    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.

Where is the power band on a stock 80gs1000e

80gs1000e

Just curious, at what rpm does my stock 80gs1000e make the most power and at what rpm should I shift if under heavy acceleration? Anybody know?
 
Just my opinion. For the best quarter mile times, The stock cam settings, on most GS's, like for the bike to be shifted a couple of hundred rpm. past redline. I'm not recommending it, just telling what worked for me 20 years ago.
 
If peak power is at 8000rpm and peak torque is at 6500rpm then shift between the two points, closer to 8000 if pushing it.

No, if peak power is at 8000rpm then you need to shift above that, if you don't then you'll be bogging in the next gear. How much above depends on the individual gear ratios.
 
Hmmm...... thanks for the info, I cannot remember where the redline is from memory on the actual tach display. I think while experimenting that I felt the power rush start to let off the closer to the redline I got. I thought that perhaps it was fuel starvation but carbs were just totally cleaned and synched. The max torque being at 6,500 would explain why I felt it let off just as I get closer to that redzone around 8,000 right?

I will experiment some more tonight. Shifting between the 6,500 and 8,000 and also after 8,000. :-k
 
You will definitely feel acceleration fall off after peak torque. The issue however is that power continues to increase through peak hp. Only when engine speed crosses peak hp do you reach a point where a decrease in engine speed (increase in gearing) would provide greater acceleration than the gearing you're currently applying. However, for some distance above peak hp, the amount that it decreases with increasing rpm will be less than the amount you will gain by jumping to the next gear. A closer gear spacing will allow you to shift sooner after peak hp than wider gear spacing.

OK, so I just reread that and it's not written well at all. Not sure how to explain it better though?
