Make sure your air filter is clean, check the fuel filter and tank for contaminants.
More off the wall , the rev limiter may be faulty, is it a certain speed or a given rev range that causes the shutdown?
Look at the air filter first!!
Good Luck, Marshall

get it to a dealer.quick

Without a good knowledge of the bikes wiring you could fry the ignition system if you try.

Your best bet is to get the new ignition cylnder from a junk yard or Suzuki dealer.

I hope you made sure the bike wasn't on the hot sheet before you bought it! Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

When this happened with my bike, I took a large gem clip, straightened it out, and then put a 90 degree bend about 1/4" from one end. I could insert the end with the bend under the seat and use it to grab the release mechanism and pull it so the rear seat released. Then I was able to connect the cable from the latch/lock correctly to avoid the same prob when the seat was reattached.

check spark plugs,check for spark. check fuel is good. possible needle and seat gummed up in carb float bowl. disasemble and clean with brake or carb cleaner.do not change float level. re assemble ,you can use the cleaner to help to fire the motor with a shot through the carb. make sure you cleaner says flammable. good luck.

Try charging your battery fully .idle running will take too long to charge the battery .Leaving your bike ticking over will not harm it oproviding it is not getting too hot through no air passing over the finning on the engine .

Make sure bike is upright, fully supported and weight of the front wheel, you will need say 50CM min clearance below to remove forks. Remove calipers from discs (two bolts attaching to each fork), remove front wheel (two bolts on bottom of each fork then wheel spindle), remove fender/mudguard (possibly four bolts), Undo the bolts that hold the forks into the lower yoke/triple clamp, undo the upper yoke/triple clamp bolt to remove fork (one side at a time) refitting is reverse of removal, enjoy.

Fi is fuel injection. could be a fuel pump or a sensor

charge the battery...see if it holds charge....if not get a new battery

You need a manual, there is a wiring diag available at:

http://www.carlsalter.com/motorcycle-manuals.asp ,

What you have is a lose connection some where, it is most probably an earth. Just fossick around and check all the ones around the items including the prug ins.

not sure of the Values on this engine, but anything over 100psi is good , a high variation between cylinders indicate a problem with that cylinder but thats not always something bad . a leak down test will locate the problem further if needed..

THERE SHOULD BE THREE BLADE TERMINALS ON THE BULB. ONE IN THE CENTER AT THE TOP AND TWO LOWER ONES. THE TOP WILL BE HORIZONTAL AND LOWER LEFT AND RIGHT WILL BE PERPENDICULAR.

Hi there ... is Reg/Rec the regulator and the rectifier? Based on your remarks, I will presume you have tested both the regulator and the rectifier and know how they both work.

Do this, my friend. Disconnect the hot side of the battery and put a amp meter in line with it. That will show any draw you may have. If there is a draw, remove all fuses and observe the load. It should go to zero. Be mindful, some systems are portected by circuit breaker - unplug them. One by one, replace the fuses as you observe the load. If/when it changes, you have found your drain.

There is that possibility that your battery is nearing the end of its useful life and not able to hold a charge.

Even though you have checked the rectifier, check it again, both sides and both ways.

Let me know how you make out, my friend.

a

Clean carburators, most likely has gummed up jets, don't blow out the jets without removing them first and even then sometime to remove all the **** you will still have to use something like a torch tip cleaner to do a good job.

Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part and/or the notation "Not Available" is in the description, the part is not in stock. www.babbittsonline.com/pages/parts/viewbybrandand/parts.aspx

Could you take a moment and rate my answer? Thanks!

FI means Fuel Injection. The computer chip that controls the fuel injection system on your bike has detected a problem. It could be major or minor. You will need to take the bike to a dealer and have them read the codes to find out exactly what the problem(s) is.
Can I get a “very helpful” rating on this answer?

it's not an F1 light it's an FI light for fuel injection. is it a full exhaust installed on the bike or just a slip on? may need a power commander to balance it all out.

that is the code for when a bike is laid down .... auto shut off sensor ...... as soon as u turn key off and back on it should be good to go again. ....

Check the main fuse in the starter relay that is under the seat. the battery positive cable runs to it.

sounds like you need to have your carbs balanced, also check the vacume pipe for perishing.
