1 for MOT passed no advisories, need to check battery charging rate a little high  but battery voltage not confirming that.

Well done on the pass !

 

How do you know the charge rate is too high ? Are you reading an ammeter ? Or is the battery boiling dry  ?

Reset the CO values to standard + 8 on both cyls

 

I have a theory that  CO1 and CO2 are not a fuel/air mixture measurement or setting (CO usually refers to carbon monoxide doesn't it), but is 'COrrection' - in the same vain as  when you replace a lot of different types of fuel injectors, you need to tell the ECU what the new injector's correction value is (difference from an ideal injector)....because every injector is created slightly differently and therefore they all flow slightly different rates

 

So when I started with +12,0   I have now added 8 to each because of the free flowing exhaust, to enrichen both cylinders by the same amount , to end up with +20,+8. Seems nice and smooth.

 

I had orignally set them both to +20, based on other people's comments, but it seems too 'monkey see, monkey do' now, so I'm giving this a try.

 

On the back of that, has anyone changed a throttle body/injector as per a Yamaha service guide....are you asked to enter CO values ?


What Have You Done To Your Tdm Today? - fixitsan - 01-02-2016

Oh well, might have somethign else to consider..... I just found this on a Yamaha group with repsect to the R6...it seems they have C1 thru to C4 to play with, which might seem like cyl1 - cyl4.

 

But someone dug out an R6 OEM manual and found this.....

 

 

C1 and C2 focus on smaller throttle openings and a setpoint of 3000rpm....just where a lot of people complain about the running of the TDM900

 

 


Quote:Directly From the R6 OEM MANUAL for assembling the bikes

 

Before changing the settings, check the engine for its characteristics in normal

It is recommended that the settings be checked with an A/F measuring instrument.

Guidelines for setting

• Code C1: At 25% or less of throttle opening and at 3000 rpm or less of engine

This affects the idling stability and the feeling experienced during

Too rich an air-fuel mixture may foul the spark plugs.

• Code C2: At 25% or less of throttle opening and at 3000 rpm or more

speed:

This affects the feeling experienced during engine braking and

throttle opening.

Make a change of 2 to 5% at a time while checking for any

changes.

• Code C3: At 25% to 90% of throttle opening:

This affects the feeling experienced at half throttle opening.

Make a change of 2 to 5% at a time and check for any resulting changes.

• Code C4: At 90% or more of throttle opening:

This affects the feeling experienced at full throttle.

Adjustment to too lean a mixture will lead to engine breakdown.

Adjustment by checking the A/F is recommended.

In particular, to adjust on the leaner side, make a change of 1

time while checking for the result. 12 to 13 is a targeted A/F.

Have to admit this sort of stuff goes over my head but i seem to recall it being mentioned that both settings should be set at different levels due to the fact that the left cylinder gets more external airflow than the right side with the cam chain  :dunno: never touched mine as i dont really know what i would be trying to achieve and all seems to be working well just now.... it's all a mystery to me.

I sionce found a Yamaha service manual for the FZ6, which says C1 is cylinders 1 & 4 , and C2 is cyls 2 & 3 . 2& 3 are in the middle of the engine, get hotter, and should therefore be set more rich. (or at least it should be a consideration. Setting leaner values increases heat.

 

Using that info and applying it to the TDM that would mean that the right cylinder gets hotter, and therefore should be set richer. As standard mine were set the opposite.

 

I'm still thinking along the lines that these values are merely trims for the injectors.......but then there are only 2 values to play with on the 4 cylinder FZ6 !

 

Also the TDM is water cooled so differences between cylinder temps are less likely to be huge when compared to an aircooled engine.

 

It seems fairly accepted that a higher value increase fuelling anyway, so I'll fall back on spark plug inspection and riding feel, and take it from there.

 

 

 

 

 

Today's job was to book an MOT for Friday morning. I'm on the nightshift this week so I'll ride it in just after work. Gives me a couple of days for minor fettling.

Yea, I bet the 9'er really needs a good restoration. Hope you won't be too disappointed once you've sorted it !

Anyone know the standard CO settings?

There isn't a standard setting. We all seemed to have had different default settings. I've got mine written down somewhere.

I believe they're different, because it all depends on the specification of the injectors, among other things.

 

If you change an injector on, say, a Fiat 1.9 diesel engine (electronic injectors)  you need to take the calibration value sent with the injector and using your laptop punch it into the ECU, so that the ECU knows the true flow rate of the injector.

 

Most injectors produced by the same manufacturing lines will have slightly different flow rates. So for example a 1ms pulse duration to one injector might produce a 1ml volume discharge.....but on another injector it might produce 0.98ml and another might be 1.03ml.  

 

To compensate for these differences injectors are often supplied with calibration values and I wouldn't be surprised at all if the CO settings are related to the injector calibration values in some way.

 

The ECU uses this compensation or calibration value when it commands the injector to open, such that if it wants, say 1ml of fuel to be discharged then instead of sending a 1ms pulse, and if the injector flows less than standard, the ECU sends a pulse which is slightly longer than normal to compensate for the difference. Likewise, if the new injector has a higher than standard flow rate

the ECU will compensate by commanding it to open for shorter durations than it would for a standard injector

 

But then again I haven't seen a service manual which covers injector replacement - that might be where we could find out for sure.

 

 

 

 

Have to admit, I've only got experience of this with high pressure diesel direct injection systems. Where injectors are trimmed up in the ECU, But after reading other Yamaha forums where people ask about the CO settings on their Yamaha, the same answers relating to manufacturing tolerances of the fuel injection/throttle body keep coming up too.

 

Here's a diesel based explanation ! http://pmmonline.co.uk/technical/diesel-injector-coding-ford-mondeo-2005

Got a puncture on way to work, tyres were already on the wear markers so bought a shiny new pair of PR3s on way home from work, unsurprisingly, they feel completely different to the very well worn badly squared off roadsmart 2s that they replaced.

What Have You Done To Your Tdm Today? - fixitsan - 03-02-2016

Prepped for the MOT, chain is almost out of adjustment range and the rear tyre is low (haven't got around to swapping it yet), but those things apart it should be a solid pass...... fingers crossed !
