|Charlie Edmunds is probably now one of the best know racers in recent BSSO history, taking not only his group 4 class win, but also the overall championship back to back for six consecutive years. Charlie Edmunds was overall BSSO champion for 2006, 2007, 2008 & 2009, 2010 and his final year 2011.|
Charlie has over the past seven years of racing, designed and developed many parts that are open sold through Cambridge Lambretta and Performance tuning, and also brought to the scooter scene products already out there in the kart and motorcycle world. Most importantly over the years we have been able to test to the maximum many of the products CLW sell, if Charlie cannot break it racing, then its good enough for us to sell!
|With Charlie retiring in 2011, the following year we sponsored our friend James Campen, also from the Performance Tuning race team. Once again as with his team mate before him, James managed to win his class outright, 7 years of Team Performance Tuning wins|
We stumbled across the sport of motor sprinting quite a few years ago, but never really thought much of it, until one day at a local meeting in Waterbeach just outside Cambridge we entered two of our scooters for a bit of fun and something to do on a Sunday! Needless to say once we had a go, we found it fun, so decided to have a go "properly" for the next season, as the one we had entered was the last meet of the year.
Fast forward to 2005, and plans for a fully blown sprint bike we as ever well behind schedule as the workshop is always busy. Not to be deterred, we set about using some of our demonstrator scooters to enjoy the fun any how. These scooters are normal road going scooters, used for rallies, riding to the shops, customers trying out the kits we sell, and all round general use, our Imola even goes down the 1/4 mile with a rear backrest, spare wheel and inside leg shield tool box full of tools! Our intentions with these scooters are not to try set or beat records, but to show that normal road going Lambrettas with the small block Imola engines can be fast, fun and reliable!
In 2005 we only managed to enter two events, we got off to a good start entering the first two events, and then Euro Lambretta and work over load took over. Needless to say we had a little fun, with the best times being achieved as follows. Peter Bowden, Imola sprint, 16.68 seconds with a terminal speed of 73.16mph gaining a first place and trophy at Wattisham, and Trevor Peat at the same meeting recorded 17.09 seconds, and 72.77mph.

The Monza 240 features a ported Monza kit, 62mm stroke crank, hand built expansion, 30mm PHBH power jet carb, Varitronic ignition. The frame has been stretched by two inches, light weight fuel tank, and a few other toys added. In the first season we achieved 13.27 with a terminal of 97.50mph. On a local dyno, the power output was 29bhp, at a run of 110mph, which of course will be less on the track, but it was geared and expected it to be near the 100pmh mark.
Futher tuning and a new expansion built in September saw results on a differing dyno as follows. As original spec 26.5bhp (shows how different dynos can give very different readings), after more porting work and new expansion power at the rear wheel now reads 37bhp. Coupled with a change of gearbox, the sprinter is now very reliable, with a gearbox and clutch basket (supplied by another shop!!) being the only failures.
Work for the new season will concentrate on weight loss.
