Hi Brian, just got back from Revival Scooters where I had my bike set up on the dyno and I am well happy. Here goes; it is an LML 150 (PX 150) motor, standard apart from; Simonini pipe, 26mm SI carb with all the jets that it came with (120 main, air screw all the way in then back 1 and a half turns, all the others as it came) timing set between 1 to 1 and a half degrees retarded (did it by eye so not sure on exact figure). It was running fine upto 80/85kmh then started spluttering upto 95kmh. The first dyno run showed it was too rich and only making 8.7bhp at peak power, but because of the stuttering and coughing it was only really usable at around 7bhp, the timing and jetting were actually about perfect but the problem was the Indian standard airfilter (it was too restricted by the amount of gauze in it, when you hold it to a light you cannot see through it, it is so thick) so they took off the filter and it ran like a different bike, they found me a second hand Italian filter, and fitted it, and it ran cleanly right through the rev range and made peak usable power of 10.1bhp at 68.7mph (about 115kmh). On the way home I was doing 100 to 110kmh into a strong headwind and it went off the clock at 120kmh on a clear level road sheltered from the wind. They told me that the LML barrel ports are smaller than Italian ones to restrict the performance, so that will be my next step, but I am going to try it as it is for a while to see what the improvement is and finish running it in ( this was dyno
d at 1184km so I still have 800km to finish running her in). They showed me a demonstrator of a PX 125 with a Malossi 166 kit, 26mm SI carb and Simonini pipe (basically the same stuff as I already have but with the 166 kit on) and they dynod that to 17.4bhp and it is still a reliable tourer as they have built it for road use, not as an out and out racer. MMM christmas is coming so I may be tempted. Basically, I now have a restricted 150 motor that is putting out the same power as a standard PX 200, just by sorting the carb and pipe.
