Hello Everyone!

I'm about to start cleaning carbs (maybe replacing carbs), updating breaks, suspension and eventually updating seat with rear seat delete.

Long story long, I purchased my 91' GSXR 750 in the middle of 2008. It had 30k of miles at the time of purchase and I rode it everyday I could in Minnesota for the next 7 years. Bringing rhe mileage up to 44k on the odometer.

Unfortunately, the bike was stolen from my "secure" underground parking in Minneapolis in 2015. Thankfully it was found a couple of weeks later, a county or two away in an Applebees parking lot.

Since then, it's been sitting in a heated garage while waiting to have the ignition swapped for one that doesnt fit the screwdriver used to steal it in the first place. 😫

First step is cleaning the carbs... Does anyone here suggest to rip the tank off and drop the engine to get deep and dirty?

Any advice as to how to complete that big portion of this project?

Anything helps! I'm a beginner and I'm excited about getting in over my head instead of paying dealership mechanic fees.

Thanks,
Matt

I don't post on this site as much as I should but I can tell you that you will find an overwhelming amount of information on cleaning carbs. I, personally, spent the money and upgraded to Mikuni flatsides on my 1990 GSXR 1100 but it all depends upon your long term plan for the bike and your budget. If you want to freshen up the carbs, do some research on here for the carbs you have, get access to an ultrasonic cleaner, partially disassemble them and give them a good soaking. Put a kit in them to freshen the soft parts and ride away. I do recommend you remove the tank and replace the seal between your fuel petcock to tank. They do leak as the bike ages. Have fun and good luck!

welcome. good to hear you want to repair/rebuild your 91 750.

even though i like oil-cooled gsxr's, i own 5 of them, carbs are finicky and not fun to work with. i'm currently working on two different gsxr carbs at the moment...so i'm a bit annoyed with carbs.

chances are that the carbs and tank will have "gummed up" if gas was not drained. so, start by disassembling the carbs and check the fuel tank. i'd dispose of the old gas from the tank, and check for leaks. the carbs will need to be thoroughly cleaned; every circuit/passage will need to be clear for gas and air. otherwise, you will have issues.

my objective would be to get the bike running, then once you have the bike running, then i'd decide if i want to further clean and restore.

keep us posted and good luck.

You need to decide were this project is going first before you doing anything - like are you keeping the Original Exhaust or will you be changing to Pod Filters, because that will have an impact on what you do with your carbies as far cleaning or needing to upgrade to a different stage jetting kit.
Personally I prefer the Mikuni RS36-D3-K carbs for this bike - but you need to make other adjustments to fit them.

Brakes are not bad on these bikes - just do full service and clean on them (caliper and master cylinder seals) just make sure you get a proper tool to pull the pistons. Replace discs and pads and they will be like new.

Suspension - Forks on these are good just get them serviced properly / Rear Shock on these is OK but not as good as the newer stuff, but you will need to get it serviced by someone who knows what there doing. Just make sure they both have the right spring range in them for your body weight - and it helps if you have a suspension guy that can adjust your Sag Settings after all the suspension is done.

At the end of the day it comes down to how much money you have to spend.

Just got the bike to its home so that my work can begin.
I REALLY appreciate the help from everyone so far! The guidance and ideas have been very logical and useful 👍🏼
