Ever noticed how on some spec sheets the earlier GS500's are listed at 52hp and the later ones, like post 96 or so, are listed at 47hp?  Why is that?

Oh yea, the earlier ones were the best 89-95 made in japan, then in 96 they made them in mexico, and after 04 they are made out of mud and sticks 
Oh yea, all of them are monday morning assembly jobs, they come with lots of loose parts, with missing bolts, and some even have missing engines and wheels ... Needless to say they never put any real suspension parts in it by design, so you're usually good there ...  .
As soon as you buy it, you gotta replace 1/2 the bike, the next month, replace the other 1/2.
Then go for a ride.
Cool.

I've never seen a stock GS rated over 40hp.If you're finding this on line post the links.A stock GS don't make that much power even with upgrades.

96 made in Mexico?  Not according to the sticker on my 96, made 11/95.  Made in Japan.   

My '01 was 34HP at the wheel.

Oooooohhh.  So I have one of the LAST GOOD GS-E's right?  Man, I should charge more for it!   

I thought the latest Es and all the Fs were made in Spain.

What's up with this "reduced effect" version(27hp), here it's listed for 1991:

How do you tell them apart?

Could be a restricted "Learner special" with a reduced power output to cater for certain European markets and their laws.

dunno according to your own link, seems there are some differences of HP/Nm through the years.

1980 46 hp

1991 52 hp (38 kW)/ 9.200 rpm, 41 Nm (4.2 kg-m)/ 7.500 rpm.
1993 52 hp (38 kW)/ 9.200 rpm, 41 Nm (4.2 kg-m)/ 7.500 rpm.
1994 52 hp (38 kW)/ 9.200 rpm, 41 Nm (4.2 kg-m)/ 7.500 rpm.
1995 52 hp (38 kW)/ 9.200 rpm, 41 Nm (4.2 kg-m)/ 7.500 rpm.
1996 52 hp (38 kW)/ 9.200 rpm, 41 Nm (4.2 kg-m)/ 7.500 rpm.

1998 47 hp (34.3 kW)/ 9,200 rpm, 40 Nm/ 7,400 rpm.
1999 47 hp (34.3 kW)/ 9,200 rpm, 40 Nm/ 7,400 rpm
2000 47 hp (34.3 kW)/ 9,200 rpm, 40 Nm/ 7,400 rpm

2001 47,7 hp (35,1 kW)/ 9.200 rpm, 40,2 Nm/ 7.500 rpm

2002 47 hp (34.3 kW)/ 9,200 rpm, 40 Nm/ 7,400 rpm
2003 47 hp (34.3 kW)/ 9,200 rpm, 40 Nm/ 7,400 rpm

hahahahaaha!  My GS has more power than your GS's!   





When did they change the stock jet sizes?  Wasn't it beginning in '97?

My crappy 'n shiny '08 was made in Spain, where the rain falls mainly upon the plane.

I believe its MOM noted something in the neighborhood of 40+ horses, but I bet the torque curve looks a loy like Pike's Peak at about 6,000 to 7,000 revs

My bike don't make no 47 to 52hp with rejet,K&N lunchbox,and D&D exhaust.My engine is in top condition.  39-40hp I could see but 47+.

isnt that rating also at the crank with 0 miles? under prime conditions?



and that chart is missing my 1990!!!

you realize that 47HP is calculated as engine on a rack, measuring the output on the shaft with no load on it..
so on a wheel dynowith a rider, I would expect anywhere between  38-45HP is probably your "on the ground HP"
there is a huge amount of losses in power once assembled, vibrations of engine in bike assembly, transmission, clutches, chain, gears etc all are a part in losses in power before it actually hits the pavement.

Yea I know about drive line losses,but even on an engine dyno I don't think my bike is making 40 hp at the crank.I've built enough engines to know my engine is weak.

one mans weak is another mans busa
