Question about 2001 Suzuki GSX-R 750

Open Question

My 2002 GSXR750 is bogging down only when the throttle is twisted rapidly. The FI light is on and is showing a C28 code. The bike has an aftermarket exhaust, if that matters... Also, after installing a PowerCommander the bike is doing the same thing.

Who jetted it? Sounds like an air leak. Check your manifold.

SOURCE: How do I check the STVA on my gsxr 600 K1 as code

It is indicating a mismatch with either the secondary butterfly, the actuator or the sensor. The easy fix is to buy a second-hand throttle body from a wrecker and install that. The long and expensive answer is to buy a new TB ($1000, near enough). Alternatively, 'fix' the secondary butterfly in the open position and live with it.

if this bike is carbureted i would say your main jets are plugged.

Sounds like the jets are clogged in the carburetor. Try running some carburetor cleaner through it first. If that doesn't help then you will need to have the carburetor rebuilt. Hope this helps. Good luck.

I have a 2003 Suzuki TL1000R. It was running fine, then I stopped for gas. When I tried to start it, it would only turn over slowly, but would not fire, and the little F1 light came on. Help??


Open your rear seat and you'll see a black cap covering a connector/harness on the left side of the seat. If you take the cap off, you'll see it appears to be a normal harness. With your key in the ignition and bike turned to "on" (but not running), take a paperclip and short the two connectors out (by touching the two contacts together). This is known as a "ghetto dealer mode switch". It should display the error code on your display instead of just FI now.

I have a 2004 gxsr 1000 with fault code c42. It wont start. oil light is flashing and displays FI on the temp. Bike just crank but will not fire it up. Help?


Grab a paperclip.

Place the bike in Neutral, and take the rear seat cowling off. On the side of the bike between the tail section and the trunk you will find a connector that is covered by a rubber cap, and has two wires running into it. Remove the cap and take note of which one of the 4 sockets the two wires go to. Turn the bike ON and start it up, short the wires out with the paperclip. Where your speedo was flashing a -CHEC- with the temp should now be a CXX error code. Write this code down. Then shut the bike off. Match the code up with the list below. Grab a Manual and get to work!

(What you have just done is put the bike into "Dealer Mode".

05 gsxr stva has no power to it


Hi, Try replacing the sparkplugs with new ones and make sure it has the right gap. You can get them at your local motorbike shops. If the plugs are bad the bike will run poorly and sluggish. Good luck.

F1 code on my 2006 suzuki gsxr. it just started an 2 hrs ago drove it home in 20 degree weather now f1 code and no start


When the red light comes on, eg (F1) use these fault codes to find your problem. To extract the codes from the computer system, there is a two pinned connector hanging out of the wiring harness, on the left hand rear of the bike, (say above the pillion foot peg under rear trim. Be sure not to confuse the other connector used by the Suzuki Workshop Mechanics, as this has four or five wires to the connector) After locating the one with only two wires at the back, use a split pin or paper clip to bridge the two wires togeather and turn the ignition to the ON position. You should now be able to read the code on the console. The fault codes are as follows,,

Yes have 2006 gsxr 600 it flashs F1 will not crank


there is a plug under your seat with 2 wires that you need to short out. The fI code is a dealer code like a check engine light on your car. You need the actual problem code. turn the bike on and keep it running short out the two wires in a white harness under your seat and then the f1 will change to a C## code.
