Thanks Ian for putting me in touch with Steve, he sent me some great photo's of the head which sadly, using the links that Charlie posted as a guide, fits all the criteria for a V700. It looks to be in perfect condition if anyone out there needs one.
Since then I've bought a couple of T3 heads which, I believe, are the same apart from having bolt up flanges instead of the original threaded ports. |

I'll ask him if he's still got it, and pass on his number if so.

I might well be interested in the 4 speed box if there is no other interest.

Back when the weather was hot. A few flakes of snow today!
Here's another 850GT encounter from a couple of years previously. As always mine was the scruffiest. Only a few frame numbers apart these 2. |

I'll PM you his details, although I think he's up in the North East somewhere. He's having a bit of a garage clear-out, so also has a 4-speed loop gearbox he wants to get rid of. Not suitable for my bike which has a 5-speed. Ian

When I had my Norton Commando head refurbed I also had the exhaust ports redone with a new inserts which were welded in, jobs a good un, not sure if this is possible on a loop head tho.

Thanks Charlie, I now know what should be fitted and what could be fitted, that's really all I need. I'll start looking.
That sounds interesting Ian, I'd be happy to contact the seller if it's no use to you. Phil. |

I met a guy at Stafford Show who had a single V7 head for sale, not sure which side. Also a 4 speed gearbox. Can perhaps pass on details? I don't need either.

V700s and early Ambassadors had smaller valves, single valve springs and a long head head nut with o-rings to seal it at the "12 o'clock" position. Later heads all had the same valve sizes, but there were several changes to fin shape around the spark plug. Here are a few pertinent links: Tonti heads will fit and work, but since they attach the headpipe completely different (two studs vs. large nut) than Loops, you'd need to make up some sort of adapter.

With a bit of luck Phil, your question will attract the attention of "Ambo Man."
I think the 750 and 850 Loops have the same heads, but I await confirmation from Charlie. |

Good question, I"d be interested to know the answer to. I did look into this as spark plug helicoil died. In the end its been fixed but I may need to look again in future.
I think that the heads are different on different loop generations as valve sizes changed with capacity and probs other details but part numbers should help Identify whats what. Cheers |
