Hey Barferz,
I thought there might be a Guzzista out here who might like to see some pics from a '73 Guzzi V7 Sport rebuild. The intention of this effort was to capture the 750cc P-PP class land speed record. So... it's a work in progress.
Starting off. I bought the V7 Sport as a basket case on Ebay 9 years ago and it sat in various places around the house for 8 years... dissasembled.
The frame had some ughly spots:
I dunno what that was all about. Moto-Italiano shopped out the reweld. After cleanup and paint the frame turned out beautiful in red.
The engine was salvageable. Here's the timing chest with early drive gears. Later in the next production year, in the Eldorado, Guzzi went to a timing chain with a notoriously dissintagratable tensioner. I feel pretty confident that these gears will last the life of the bike. Timing is a breeze and the marks don't dance as they can with the timing chain (in my Eldo).
Here is the chest later:
The heads were workeable as well. Little did I know that I installed a problem in this step that was to bite me later. Here is one of the heads as recieved.
Here is the crank with con rods:
Here's the trans. Gears look OK. Shimming is always a pain to me. I still need to fine tune 3rd gear.
Gotta true the wheels:
After buffing the brass nipples, lacquer looks nice but I don't think I'll do that again. It's a lot of work and the lacquer comes off when the rim is trued:
So anyway... I got the engine assembled for a base test. All stock. New pistons, rings etc. Valves by Gromm. Looks OK.
So I go to the Dyno and get an very uninspiring 40HP. I had another set of heads with better valves (?). While swapping them out I noticed media from media blasting in the bushings for the rocker pivot pins!!!! #$%^&*(*
Engine out and appart. Scrub clean, new oil pump, new rod bearings, all new seals and gaskets. Mains escaped unscathed fortunately.
More pics later if you like.
