Title: V7 cylinder bores
Post by: Dnaj on November 01, 2016, 10:22:39 AM
Anyone got a Gilardoni piston set and bores sitting on a shelf somewhere for a 700cc V7 they might part with? I know I can go the 750 route and turn down the sleeve but not sure I want to get into that. Looking to bring this one back to life sometime soon. It's been sitting since the mid-seventies.

Hi David,

My advice would be to have your original cylinders replated. If your pistons aren't reusable (damaged or worn beyond published specs.), buy a pair of these piston assemblies:

and then send them along with your cylinders to Millennium Technologies: http://www.mt-llc.com/ You basically end up with the same thing as Gilardoni kits at a comparable cost.

That's pretty darn interesting! Exactly why I posted the question here! This forum never ceases to amaze!

uuuuummmm, I'm fooled again. I look at that foto and see v750 Ambo, not the 700...I dont see the wonky 700 valve covers, but it is a left foot shift...don't see a 700 tank, but a later loop tank...SS carbs, not the later vhb...real mix of stuff, or was this a production bike?

It does appear to be a mix of parts - V7(00) and Ambassador - mostly the latter.

Its a late V7 according to the 4-digit vin. I can't really ascertain the history of the thing, shows 7000 miles and last run in the early 80s. The tank 750 fools me but the matching non-locking tool boxes make me think maybe a dealer swapped stuff around to get it off the floor after the larger Ambo came out. I've got nothing that says it was production other than the patina matches all around. I'm thinking dealer.
