I own a 1990 gsxr 1100 when I turn ignition key on turn signals light up and bike will not start no power to anything . and there are times when I turn ignition key on headlight comes on like it is supposed to and it fires right up I never know when it is going to happen have no idea how to proceed have checked wires relays cant figure it out any help or advice on what to look for would be greatly appreciated

As I agree with the previous answer. I have found that if the bike in question sits outside in the rain a lot, the ignition switch on the handlebars seems to get corroded contacts on the inside causing a no start no crank situation.

Cant see why it wont fit as I think the frames are the same onlly the engine siz is different

cross threaded. needs to be tapped or dyed

Vl 800 Blvd c-50. F1. Bike won't start turns over but will not engage

Sounds like you have a short in the electrical system possibly around your fuze box. Best thing to do is to just pull off all your plastics and trace the electrical system, looking for exposed wires or damaged wires.

The usual reasons the fob doesn't disarm the security system is:
1) a damaged fob
2) discharged fob battery (Panasonic 2032 or equivalent)
3)electromagnetic interference
a. verify the fob in not in a metal enclosure or within 3" of any other electronic device.
b. place the fob on the seat, start motor and return fob to pocket.
c. move the bike at least 15' from the spot of interference.
With the Fob near the bike, try disabling the security system.

You'll need the PIN number.
If you don't know it, you'll have to change it to a 5 digit PIN number you select.

With the fob present, turn IGN switch:
IGNITION-OFF-IGNITION-OFF-IGNITION
Press LEFT turn signal switch 3 TIMES
Press RIGHT turn signal switch 1 TIME and release
Turn signals will flash 3 times. Current PIN will appear in odometer. The first digit will be flashing.

If changing PIN, enter first digit (a) of new PIN by pressing LEFT signal switch (a) time(s) i.e., for the number 1, press one time. for the number 5, press 5 times.

Press RIGHT signal switch 1 TIME and release.
the new digit (a) will replace the current in odometer window.

Enter second digit (b) with LEFT signal switch.

Repeat until PIN is set.

Once PIN is set (either new or old PIN), to disarm security system, DO NOT sit on seat, lift bike off kick stand, or anything else that will activate the security mode!

Turn IGN to IGNITION.

Quickly (within 2 seconds) hold BOTH turn signal switches until confirmation signal (KEY icon flashes at fast rate, in odometer window, a flashing "-" will be followed by 4 more dashes = "----")

Enter 1st digit (a) in PIN by pressing LEFT turn signal switch (a) times (i.e., 5 times for the number 5)
The 1st "-" will become the 1st digit (i.e., "5")

Press RIGHT switch signal 1 TIME.
The 1st digit is stored and the dash will flash.

Enter 2nd digit (b), and repeat sequence until done.

After the 5th digit is entered, the KEY icon stops blinking, and the system is disarmed.

The system will stay off until the IGN switch is turned off.

If at any time during disarming sequence an error is made, wait 2 minutes before trying again.

If you have a factory security system with the sensors located inside the key fobs you probably need to replace your fob battery.

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,,

the gsxr1100 cam will fit the bandit 1200 engine, i've done that mod 3 times so far. after that it's just exhaust and jetting.

No They are Different They Wont fit..
