FAO Colibriman & Blade engine query
Hi,
Seen as you are the engine man, you may be able to help.
On a '98/99 Blade engine with the speedo sensor that bolts through the top of the crankcase, do you know what actually triggers it?
Is it a special triger wheel or one of the gears themselves?
Either way, I could do with the said ring and said sensor if you have either of them lying around anywhere.
Cheers,
Pat...

Hi Pat,
I've never had one apart to see what triggers it..give Marc at MNR a call as he had some in bits ages ago when I was there...
Meanwhile , as another option I was thinking about to your other thread...What about another set of blade clocks - an earlier set....
the 96/97 blade uses a sensor similar to the 98/99 one but its not mounted in the crankcase.
the 92-95 ones use a mechanical type speed sensor (ie spinny cable type not electrical sensor type)
I believe Hellfire 1 used this set up with the sensor 'wheel' turning with the prop..
(Hellfire..am I close?)
I have an earlier set of clocks (kms p/h though) and have a sensor wheel if you fancy trying that route.
let me know what you think...

Cheers Colin.
IIRC, I have a 98/99 loom and all other associated bits and don't think the earlier clocks will work with my loom and if I have to get a new
loom, that will only complicate/incur further expense.
I'll send Marc a message and see if has any ideas.
Have you got any fuel pumps lying around?
Cheers,
Pat...

IIRC, I've wired an older set of clocks to the 98/99 loom...they do work - not in my car. I used VDO gauges in mine
fuel pump...hmmm....I'll check, but I think I've only ones left with engine kits now.

Ah the old 'Blade speedo sensor chestnut again, one of lifes unanswered mysteries .
See previous posts and threads!
Anyway, my spinny speedo sensor is going to a clever man later this week to have the mystery unravelled once and for all hopefully, with a view to
sourcing an appropriate third part electronic sender unit-cheaply. However if If anyones got a spare, cheap, gearbox type one as per Pats post
i'll take it for investigation too.
IIRC Hell fire actually used the spinny electrical one on a bracket, run from the diff or driveshaft flang, i'm sure he'll confirm
HTH

From what I can gather, the spinny thing sends the same pulse up the wire to the dials as the sensor I am after - unless I'm completely
mistaken.
If that's the case, a simple sensor and a couple of magnets may do the job.

I seem to remember hellfire running the sensor with a rubber wheel running against the prob or driveshaft (or sommat like that)

Reman - If you come up with a little box to replace the sender, I can try in on my '98/99 clocks and then we can all have a laugh if it works
out that easy.

hang on a mo...I'm getting all mixed up here... (that ain't difficult)
right...
the early blade has an electrical spinny thing..
I have one + clocks
the cbr1000 has non electrical cable thing....
I have that + clocks too..
hence my confusion..
so..what was the question...? haha

I think pre 98 engines pick up on the sprocket don't they, which is this little wheel thing you're on about Colin, and 98/99 have it all
built into the gearbox. If, as I suspect it picks up on a gear, the earlier engine could easily be modded by drilling the block because the mounting
boss is still there in the casting, although you'd need to split the engine before doing it to prevent swarf getting in there.
Andy Bates at AB Performance might be worth a call as he rebuilds blades all day every day, although mostly for racing so might not know too much
about the speedo.
BTW, did you get my email about my head loom Colin?

The VERY early blade had a MECHANICAL cable like any ond car or motorbike, driven from the front wheel.
Then came the early blade which has the spinny ELECTRICAL sensor driven by the nut holding the sprocket on.
Then came the not at all early Blade with the sensor stuck into the gearbox pointing at objects unknown.
These two may or may not both work the Early Blade speedo , which is the normal analog needle face, after which came the later blade with a digital
speedo but thats chapter 2.
Even clearer??????

cant an hayness manual give you an drawing of the gearbox??
if it isn't there the unknown part then it isn't know where.

for speedo healers just make one your self

Cheers Colin, it's more use in my car ya know 
TKS - Ive taken apart a couple of 99 engines and the gearboxes didnt appear to have any kind of trigger wheel etc in there, although there may be one
integral to a cog or something that I didnt see, as I wasnt specifically looking for that.

I still like ythe idea that a different sender and magnets will work.
Will try and get hold of the later block sensor and then I can try and see what happens.
Watch this space.

I'm almost convinced now that the sensor is just a Hall Effect do dar.
Watch this space (don't know what for - I'm weeks of having a rotating prop and engine in the car).

Reman - which clocks have you got then?
I'll U2U MarkN and Rizla and see if we can find out which sensor they used.

No need to U2U. Marc's U2U said they used the later sensor (presumably the one that goes into the block) and two magnets.
Both sensors must be hall effect as the wiring diagrams are the same in the haynes and both have three wires.
Now just got to find that elusive sensor!

I've got the early clocks, electronic, with analog speedo dial. . I've wired the two together with a spinny sensor to check they work ok,
they do, just need to check the signal and replace the sensor with an appropriate fixed one..........
The race is on to obtain a gearbox sender!?

Ours was the spinny ELECTRICAL type sensor which runs off the bolt which holds the sprocket on (as described by Nuther Colin) but adapted to run off
the diff output flange as a wheel. Worked an absolute treat and will be used again on the next Fireblade engined car.

Speedo pick up
I have a blade engine that used the sprocket type sensor. Conversion was relatively simple! I used a photo cell to trigger the speedo. Simplicity
it’s self all I needed to do was paint white lines in the prop! To calibrate it I used the “new speed” spread sheet to calculate the number of pulses
required with my diff. The blade sensor has four pulses per rev of the sprocket. The end result was I needed 2.5 pulses per revolution. This was
achieved using a frequency divider i.e five white lines on the prop and divide by 2. Seemed relatively simple and it works – total cost less than
£2.50. If any one is interested I could go into more detail, pics etc.

ok...
you need an optocoupler...
and an couple of transistors..
the freq devider dunno how he did that but an way of doing is with an microcontroller..(there are easy ones that don't need much hassle..to
run)
now lets wait and see what he tells.
