Hey, I'm new here. I recently picked up my first gixxer and its also my first Suzuki.

It's a Canadian model '92 so it is water cooled. I literally found it around the corner from my house. Tucked away in a barn I have gone by a thousand times. It was so close I pushed it through a cornfield home, instead of going to get the trailer.

Image


This thing is super original and in really good shape. Its extremely rare around here to find a old sport bike that has escaped being turned into a squid-missile at some point.

An old Hindle can and a blue windscreen are the only modifications.

Image


Just over 14,000km
Image


The only significant damage I have found so far:
Image


I had it running today, but it was struggling a bit. I have a receipt showing it got new plugs and a carb rebuild in 2019, but its been sitting pretty much since then. Going to pop the carbs off in the next day or two and take a better look at them.

Anyway I just thought I'd share some pics. I'll probably update this thread as I continue to to through the bike.

Nice find, indead clean the carbs and she will be running again, best strip them and throw them in a ultrasonic bath, dont own one....go with your stripped carbs to a shop that has one, so just the upper bodys empty and jets, wont cost much. replace o rings, or just get a carb rebuild kit (she's worth it) and have fun., for the rip in the back, take a paperclip, cut in a few pieces and use this to reinforce the broken part, take a solder iron and just melt them in from the backside, then get some acetone and some lego...or something else from ABS and throw a few pieces in the acetone, not to much not to litlle, leave overnight (closed botlle) and the next day you can use a paintbrush after sanding on the inside to make a layer on top of the rip, the nicer you work(line up) the less you will see from the outside. use multiple layers and brushes cant be re-used. you can search youtube on how to fix broken plastic, lots of great vids.

I did a quick clean today of the float bowls and the slides. They had a bit of debris in them, and two of the pilot jets were clogged, but they do look like they were serviced in the not too distant past. I do have an ultra sonic cleaner, but I'm trying to avoid a full tear-down just yet. I noticed one of the rubber tees for the vents to the air box is starting to fall apart, so I'll have to order a couple of those. When I separate them to install that tee, I'll probably through them in the ultrasonic. Thanks for the info in the plastic repair. I have a plastic welder I picked up for another project but never used, so maybe I'll give that a shot.

Here is another question, for you or anyone else. How do you get the airbox out? I have the carbs out but I can't figure out how to get it out without dismantling half the bike.

a yes, the beloved air filter box on the gixxer...thats the fun on working on bikes and making folks go to a shop. i remember its a tricky bugger and needs stripping the tail section, then you need to take evrything of thats blocking it and release the holding screws....and it should (if i remember correct) go out through the front with the carbs out. side fairing of would make it a bit easyer, cause you need to wiglle it free in a certain way, but i'll bet that someone here knows the excact trick, but its mostly a shit job with the box build into the rear frame.....if its just for your filter then just leave the box in, should be possible to change the filter without getting the box out. But be prepared to look up some curse words and lay down some cartboard boxes you can kick when your getting frustrated....or maybe keep a friend or family member near that you dislike.

Some updates on this bike. The previous owner purchased it in 2019. He paid a shop to clean and rebuild the carbs, plus address some other things it needed to be road-worthy. He never actually plated it and it just sat for the next 4 years. Going through the carbs I found a bunch of major issues. There is no way this bike ever ran like anything other than pure dog-shit while it was in his possession.
Image

After removing and installing the carbs 6 or 7 times over the last couple weeks they are finally sorted out. The rear brake caliper was seized, so I rebuilt it and added new pads. The front brakes looked great, so they just got a clean-up and a fluid flush.
Image


I fixed the broken rear fender with my first ever attempt at plastic welding. It's not perfect, but from a couple feet away you can't even notice. The inside was reinforced with stainless mesh, so It should be plenty strong.
Image


Image


I went over the rest of the bike to make sure it was rideable, and today the weather in Canada cooperated so I managed to get it out for a quick 20km test ride. It pulled hard and shifted through all the gears so I'm happy. It did have a slight bog at low rpm that I need to look into.

Image

The main issue it still has is the right mirror is flopping around. It looks like it's suppose to have some sort of foam inside it, but its completely disintegrated. Anybody have any experience with how to fix this?

I can't help you with your mirror question, but I just wanted to say, wow, what a great find. The bike looks fabulous. I have a 96 750, not as clean as yours but it works. Where are you located in Canada? I'm on Vancouver Island. Cheers.

Thanks, I got super lucky for sure. I love the carb'd SRADs too. My brother actually lives in Victoria. I'm in Ontario though.

Very nice bike!

I have been looking at replecement mirrors (EMGO) myself and they seem sursprisingly cheap. Around 20-25€ per piece. Maybe something to look at?

I actually picked on up last weekend. Its not bad. Its slightly different shape and has a big EMGO logo on the back. My bike is so original that having an obviously aftermarket mirror is going to bother me, but it will work for now.

The last shot of the bike before it was put away for the winter:
Image


I've been picking away at winter maintenance as of late.

Tear-down:
Image


The front brakes were dragging a fair bit still, so they were taken apart, ultra-sonic cleaned and rebuilt:
Image


Both master cylinders and rear brake received the same treatment:
Image


I replaced the possibly 30 year old brake lines with stainless braided lines from HEL. I got them in black to keep it looking as original as possible:
Image


The right fork seal had developed a leak, so the front suspension was also taken apart, cleaned and reassembled with new seals, bushings and oil. Did some wheel/disc cleaning also and got the front end back together:
Image


The muffler tip was rattling when the bike was running, so it was disassembled and repacked. I also gave it a bit of a polish:
Image


Swapped out the rusty steering stem nut for a shiny new one:
Image


Image


I also tracked down an OEM windscreen to replace the blue one. DId a good cleanup of the front fairing as I was in front fairing cleaning mode:

In my quest for originality, I managed to track down a rear rail that still had its reflector mounts intact (not easy to find!) After a bit of straightening, rust removal and a re-spray it was looking pretty good.
Image


I found some reflectors form a '91 which i believe are the same as would have been on my '92.
Image


After a thorough cleaning of all the bodywork she's all back together ready for the spring. Hopefully get her out for the first ride of the year tomorrow.
