    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Running rich, I need some advice, please

Glad to hear it sounds like it's sorted... but make sure you get some miles on it before deciding to sell it or not... my 450 will be staying in my garage even when I get my next project... I just have too much fun on it to get rid of it!

Pete,

I just received a dyno chart showing the pull on the GS450S....40.5 HP at the rear wheel, totally stock. 36.5 ft/lbs torque. So the motor sounds healthy, I can't wait to try it! The mixture screw settings were the only modification. GS450SJIP

Nice! I'd like to get mine dyno'd one day but I'll get the tuning finished first then see how I go... it's not all that cheap so I'd like to make the most of it.

Be interesting how those figures compare to what Suzuki says they should be...

Pete,
Actually, 1 hour of dyno time is just under $100.00, at least here. I got a complete printout showing Horsepower, torque and Air-Fuel ratio throughout the RPM range..With stock airbox-filter, main and pilot jets etc, only a mixture setting change, the A/F ratio was right at 15:1. I am not at sea level, but close to it, and the temperature was about 30 degrees F during the test.
I think Suzuki rates the motor at 42 hp, I don't know if that's at the motor or rear wheel.

Cool, if I could get it for $100 I'd be laughin'.

One of the guys found out how much to get his brother's R6 on a dyno and it was $400! That may have included some tuning time though whereas I'm really just looking for what it puts out etc. and some AFR readings.

I'll finish with the mains and mixture screws then I might make a call or two.

And I'm pretty sure manufacturer spec's are at the crank too...
