Question about 1989 Suzuki GSX 1100 FJ (Katana)

1 Answer

1100 problem So I bought this 1100 and have been getting it ready, new tires, new exhaust, oil change, and so on... I have taken it on 2 rides and the problem has happened both times. The bike is in the shop now but I wanted to ask the experts here so I can throw the suggestions by them. The bike starts and warms up properly and runs pretty good for the first 30 to 45 min. After that the bike looses power and starts sputtering. The first time it happened I was out for about an hour and right before I got home it started. I was taking the bike in today to get the rear brakes bled and had to stop at lowe's on the way and the same thing happened right before I got to the shop, the bike started sputtering, loss of power. Is it a carb thing or an electrical thing? Any advice would be greatly appreciated. The bike has 24K miles and the previous owner said that he just had maintanence done on the carbs. As far as he knows there is not a jet kit on the bike but it does have the K&N filters and I am running a V&H SS2R. I told the repair shop that if it needed jetted to go ahead and do it. I probably should call them and let them know which jet kit is recommended by V&H. Thanks Ya'll....

I had a problem like yours and it was dirty into de carbs and in the fuel key. A good test to know if all the cilinders work is to put a wet paper or a tisue on the exhaust head of each cilinder and then you can see if they work...this is to know if the lost of power is becouse the engine doesn´t work complete...You can make this test in different revs...

Backfires badly when downshifting or just letting off the throttle v-star 1100

Most people have this problem after changing the exhaust system. In your case you have to unbolt the exhaust system just to change the oil filter during an oil change. There is an oil filter relocation kit available for around $400 that allows you to both use a spin on filter and not have to unbolt the exhaust system every time you change the oil. The cause of your problem is air leaking past the exhaust o-rings in the head. Buy new exhaust o-ring gaskets for the head and your problem should be solved. If there is a sealing pipe gasket going from the head pipe to the muffler you may have to replace that too. The cause of your problem was probably an oil change where the mechanic replaced the oil filter but did not bother to replace the exhaust o-ring gaskets. Happy riding.

I doubt the bike has 100k on it, thats alot of riding! If it runs and looks good just figure it is a typo and ride it. As far as the oil filter that bike uses a spin on filter, it is painted black, screws on the front of the engine just above the oil pan just to the right of center.

The silcolene does not burn as well as standard two stroke oil. The unburned oil has to go somewhere and out the exhaust is it. Get a new gasket anyway. It should help.

Oil filter

Hi .... Have a look at the front of the righthand engine casing, it's there. You have to take off the exhaust to get to it, allegedly a 1 1/2 job inc taking off the exhaust. There is an aftermarket kit for relocating the air filter, takes only 20 mins all in then from start to finish.
