90 Katana 750 Issues

I just bought a 1990 Suzuki Katana 750 and the biggest problem with it is that the choke sticks on it. The piece that is supposed to slide back and forth to turn the choke on and off is pretty well siezed up. It can be moved slightly with a pair of pliers, but thats about it. I am planning on taking the bike apart to get to it and try to fix it. Is there anyone that knows these bikes and what might be wrong with the choke? Any tips on cleaning the carbs out? The bike has been sitting for a while so I need to clean everything out. The other thing the bike is going to need is fork seals. The actual forks are in good condition with no pitting on them. The rubber is cracking pretty bad on them and they need to be replaced. Is that a hard job to do? Do I need any special tools to do it?

It should be a slide action going accross the carbs. Have you tried to simply lube it?

The forks... its not hard. Get a service manual with a parts diagram. Check the sticky in this forum section. But you will want to replace the bushings, seals, and fork oil.

While you're at it you might as well go over everything else... brakes, tires, ect...

Thanks for the info, I havent torn into it yet, hopefully this weekend. I am hoping it may just need to be lubed, but I'm not sure. I am not familiar with these bikes at all and I was hoping to get some things to look for when I take it apart. I will look over everything, but right now, I am replacing only the parts that have to be replaced.

Another thing, are there any specific problems that I need to watch for with this model of bike?

This Forum:..............


is THE place to go for Katana info.....lots of riders, builders and modders.
(Sorry for pushing another forum, but NOBODY knows more about kats than these folks and they have a huge maint and mod database with lotsa folks willing and able to help) The only weak points of the kats were the soft springs and suspension; but there is a lot of aftermarket stuff out there. Otherwise, they were pretty much built like bricks, reliability wise.
