1999 Suzuki GSX 750 F (Katana) - Answered Questions & Fixed issues

If your sensors are OK then I'd be checking the wiring for a short?

look for a lock washer that will have to be flattened to remove the nut.

ON OIL LEAKS IVE BEEN A CERTIFIED MECHANIC 40 years plus i have 2 issues to add yo fix ya they would be oil and gas leak issues gas leak can ruin motor my fix dissasemble fuel petcock remoce tiny o ring and spring carefully dril 2 more holes opposite 2 hole allready there dissconect vacum now add xtra t valve with manual cut off gasleak prblem fixed oil leaks if oil leak is persistant by that i mean you just see oil after sitting over nite minimum amount go to a hier i use 20/50 non syn thetic oil but live in so florida so it depends on owners location good luck signed suzuki750 owner

You may be lucky and it may be just a blown fuse ,if not it could have done serious damage to any power units .

Take off clutch lever. If it engages fully, check for a worn bearing in lever. Otherwise you have adjusted it improperly or the least possible cause, you did not install spring properly. If when lever is off and clutch still does not engage, remove cable from spring.If clutch engages you either have a faulty cable or somehow you have it bent to far or pinched it..

Put the battery on charge - while it is charging remove and clean the sparkplugs - once the plugs are clean and refitted also make sure all the HT leads are secure - check the fuses, have a once-over of all the connectors and cabling and make sure everything is dry and secure.
Likely the battery was never fully charged to begin with - but still clean the plugs since they will be fouled from the non-starting.

when purchasing a brand new battery usually you have to fill it with acid then you actually have to charge it, you just cant hook it up and go. after doing that double check the battery cables make sure it has a solid ground then i would check the fuse box and make sure all the fuses are good then i would check the ignition switch make sure nothing is grounding out. hope this helps

Bent or worn shifting forks most likely. not for the begginer....

no the bike wont run if leads are wrong. possible idle speed control or ECU problem

mate adjust clutch cable or if no difference replace clutch plates

I had this problem with my 900 Diverstion, the piston wouldn`t move and the pads weren`t in contact with the disc allowing it to rust. What I did was I got a thin screwdriver and dipped it into engine oil, placed the screwdriver over the slot between the caliper and piston (This minimses oil getting on the disc and pads) then I got some gas pliers and slowly pushed the piston back, Make sure you do this evenly by moving the pliers around pushing on different parts of the piston so that it goes back into the caliper straight or you`ll damage both the piston and caliper. I repeated the numerous times by pressing the brake lever, this brought the piston back out. Keep an eye on the brake fluid level andDon`t let it come out too far or you`ll have a hell of a job getting the piston back in to the caliper and then you`ll have replace the seals and you`ll have to bleed the system. If your bike is like mine with a double front disc, only remove one caliper at a time because you`ll push the piston out of the other caliper as well. I did this about 12 months ago, I`ve had no problems since and it`s passed an MOT since. I hope this helps. Ian

needs the carbs cleaned out, and possibly some new spark plugs. If it has been over 4K since the plugs were changed, they need replacing also.

Good possibility, You can check the out put voltage of the pickup coil. This has to be done with a "peak reading volt meter". There are some commercially available adaptors to insert in a standard volt meter for this check. With adapter installed, meter set to DC volts the reading across the leads from the pick up coil should be 3-7 volts at cranking speed. You should also confirm that you have battery voltage with the key & engine stop switch on at the cdi box as well as a good ground. I believe on a Suzuki this will be the orange/ white for battery voltage and the black will need to have contininity to ground. Also the orange/white at each coil should have battery voltage with key and engine stop switch on.

Change your coil

Does this motorcycle have a radiator if so, make sure it's full if it is go online and see if there's a sensor that shuts the bike down when it gets too hot. Maybe there's something wrong with that

compresion tsest could be a slightly bent valve, or valve too tight, inlet side.

bad fuel ? clean out carby and filter then if no spark at the plugs start at coil

Hi Oscar follow the loom carrying the three yellow wires from the generator on the left hand side of the motor. These will lead you to the reg. it is an aluminium box with cooling fins on it. Usually under the left hand side cover. Regards Jim...

easy mate, get an old screw driver a thin one heat the end up cherry red, bend over the las 5 mm cool it and put into seal and gently move round and pull out clean area tap new seal in with deep socket right way round, make sure you see how it came out
