BROQUET - Motor Cycles |
Indeed we have many reports from motor cyclists saying how much Broquet improved performance despite switching to a lower grade fuel - see below.
BSA M20 owner Simon Lowe commented, "Broquet has given my engine a new lease of life without the need for costly surgery", (Motoring & Leisure, September 1997).
Broquet is available in a wide range of sizes to suit all type of motor cycles both old and new - our oldest "customer" is a 1904 Ariel . Since Broquet improves the actual combustion process, engines run more coolly, because of better thermal efficiency, and with more available engine power.
This was summed up by Broquet user Alan Gidley running a 1938 water cooled BSA 1203 cc Scout when he reported
"When I first put Broquet in the petrol tank I almost immediately noticed that the engine began running very smoothly at tick over, whereas it had been very lumpily prior to that. l also noticed that there was a reduction in the engine running temperature of about 6'C at driving speeds, and as the B. S.A. employs a thermosyphon system, no water pump, this was an improvement over the previous 95'C running temperature."
In New Zealand Broquet is popular on racing circuits where Suzuki RCV 250 cc rider Richard Clapham wrote,
"It used to have a flat-spot at 9000-9500 rpm but now pulls through this area cleanly and smoothly in any gear; fifth or sixth would not accelerate at these revs previously. lt always pinked and stuttered in top gear between 60-80 km/h but is now smooth. Better pull up hills and heaps of mid-range power. Feels like a Grand Prix bike, heaps of grunt. " Writing in Triumph Motor Cycle Owners Club Magazine, "Nacelle ", 750 Bonneville rider Rick Hodge says,
"Not only does it accelerate and cruise better at high speeds, but it has also significantly reduced the pinking problems l had when the engine was under load. The real bonus, however, is the fact that l can run on either leaded or unleaded. "

David Baretto who now lives in South Africa, and the Triumph Tiger l00S of Stuart McFadyen who is a member of the Triumph Motorcycle Owners Club. Both motor- cycles are supposed to use only leaded petrol but thanks to Broquet are now happily running on unleaded petrol. |

Another very satisfied motor- cycle owner is Rick Hodge who fitted Broquet.. to his Triumph Bonneville . He was so pleased with the effect on the bike's performance that he wrote to the Triumph Motorcycle Owners Club magazine ` Nacelle ' stating that after fitting Broquet he found that his bike accelerated and cruised better, pinking was reduced and it started much easier, but the real bonus was that he could use either leaded or unleaded petrol. |
Getting the Max!Pictured here is the GSF6OOS Bandit motorcycle of Alex Johnstone. He wrote in to say since fitting Broquet he obtained a maximum of 64mpg with an average of 55mpg. Yet when tested by both Motor Cycle News and Ride Magazines the same model could only achieve the mid 50's with average of mid 40's. He finishes off by saying "I have no doubt that Broquet was the reason for the higher figures and I have just placed my order for my forth unit." |

Previously I've had many problems getting the carburation absolutely spot on, the engine snatches below 4000 rpm, and economy varies considerably depending on the fuel quality. Within 50 miles the catalyst gradually improved things. Results are like it has computer controlled injection rather than a carb. It pulls from 2000 rpm, power delivery is very smooth, the powerband is very broad so the engine is much more flexible, considerably more usable power and specifically more mid-range torque. Overtaking is much easier. At high altitudes, like any carb engine, it runs slightly rich, killing power delivery at low revs. This was made even worse by poor quality fuel. With the catalyst installed, the engine seems indifferent to altitude, behaving much the same as at sea level. I now find myself using a gear higher and have to change gear much less often. Fuel consumption has improved but I don't have exact figures yet; my guess is around 10 percent. This will mean more range between the few petrol stations in the mountains here as there is always fear I'll run out. Also at altitude any engine runs slightly hotter due to lower pressure. I noticed a definite improvement of around 5 deg C less on the gauge, which suggests better thermal efficiency so less wasted energy in the burn.
I was so pleased, I ordered one for my 1986 MZ 250 2-stroke single too, mainly to help smooth running and keep it decarboned. decarbonised. decarboned. After the first 50 miles I noted a gradual improvement. Now it ticks over smoothly instead of lumpily, revs higher, runs more smoothly and gives more power. Again I don't have exact fuel consumption figures, but it will be improved.
So basically, this catalyst does everything it says it does, and is like I have a different engine. Plus it looks like it'll pay for itself relatively quickly. Both vehicles are intended for unleaded.
I'll keep you posted on how it progresses, but I'm extremely satisfied.
Thanks for your help, Graham Elliott." June 2003
