model: 750 S3
frame number: VK2 15007
notes: Tomas's S3 is particularly interesting - Tomas: "My engine has gone through a major rebuilding. 94mm Venolia pistons with a stock crank gives 971cc, Norris RR3 cam, 11.1:1 compression, only 44mm intake valves, lightened flywheel and now a pair of PHM 40 taken up to 42.5mm by Malossi. Runs very well, just have to get the carbs tuned."
