Wal Philips was the pioneer of small cheap mechanical fuel injectors for scooters and light motorbikes, Vespa 150s, Lambretta 200 GTs and Enfield 200 cc 2-stroke (?)motorbikes Something for nothing - that's what everybody would like - a couple of magic words and suddely your bike develops another ten brake horpe power! This never happens and so you have to look around and decide just where your money is best spent. The answer is to improve the engine, but this usually means buying very expensive parts and also spending long weekends in stripdowns and testing. But we have found an item that you can buy and bolt on which will give a reasonable increase in performance, and that is a Wal Phillips fuel injector. M M has tried these out in the past and found them to be just as clean running and realible as a carburettor but correctly unied, they will give a higher top speed, increase acceleration and sometimes both. We had a pair of Lambrettas on test this month and this was an opportunity to try out a new injector designed specially for scooters. Made by the sane firm, this injector is similar to the existing types, but it is much shorter so that it can be fitted to a Lambretta or Vespa without having to cut a hole in the side panel. Having a stub fitting, is fitted straght on to the SX200 that we were trying out. The tubing which normally servers as an overflow pipe to the Dell'Orto carb can be used as a petrol pipe from the tap to the injector. Wal altered the adjustment very slightly and then the bike was tried out. These are the times that were recorded: | carburettor | injector | 0 - 30 | 5.5 sec. | 4.6 sec. | 0 - 50 | 14.5 sec. | 12.0 sec. | Maximum speed | 61 mph | 70 mph | I seem to remember my contemopraries were very underwehelmed and the word was keep the carb You'll need to refiy it. |
