Question about 1995 Suzuki GSX 1100 FS (Katana)

1 Answer

GSX 1100 ignition

My tach drops to 0 then bounces back up when I'm on the highway. I thought it may be a carb issue. But when this happens I can downshift and open the throttle up and I have no problem, that is until I let off the throttle. It really bucks when this happens. It's not fun doing 90 and your bike shuts down for a split second and then resumes the speed and then shuts down again. Talk about getting jerked around. Talked to a Suzuki service manager who said it sounds like ignition. But of corse he wouldn't go any further into what to check. So any help would be much appreciated. Thanks

Igniter boxes don't actually fail all that often. They are fairly robust. The coils can be problematic, but tend not to do the sudden on/off thingie. What can result in this is a leak between the #3 carb intake runner and the gas petcock. The number three carb supplies the vacuum which 'runs' the stock petcock. Does it still do this on the Prime setting? If not, then for sure its the vacuum line etc.. Good luck!

Gd evening. my motorcle stall @ 60 miles per hour then doesnt drop below 50 miles per hour wen riding on interstate. change fuel filter,gas. blew it out on highway it picked up normal speed for about

Well, it seems you were looking at the wrong gauge...

Speed doesn't matter, but rpms MIGHT matter. Next time this happens pay attention to the bikes behavior relative to the tach. The next thing I would do is make sure the plugs are fresh. It's a cheap shot at the fish in the barrel, but if that doesn't take care of it chances are you have a carb problem and that will need to be taken apart, cleaned, checked, and set up properly. I only recommend changing the plugs first as a proper carb job can be daunting for a novice.

Suzuki GSX 1100 EF carburator overflowing

If the carbs are overflowing it's often because a needle valve or valves are contaminated with dirt or gum and being "held" open. Suggest strip carbs and clean.

My 1998 Yamaha R1 rev counter is jumping up to 7.500rpm then dropping down to 0, then going back to normal, also it sounds a bit louder than usual. It sounds as if an exhaust gasket may have gone. Any...

Typically Yamaha used the firing cycles off one coil for input to the tach. The noise you hear may be misfiring on one or more cylinders. When tach drops to zero cylinder coil isn't firng, when it jumps up its firing again.
The erratic tach usually means an igniter (ignition black box) problem.
Get a manual and start with testing the pickup coils, they signal the igniter when to fire the ignition coils.
Then test the ignition coils for primary and secondary resistance, check igniter connectors for clean tight connections, full battery voltage supply to igniter etc..
Occasionally getting the igniter wet can cause erratic behavior till it dries out.

I have a 2003 yamaha yzf 600 the tach dosent read correct

I do not believe so, as the tach is related to your firing electrical pulse. have you checked the tach wiring for loose connections?

I need a detailed diagram of the carbs for my 1981 GSX 1100. The one in the Haynes manual I have is not very detailed.

Google babbitts sports then click on buy oem parts and then select your specific bike. A parts diagram will come up, change the page from 'air cleaner' to 'carburetor' on the drop down menu and you can see your carb assembly. Hope this helps...
