hi I own a plunger a10 and use it in the summer to play on the back roads and out in the country side cant beat the sound of a a10 shutting down. not the kind of bike to buy if you want fast performance but in top gear will pull up a mountain without missing a beat. classic motorcycle at its best
On account of today...Merry Christmas! Really liked your video...it really shows that these ol' classics aren't just around to polish with a diaper...they're the real gimmick...a real riding machine. As far as horse power and travel, I've got a '72 Honda CB350 with way less ponies, and I go riding for days on end here in Ontario, Canada, -and you don't need all that power to get around...shoot, man! -Your on 2 wheels and unless you're a 500lb son of a gun, how much power do you need?
my a10 for an old bike its ok it was running well back then but it had been mesed with some serious high comp pistons and for an old bike it had some poke. i got fed up with the reliabily of it tryed to blowit up one day it got me mad but i put it to the back of the shed till i find time to rebuild it and calm it down so its more reliable. though my a10 is a pain i will sort it coz all my other bsa's ive sorted take me 1000's of miles across europe and uk. many thanks for ur coment
the road rocket sounds nice better in real life obviously i restored a A10 and using a old motor cycle guide timed it with a packet of rizzla papers ! and it started first kick the biggest enemy of the bikes are the capacitor in the end on the mag bobin
replace it with a tv capacitor and it gets the mag running well !
Beautiful bike, beautiful noise! I have a GS 500, which is 1980's air-cooled technology, and it has 47 HP, which is almost 1 HP per 10cc, as it is 487cc, but it's a DOHC twin, not a SOHC single. A 500cc air-cooled single will net you less, about 40 HP, which is what my friend had with his 1978 Yamaha SR 500, which strains to do 90 MPH. These are stock numbers, and you can't hot-rod a single very much because it will vibrate like crazy and be a pain to ride.
Bsa (and everyone else) used to exaggerate (read: lie) their hp ratings for sale profit. If my math is somewhat right this puts you around 29hp. Not bad. Srm says that the most they have seen on a highly tuned A10 is about 49, if I remember right.
If 40hp is 85%, it will be around 47 at the crank. That`s pretty good hp rating. My old 71 lightning got 24 at it`s best. After having a top end overhaul, checking timing, changing jets... I got tired of not finding
the fault and sold it.. By the way, I get my top A10 readings at about 85mph in third gear. Changing to fourth calms it down immidiately after hitting top rpm.
pistons, cam, big or small inlet valves, jets, timing and any mods ?
I Friend of mine got 23 rear wheel hp on his stock Golden Flash. I`ve heard that the loss though drivetrain is 10-15%, I guess Old bikes have more loss so 15% would probably be about right. Sorry to disappoint you but adding 20 is just not right after my experience.
39 horsepower ? ...dont think so bud...maybe 3.9 HP, if you get 1 horsepower per 10CC (cubic centimeters) you're doing pretty* good geed even by todays standards, especially if you want the motor to run for more than 5
Err, I think you'll find he meant the BIKE was a 1985 CCM - not the capacity (centimetre is spelled this way - metric system, not "meteric" therefore NOT centimeter). I don't know, what with George Bush and his NUKULAR, that Noah Webster's got a lot to answer for.
And "dialect" makes Nuclear, Nukular? I think old King George did the right thing after the Tea Party - we'll speak English, you speak god knows what.
but thats an expensive 125cc bike that may or may not last really long, this is very uncommon for a motor to be that strung out, plus it probably gets that amount of power at 15K rpm. if you wanted you could probably build an engine that will get 1hp per cc, the possiblities are endless with the technology we have nowadays, im just talking from a realistic/common perspective (yes the aprilla is reslistic, just not common)
Not too sure where you got your "loses" information, but that premiss mean that my old M20 BSA pulled a single seater sidecar at 48mph on about minus 8 to 10 hp. Something does not quite add up

This is a weird bike. Older engine with newer forks & brakes.

Hi, Nice Bike !
What is your setup?
pistons, cam, big or small inlet valves, jets, timing and any mods ?
I Friend of mine got 23 rear wheel hp on his stock Golden Flash. I`ve heard that the loss though drivetrain is 10-15%, I guess Old bikes have more loss so 15% would probably be about right. Sorry to disappoint you but adding 20 is just not right after my experience.

Centimetre is spelled with an "er" in America. It's a different dialect. Chill out.
