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.

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.

engine revving really high

Hi guys. Newbie to the Suzuki world here.

I have a gsx1100 that I have bought as a surprise for my dad on his birthday but the guy before me had pretty much turned it into a rat.

Its now mostly back to standard guise and I'm happy with the way it looks but one thing is puzzling me.

When I bought the bike it rode fine and had no issues.

But now as soon as the engine starts the revs race as high as they can and I cannot work out why. I can't adjust anything whilst it is running as I pretty much need to shut off the ignition as soon as it fires up.

Most of what I altered was getting the stock fairing back to its original colouring and refitted and other minor cosmetic alterations. The only other things were a new front brake master cylinder (I had to wire the new switch in), changing the indicators back to stock, giving the bike a service, refitting the original handlebars and headlight and changing the battery. Other than that I haven't really altered much.

I'm at a loss where to look. The choke and throttle cable appear to be operating fully and smoothly and all electrics are working without issue as far as I can tell.

Does anyone have any ideas where to look as my dad flys out here in a month and I have very little time between studying and working to troubleshoot blindly. Last thing I want to do is resort to a dealer and pay for something I'm sure I'll be able to fix myself if I have the time.

Thanks for any help you guys can offer.
 
Sounds like something is preventing the throttles closing fully. Not sure about the layout on that bike but clutch cables can prevent throttles closing especially ones routed down between the intake boots. Some will have wire clips on the back of the head to keep the clutch cable away from the throttle sector.

When you fitted other handlebars, maybe the throttle cable is now under tension. Check that there is enough slack in the cable. Also check that revs do not increase when turning handlebars to left or right, indicating that cable is too tight.
