Dyno?

[John]

Are there any around Reading? Also how much do they cost?

Would like to see how many horses they shoved into the little AR.

Thanks

There is one at PDQ;

Hitcham Road
Taplow
Berkshire

And I believe there's a place in Wokingham or Woodley... called something like ridiculous horsepower bikes... Oh I can't remember...
Some of you guys went to a horsepower shootout where they won it.
Its gone. Its the early starts I tell you!

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

I've remembered now, with the aid of Google.
Wokingham.
I'd imagine that they have a Dyno

Thats the only two I know of - and they're not really in Reading as such. Hope this helps.

I'm sorry I haven't a clue how much they cost.

Big CC do indeed have a dyno.

Why do you want to put the AR on a dyno though? Not being harsh, but I don't think they'll take you seriously. They didn't let Zim put his SR on there

Hitcham Road
Taplow

right near where i got my mini from, weird

We actually had our very own dyno day at big cc at the start of the summer.

hi John,
just wondering what spec your AR125 is, if it is a full power (A) version or a 12bhp (B) restricted version. Many restricted AR125's have been partly de-restricted in various ways by previous owners, but i have seen performance bikes test figures for a full power A version, at 19.3bhp at the wheel. I think thats about 23bhp at the crank. A 12bhp AR would probably have around 10bhp at the wheel. It is difficult to de-restrict the AR sucessfully as nearly all the engine components, and specs were different on the 2 versions, probably because it doesn't have a power valve, so it cant be de-restricted that way, and also because kawasaki didn't want to ruin its performance and fuel economy by stuffing the inlet and exhaust with big washers, as is commonly done on alot of 12bhp 2 strokes. I saw a dynochart once for an AR that had had a stan stephens tune, and a Nikon pipe that peaked at 29,7bhp at the wheel, and with such a sharp powerband, that i bet it would make it interesting to say the least, to ride, especially with those thin forks, and tyres!

Mine's a B6, as per siggy

I'm guessing it's partly de-restricted, as with my 97.5 main jet it does an indicated 60mph in around 8 seconds.

Dropped it to a 95 and it pulls away much easier, but the power isn't quite as sharp when it comes in.

I'd still like to see it on the dyno.

When I first had the bike it was a fair bit quicker again, but pulling off was so hard it'd stall constantly. Not sure what the differences were exactly, though it had no airbox at all before, and the carb needle had be soldered up to let more fuel in.

I know that it probably did seem a little faster than it was when it was newer to me, but the acceleration in second was very very quick. I think it takes around a second more to hit the redline in 2nd gear now. One other thing I noticed was that I was able to hit 70mph around half way down a short road by my house on my first real go on the bike, now using the entire road and revving the tits off it I can only hit 75 before I had to slow down for the lights.

Kind of wish it was that quick again, but at least I can pull away now

Im not sure about the restricted versions jetting, but the A version used a 26mm instead of 24mm carb with a 92.5 main jet. I have heard that its possible to bore the 24mm carb to 26mm and fit the jets as listed for the full power version. If your bike can reach 75-80mph, and has a 0-60mph of 8 sec roughly then its got to be partly de-restricted/tuned, so maybe you might see around 15-16bhp at the wheel on a Dyno.
