Raptor Chapter

Never had any of this with either of my tanks

Logic would indicate that the problem must be caused by "man bits", then.

Neat!
I mean, err…
Tut, tut… how anti-social.

Your average motorist's idea of a dangerous activity:

Don't know if this is relevant in this case, but when I first had my Rappie I had real difficulty getting the tank front bolts back in. I can't remember if the tank was too far forward or rearward, but forward would be my guess. I imagine that under repeated severe braking the weight of fuel and the...

So far:
BP Ultimate and Murco: Ethanol-free, at least in Worthing West Sussex, UK
Tesco: 4% ethanol

More as it happens…Please contain your excitement.

Water: Fuel: three drops of dye, shake, and leave to stand: That looks like about 4% ethanol, given my usual inability to quite get the levels to the line.

At last, a result…
Tesco 95 octane unleaded:

For a thread that started off on Throttle Position Sensors, it sure wandered about a bit :) On TPS: when I first had my Raptor I had too many incidents of the engine cutting out on shutoff and a tendency to splutter when opening up hard from low revs. Reading comments here led me to conclude that th...

On Shed's point about lowered octane rating:
Apologies – I had seen this mentioned several times during my initial research but forgot to mention it.
Those that had made this comment had also suggested using an octane booster.

Add three drops of dye and shake as per instructions; allow to settle: P1030944_2.jpg Shock, horror! :shock: No change, therefore no ethanol! What is going on? Well, it turns out that my daughter may have chosen a fuel supplier that still does not have ethanol added. My first reaction was that my te...

Second test: Murco 95 octane
(I don't know the actual Murco designation, as my daughter got me a jar full when she put fuel in her car yesterday and only made a note of the octane rating.) Water level: Fuel level

Boy, could this get heavy. Go ask Vincent or Edvard. Not that you can. Vincent went under; Edvard recovered. A pastel version of The Scream sold for just under $120M last year. Go figure. I had a pretty bad patch back when I was forty and still have the occasional "unmotivated" days. Now, ...

Thanks for that, Shed. Having tried to make sense of the manual, this really will help. Shame it wasn't just a case of taking out the bolt at the bottom and draining it, though. Ho, hum… :( I've copied your text and produced something that I will be able to print out and use. Maybe I'll add it here ...

I haven't tried to do this either – and, as far as I can see, the Cagiva documentation seems to avoid considering this as a stand-alone maintenance operation. It is mangled in with dismantling and overhaul of the fork (Section E: E6 to E12) Do you have a copy of the workshop manual? If not, I could ...

Here's a short YouTube video which illustrates the process quite nicely:

Final comments on this particular test: Here is a photo showing the small syringe that I used as a dropper. I have placed a £1 coin in for scale. P1030935.jpg Although I have determined that my local BP Ultimate is ethanol-free, there is the very unlikely possibility that the test is faulty, so I'll...
