Just got it firing!
(Cross-posted to WildGuzzi.com)
Hi All:
Just obtained a beater LeMansIII clothed in T3 bodywork from the fairing back and oddly equipped with 2 left-hand PHM40s. Mileage is 90K. I'm hoping to build a vintage racer to superbike spec (rules in red, below) and run it in Washington Motorcycle Roadracing Assoc (WMRRA) events. I'm a Moto Guzzi newbie and have some questions for the racers, builders and experts on this board. Please comment on my off-the-cuff speculations that follow for best plan and cost-benefit:
(1) Engine - Bike comes with 1000cc jugs (SP1000?) combined with 850 LeMans heads. Keep this combo. Send heads to Mike Rich for dual plugs, rebuild and port job. Rebuild the short block locally. Timing Gears? Carillo Rods? Oil Cooler?
(2) Carbs - Dellorto PHM40s. Does the Keihin FCR41 kit for 1100Sport offer much benefit? Anyone have right-hand PHM 40 to trade or sell? Please PM me.
(3) Race Rubber - Are the Avon AM22 and AM23 the only option for the stock LM III's 18" wheels?? Options for race slicks??
(4) Front-end / Swingarm swap - SV650 front-end swap with RaceTech emulators or FZR same. Will an LM IV swingarm bolt on to allow 18X130 section tire??
(5) Bodywork - Anyone have LM III tank, seat, tail and fender for sale?? Please PM me.
(6) Fabrication - Please recommend bike-friendly machinist and fabricators in Seatle area.
Sorry for long post. Your collective expertise much appreciated.

5. Classic Superbike class regulations.
a. Includes model years 1973 through 1985.
b. The classes consist of:
I. Lightweight Classic Superbike (up to 550cc)
II. Classic Superbike (up to 1025cc)
The intent of the reintroduction of this class is to replicate the AMA Superbike class from 1976 through 1982. Participants are encouraged to build machines in the spirit of that series. Tubular handlebars only unless the machine came with clipons stock. No aftermarket fairings – only bikes that came with fairings stock should have a fairing, and it should be a silhouette of the OEM fairing (Suzuki GS1000S, Kawasaki KZ1000R, Ducati 900SS, Moto Guzzi LeMans, BMW R90S, Suzuki Katana). Machines should retain the stock seat bases, headlight shells and fenders as required in the series. Displacement should be 1025cc max.
Actual reproductions of specific period machines are strongly encouraged, including removing and rewelding steering heads to change steering head angle ala Wes Cooley and Reg Pridmore’s bikes, frame bracing of the era, reproductions of Calfab swingarms, etc.
47
As a concession to the lack of race rubber in 18” sizes, changing to 17” wheels (including changing front forks/triple clamps) is allowed/encouraged. Forks should look of the era – ie no upside down forks. For instance – SV650 wheels/forks/brakes fit on GS1000s with very minor modifications.
c. Engines must be air cooled.
d. Rear suspension must be twin shock.
6. General vintage regulations: applies to all vintage and classic superbike classes.
a. Modifications may be carried out to upgrade a motorcycle to period specification only. No components are allowed that fall outside of the era of the class.
b. Downgrading of racing machines is not permitted.
