Description
The time has come for me to sell my much-loved 1976 Moto Guzzi Café Racer, affectionately named Loretta.
I am a motorcyclist of over 30 years, and tend to gravitate to BMW and Guzzi bikes. Professionally, I am an Industrial Designer. I love to work with my hands, and have accumulated a set of tools and skills that would rival all but the finest boutique motorcycle customizers. This project has been ongoing over the last five years or so, never with an eye towards cost, but rather I have attempted to create the Guzzi I always wanted. Because of my job, I have fairly high construction standards. If I didn't like the way something was going, I simply rebuilt it until I was satisfied. I have a bit of an obsessive streak, and I went to some lengths to find parts and pieces which I thought embodied a character that was uniquely Guzzi. Specifically, I have combined parts and features from three iconic roadster models, the V7 Sport, Le Mans 1, and 1000S. Some parts are quite difficult to source. In the case of the handlebars, I found what was almost certainly the last set in the US. The carbs are special: the almost unobtainable “crank-top” Dell Ortos required a full year daily searching. I finally found them on the German eBay. Likewise the original seat pan took a year to find, and the V7 Sport style rear fender took the first five months of this year to source. Loretta was purchased as a derelict Convert. Beaten-up and missing parts, she had accumulated an impressive 88,000 miles. Apparently, the owner had died and she hadn't run in 20 years. Some fettling got her running, but also revealed she was almost completely worn out. With the exception of the rims and spokes, every single nut, washer, bolt, wire, stamping and casting has been disassembled, obsessively cleaned, and reconditioned or upgraded. I've put about 1000 trouble-free miles on her since the rebuild. Parts listed below as “new” were new as of 2017. Parts listed as “NEW” were new this year. This is not a garage queen, but a daily driver. I will be continuing to add miles and tinker during this listing. She starts instantly hot or cold, idles well, keeps the battery charged, shifts better than most any vintage Guzzi you will ride, stops better than virtually any bike from the era, and has fully rebuilt and dialed-in suspension. But that is just the basics. What sets this bike apart from most custom Guzzi's is the drivetrain. Firstly, Loretta has been fitted with a RAM lightened flywheel and clutch. This modification alone completely changes the character of the engine. Secondly, I've gone through maybe a dozen jetting changes on the Dell Orto PHF 36 carbs, and these are now on the rich side of perfect. The “crank tops” on these carbs feature a mechanism that opens the throttle slide faster than the twist-grip turns. Also keep in mind that these carbs are fitted with accelerator pumps, giving a very urgent engine response to relatively light throttle blips. The engine also has a “torque” camshaft from HMB Guzzi in Germany, as well as new valves, new seats, racing valve springs and full top end reconditioning from Bombar's Beemers. Air enters through a beautiful set of CNC turned aluminum velocity stacks also from HMB Guzzi, and spent gasses exit through a stainless Mistral exhaust system. The heads on the Convert are the “small valve”, and the piston are the larger diameter on the standard stroke, giving 995cc of displacement. This combination produces a lot of instantaneous torque. She revs eagerly to the redline. No pops, no backfires, just a happy engine. This is NOT your typical slow-revving tractor motor. I spent a great deal of time optimizing the gearbox, replacing all the bearings, gaskets, seals, main shaft, and fasteners. Perhaps more importantly, I spent several hours shimming the clearances until they were on the tight side of perfect. The result is a box that shifts easily and quietly. Rarely a missed shift. Never a false neutral. But the best part is the low-ratio rear drive. I purchased the gearset through Stein-Dinse in Germany, and took my time installing it, having ordered a complete set of shims to make sure the ring and pinion gears were properly aligned. And once I put a hundred miles on it, I took the time to remove, disassemble and inspect the wear pattern, only to find the setup was perfect. What's it like to ride? Compared to the stock '76 BMW R90/6 I had in my garage last week, piloting Loretta is akin to driving around a big-block Nova with a 4.11rear end. This torque-monster engine, light clutch, pumper carbs, slick transmission, and low ratio rear drive is far more sprinter than tourer. Though it is happy to chuff around in top gear at 30mph, it is practically begging you shift down, open the throttle and bask in the glory of its barbaric exhaust yalp, unmuffled intake moan, and (for the time) brutal acceleration. Pure smiles. The other side of riding Loretta is a bit like dating a Supermodel. People stare at you. Folks stop you at the gas station. Going to hardware store invariably means a conversation with an admirer. You do get used to it. I've started the listing at considerably less than I've spent in parts alone, not counting the cost of the original bike.

It was cut and welded to fit the long tank, then powder coated. Finally it was sent to Sargent Cycle in Florida to add the upholstery. This “dual seat” was made specifically so I could take my daughter for ice cream. Also there is a single “café” seat that goes with the bike. It is from Radical Guzzi in Germany. I rode it with the single seat for about two years, before practicality won out. It is significantly less comfortable for my 49 year old body with replacement hip. But it looks cool. I've included a photo with this seat sitting on the frame.

The carbs are a matched set of vintage Dell Orto PHF 36's. I mistakenly labeled them at PHM 38's above.
The front brake calipers are Brembo F08, NOT F09. This will be an important distinction to some.
This bike is equipped with electronic ignition. I believe it is a Dyna III system, which was purchased new. What is important to note is how well the ignition is timed. Guzzi flywheel ignition stampings are notoriously vaguely placed. The only proper way is to find TDC for each cylinder via a tool made from a lengthened sparkplug and a degree-wheel. The evening I timed this thing, I was feeling especially obsessive, and I spent two full hours tweaking the timing on each cylinder until it was dean-nuts perfect. I could not have been off by more than a tenth of a degree. I haven't touched it since.
The horns are reproduction Italian units of the kind specified on Guzzi Converts. They were also purchased new, at considerable expense (for horns). This year, they have begun to sound a bit weak, so I will be replacing the horn relay before auction's end.
All other electronic functions and instruments work perfectly-- all switches, all indicator lamps, all lights.
Added the horn relay. Changed all fluids: front brake, rear brake, rear drive, transmission, engine oil, fork oil. Changed engine oil filter. She's ready to go!
