So I had my 650 dynoed this weekend.

Try to think of horsepower ratings as analogous to how many previous 'boyfriends' your girlfriend has had. It definitely effects performance, but do you really need to know the exact number? It might not make you happy.

This is classic LOL

my first bike I put on the dyno at M.M.I. phoenix was a CB 750 s o h c stock cam no porting 836 piston kit. this bike would get to 130 along with the 1000 sport bikes that my buddies had. not as quickly but still went ton up.

45 hp I did not get a torque spec-- I was soooo disappointed. but if 45 hp gets a ton on the speedo I figured hmmm... 100 horse will tear yer eyelids off.

Good info. Most people's HP expectations are unrealistic. I think it comes from comparing hyped up factory figures after doing additional mods, and they end up disappointed.

I had a FZR400RRSP a while back. This is a Jap import yamaha. I had it dynoed and it was rated at 54hp. It was a blast to ride but only topped out at about 130mph with my big arse on it. I then installed a YZF600 motor in the chassis and it was then cranking out 86 hp. Boy was it fast but I actually preferred the 400cc engine over the 600cc mill. With the smaller motor I could flog it everywhere and had no worries at all. I miss that bike.

when i bought my 1981 gs1100 e the motor was just rebuilt using a wisco 1 mil over kit , web cam ect ,,,, they had a dyno sheet that showed 127 hp . i thought this was a complete bs line from the builder . how much should a gs 1100 put out ?
my buell puts out 101 to 104 depending on weather but its got racing heads , pistons , cams , modual , supertrapp exhaust and carb work out the wassso
buell has to have 93 octane with a booster or it pings

Sonny, does the beull have aluminum heads?
My point is that aluminum disipates the heat faster and you can usually run 1 full point more compression with the same octane fuel than cast steel.

[sonnygs1100]

yes it has aluminum heads with bath tub cambers and piston match the same domed bath tub shape

[mpls-ugly]

Is it a L shaft drive? I would think that our shaft drive could eat that up along with age. Crazy to think this is 50hp, and feels fast to me. I agree about the perception of speed. It feels crazy fast to me on my buds 79 KZ1000 with fresh wisseco internals broken in this year, pods and a kerker pipe and then I ride another friends 04 Z1000 and that thing can hardly keep the front wheel on the ground but it dosnt really fell as fast. I think its something about the new fuel injected fours. Its cool in a totally different way. Just like going 80mph in a old MG or 140 in a New Audi.

how much should a gs 1100 put out ?

Pretty sure a stock GS1100 4V put out anywhere between 88-95 rear wheel HP, the the 80-81 were on the lower end of the range and the 83 model was the highest of the bunch since it had the bumped cam. Suzuki advertised the GS 1100's between 105-108 BHP.

Suzuki also claimed 90 BHP for the GS1000 2V models but when Cycle dynoed the original 1978 C model it only put out 72.5 rear wheel HP

The 83 1100E/ES, according to the sweet brochure from the showroom i have for it, as well as the factory service manual, states a BHP rating of 111.

Despite the more aggressive cams, the '83 produced identical hp figures to the EZ, depending on which mag you go by (I have the M'cycle Reports compilation that lists all the tests, but haven't looked at it in years now)...usually listed anywhere between 108 to 111 bhp (at the crank I'm assuming...which would put power at the wheel at less than 100) The benefit of the changes made to the airbox, cam etc. was mainly increased torque, IIRC.

Suzuki insiders have only recently revealed the real story.....painting that beautiful engine black for '83, inexplicably instantly resulted in lower hp figures across the board....engineers were sent scrambling to make subtle changes to find and restore the lost power, which they did, to their credit.

HAH! That paint is some heavy stuff eh?? LOL

Even heavier.....t'was thermodynamics at work, Josh.

Hrmmmmm Sounds really smart...But, i think we should test it

Rest assured, Posplayer will be along shortly, to shoot it down.
In reality, IIRC black engines actually have the advantage, in terms of shedding heat.
