Hi All
Funny the subject of fuel additives has sprung up.
I have just got home from a mates place on my old 1939 BSA M21 sidevalve.(600cc) The old girl gets a snort of "flashlube" to keep the lead around the valve stems and a drink of standard Cats pee unleaded most of the time.
On birthdays and anniversaries i might shout it a schooner of Optimax and in return it does 45mph instead of 40
.
On the way out today the old girl felt a bit listless and sluggish ( standard performance for a war model BSA. The mate has an engineering shop and is a brillant machinist as well as hav9ing years of experience ringing every last ounce of HP out of tiddlers like BSA Bantam 125cc two strokes. His 1952 race bike boasts a yamaha crank and a 6 speed g/box replaces the old 3 speed bsa item. Top speed in excess of 100MPH ( with tobacco tins for brakes)
. revs to over 10,000rpm as opposed to the standard Birmingham Small Arms (BSA)
product disintergrating at anything over 2000rpm
We where discussing secret reciepes for fuel additives and he walked into the shed then returned with a black drum marked "Inflammable liquids 3"as well as producing a syringe.
It was about now i started thinking of taking the old darling outta his yard before it was introduced to drugs. Anyway ... like all good drug dealers he asured me that old BSA would enjoy the "Trip".
He then asked how much fuel was in the tank and i replied about 1 gallon . "When ya ride old bikes ya gotta talk in the old money folks".
He sucked up around 3 or 4cc of this strange clear liquid and found a vien in the M21.
Closed the lid on the tank and said go for a run. I pulled on the helmet adjusted the goggles and headed out of the yard not knowing what to expect. Well....... I almost got the front wheel off the ground.... anyone that has ridden one of these old clunkers will tell ya that is an impossibility.
I wrestled with the beast and its new found steroid performsnce all the way home. almost overtook a police car!!! Smoke and flame from the exhaust heralded my arrival back in the neighbourhood. It took 2 minutes after i tried to stall the motor for silence to fall upon the Reddo shed of invention.
Never... I repeat ... never... have i found perfomance in a bottle like the stuff the mate needled old betsy BSA with.
I rang him to enquire what was in the magic potion.....
Answer: Acetone.
;D
Hmmmm... i am sure all you fibreglassers are familiar with this stuff.
I called back around and he gave me a table of mixture/ratios. i am gunna by a 44 gallon drum of the stuff and head for the nostalgia drags....
So ther ya have it... now i have a drug dependant BSA as well as an alcoholic cat and dog .
So there ya have it Chippy Dave
500 HP 1200cc Coronas ....... definitely achievable.
Redd-Oh what a feeling... Tooooooyyyoootttaa
