I cant remember.... does the 05 have a "choke" lever? or is it automatic. On the 06 up bikes it is automatic.

also, does the rpm hang when you rev the bike before dropping back to idle?

 

My 02 750 had the automatic, so I would assume the 04-05's have it as well.

 

HUH?

My 03 600 had a choke lever........ and I thought the 750 was the same as the 600 01-03.

 

Well, I thought everything was the same between them too lol...but I'm 100% positive, mine had the automatic fast idle.

 

:dunno.... been to long ago now :lol

I am 100% positive my 03 had a fast idle lever . I adjusted it to act like a cruise control for some time :spit

Engine and more torque
Perhaps most impressive about the 2001 Gsxr 1000's power dominance is that it came from an engine virtually identical to the Gsxr 750's and, according to most tuners, in a fairly mild state of tune.
Suzuki moto chose to use as much of the Gsxr 750 as possible, so the Gsxr 1000's bore increase was limited to 1 mm.
The rest of the boost to 988 cc would have to come from stroke, which traditionally benefits torque production more than an increase in peak power.
The Gsxr 1000's 59 mm stroke was the longest in the class in 2001. What's more, Suzuki moto had the audacity to use the Gsxr 750's cylinder head essentially unchanged.

Common wisdom was that valves ideal for a Gsxr 750 would be prohibitively small for a Gsxr 1000 k1. Even the intake system was borrowed straight from the Gsxr 750, with some minor changes and the requisite computer reprogramming.
The servo that controlled the secondary throttle body was now mounted right to the throttle-body rack, not remotely as before. This change would come to the Gsxr 750 in 2002 along with an extremely clever fast-idle system. Before, there had been a small lever on the handlebar to raise the idle speed for starting.

 

looks like they bastardized the 600's on this addition

 

So to answer the OPs post, it is your fast idle, commonly refered to as a "choke"

It should not raise that high though, so it needs adjusting. Get a manual, and it is an easy fix :thumbup

 

Sounds like your high-idle screw is pushed in a bit. Try to loosen it a bit

 

it has a electric choke on it. no cable. Ive tried turning down the idle and it still does it.

 

'
Get a manual, there is a way to adjust the "choke" level as well.

 

how do you adjust an electric choke?

 

It is not an electric choke.

It is a fast idle. All it does is turn a cam that opens the throttle slightly basically. There is a screw to adjust that cam.

 

There's a second idle screw above the main idle screw. if you lift the tank and observe as you turn on the key, you'll see that second idle screw lightly open the throttle. That second idle screw that's moving all on it's own is the one you need to adjust

 

thanks for all the help guys ill check it out tomorrow

 

this may help
