GSX 1100G stored for a year - starting order - do you agree?

[gandy666]

Hi guys

I've bought this shaft drive bike thats been stored for a year or so with a 3 quarter full tank so there's some rust in the tank, tho its sound. only surface. has apparently been started recently, so the assumption is some rust flakes are in the carb.

I've had a look around the forum and there is a lot of information, which great. Following on from this, the following are the steps I intend to follow to get it started.

Is there anything obviously missing or can you help with anything that will make it easier - thinking its a pretty big bike so dont want to do any unneccesary damage.? thanks in anticipation.

1. remove the petrol tank and drain the old fuel. keeping it aside for rinsing the tank out. heavy bits will sink to the bottom and will be rinsed later. take of the fuel cock cos its alloy and may be affected by acid, plus it'll need cleaning.

2. nuts and bolts in the tank with some petrol to dislodge the lose rust. drain and rinse with old petrol..

3. oxalic acid in the tank for 8 hours to get all rust off, agitating and checking regularly so it doesn't take off to much metal or wreck the tank.

4. check and clean the fuel cock. check the air filter - replace if manky.

5. drain the carbs - blow down the fuel pipe to force out any crap. can any damage be caused by blowing too hard?

6. skoosh carb cleaner down the pipe in to the carbs, drain.

7. close the carb drain screw and skoosh in some carb cleaner in case their gummed up so it can soak. maybe skoosh some up the drain screw - thinking pressure will force it through the jets and idle holes.

8. spark plugs out and skoosh in some wd40 - would engine oil be a better choice here?

9. put the bike in a high gear, turn the rear wheel slowly to get the engine internals moving.

10. drain the petrol tank, rinse well with water.. leave it dry somewhere warm overnight. finish with a good skoosh of wd40 in the morning.

11. new spark plugs. new battery. attaching a jump starter pack as well to the battery for extra oomph. teaspoon of petrol to aid starting.

12. reattach the tank, stick in some high octane petrol. turn on and leave for a min to get some fuel to the carbs.

13. fingers crossed, start.

14. leave the engine running for about 20 mins or until it settles down. try the throttle intermittently, sucking fuel through.

15. once running steady, put into gear, take it for spin, building up throttle, gears and engine speed. not going to blast it - maybe an hours drive around.

16. park up, change the oil, change the filter.

how does this sound so far - anything missing?

pick of the bike attached btw - if i can get it running i will be delighted

cheers

I would put non ferrous bits in the tank , but I doubt you will dislodge all the rust. Not sure what good the oxalic acid will do?

I have a 18 month since last run Blade engine. I took plugs out, sprayed 3in1 in , left 24hrs, turned engine over with nut on end of crank about 4 times. Spayed more 3in1 or WD40 in, left 24 hrs, turned over by hand again and resprayed. Left 24 hrs then spun engine with starter motor, plugs out, more 3in1, 24hrs, more spinning. Plugs back in and I fired it up.

If that engine is an air cooled TSCC engine, I have stripped and rebuilt them a few times!

they are basically a shaft drive gsxr 1127 motor mega but it dont matter what it is at the end of the day if he follows what you have said he should be ok

[megawatt]

Cheers mate, thought it was a GSX air cooled motor , not a GSXR oil cooled. Dunno about the internals on GSXRs

[gandy666]

it is a GSX air cooled motor.

[megawatt]

Thought so! EAB yer sacked

Nope, just found this;

[eastanglianbiker]

can i have me job back now please mister

[gandy666]

until i get it running its a lump of expensive metal.

looks to be in good nick so he's hoping

[gandy666]

so the update is I got the bike running at the weekend.

I partially removed the carbs, removed the bottoms, checked the float bowls on the 2 outers and there was no old fuel residue plus the floats were absolutely fine and there was no crap inside the bowls so assumption is jets are clear.

assumption was that as the outers were clean, so would be the inners. didn't take the tops off the carbs. skooshed a load of carb cleaner through the carbs via the airbox.

anyhoo, bike runs sweet when i use the throttle. runs on the choke on start up. took it for a spin on the throttle, did a mile or so to get everything moving, again constantly on the throttle. keepin it up around 2000 revs.

as soon as I try to get it to idle, dies immediatley. off the throttle, dies immediatley again.

Have tried turning the idle screw both left and right however this has no effect. will have a check to see if it is actually engaging anything.

assumption is the carbs are fine since I can rev the engine without issue. bur refuses to idle, even for a second.

any ideas?

[Fozzie]

Idle circuit/jet is buggered and blocked from the sounds of it

While it looked clean the bigger jets may be getting fuel flow but the idle jet is small and easily gummed up.

Take em off and give them a proper clean, then check float height, set the carbs back to their original setup and then balance them. I reckon this would sort it!

[gandy666]

how do I remove the throttle and choke cables from the carbs?

slacken them off at the throttle handle / choke lever then slip them out of the spring loaded holder?

got kinda stuck and couldn't see they came off.

cant find a manual for a 1991 GSX1100G anywhere.

is the engine the same as a non g gsx1100?

cheers

[megawatt]

A GSX1100 is an air cooled motor mate. Yours is oil cooled. More likely a GSXR1100 manual would do?

smashing - thanks for the link to the manual.

Yeah...I think Fozzie is spot on....sounds like blocked or dirty Idle jets. You may be able to remove and clean them without pulling the carbs off completely. Unscrew the idle jets completely and check the tip to make sure they are clean....then you may be able to give a squirt of air through the port to clear any cr*p in there. Put the idle jets back in and set up to manual. This may work if you get lucky....otherwise the best thing would be to remove the carbs and strip and clean them.....
