Griso injector leak

Can someone just tell me how this is supposed to work?

This is a 2008 1200 Griso. I hadn't ridden the bike for a while as I have been playing with a Superduke 1290R and a 675 Daytona. But that's another story.

I rode the Griso to work yesterday and all was fine. But this morning when I switched on, the right injector just pissed fuel. I didn't have time to investigate, so went on another bike.

When I investigated this evening, I found that the whole injector assembly was loose, and the fuel supply had come away from the injector. Now it looks as though the injector seals into the head as a push fit with an o-ring, and that there is a similar push fit and o-ring into the fuel banjo, the whole lot being secured by the single socket head bolt that also secures the plastic guard.


I have reassembled it like that, and we are up and running. But I'm just puzzled that all this stuff is held together and sealed by the clamping force of a single bolt. Is that right, or am I missing something?

<scratching head> Why wouldn't a bolt do the job?

[pete roper]

Yup, that's right. As Chuck says, why would it need more than a single bolt?

[Trogladyte]

Yeah - fair comment. I'm not sure why the single bolt seemed inadequate. I think I was probably imagining fuel at very high pressure being held back by a puny fixing that was also holding a bit of bodywork. But now that I think about it, the fuel pressure is probably not that great.

Anyway, it all seems to work, so thanks for reassuring me that the way I have assembled it sounds right.
