How can you wait that long, fire that baby up!! LOL Seriously though, good luck even though you won't need it :)

Mate I'm itching so bad I feel like I got a rash!

Thanks and I'm hoping it all just works... :pray:
 
COME ON ALREADY!!

Kick 'er in the guts, Max.

I've gone back through what I missed.
Hell of a job you've done, Pete.
 
Cheers Leigh, I am sitting here at work eatin' and checkin' on the forum coz I need my fix... it's the only thing I can do to get my mind off the first start... roll on Saturday!!!!!
 
With any luck I will be busy Saturday.Will check in when I can.Really hope this goes well!
 
So instead of twiddling my thumbs waiting for Saturday, I figured I'd adapt the GSX600F left control I got so I can start on the 'bar mounted choke lever. It'll be really hard to use the choke lever where it is once the exhaust gets done, so it needs to move for sure.

So, I need to swap these:



I already worked out what wires go where on both, although I took the GS ones from the wiring diagram:



During the work, I had to scribble out some of the above as I discovered that the GS has a ground wire (black/white) that the GSX doesn't and is superfluous. In addition, the horn wire is blue/white, not black/white as they show in the diagram.

Also, just to add some weird confusion to the mix, the yellow wire for the high beam is also attached to the horn switch. Very weird...

Anyways, lopped off the ends so I can attach the GSX wires to the GS plugs:




I know it seems nuts, but I'm reusing the OEM plugs as is because I have no others at the moment.

If I end up doing the custom harness, then I will definitely replace them, but the OEM ones will be just fine for now.

And there we go:



You can see the superfluous black/white there which I popped some heat shrink over to make sure it doesn't connect with anything it shouldn't, and I did the same for the two black/yellow wires that are used for the clutch switch on the GSX in OEM form. I'm not sure if I'll have a use for them or not yet, so I've left them there undisturbed at the moment.

Plugged into the harness:



And mounted on the 'bar:



The only concern I have is that even though I tightened the mounting screws up real tight, the whole control seems to rotate around the 'bar fairly easily from the pressure required to move the choke lever.

I'll have to work something out with that for sure. Possibly a thin bit of foam rubber or something to increase the mounting pressure will do the trick.

As far as Saturday goes, looks like the dish washer has decided it wants to be ultra conservative with water usage... it won't fill any more. Not sure what's going to happen, but I won't be surprised if I end up having to go dish washer hunting on Saturday...
 
How loose exactly is the control? Maybe a coupl wraps of electrical tape would do it?
 
Hmmm maybe... it's not loose as in flopping around.

I can push the horn button and it stays where it is, but pulling and pushing the choke lever make it spin on the 'bar.

It feels almost like it's built for 15/16" 'bars instead of 7/8"... I know that size doesn't exist but that's sort of what it's like.
 
Just tell the dish washer to stop her dramas and just get on with it and wash the dishes properly like she used to. ;)
 
No water in the dishwasher?
Dry cleaining your dishes. Very good.
You're an ideas man, Pete.
 
Do you plan on putting a black seat back on the bike or are you going with the red one? Personally I would say black I did not like the way that seat clashed with your tank. Just a question and opinion not an insult.
Respectfully,
Paul
 
Hahaha you're a bunch of funny buggers :p

I'm just trying to conserve water ok? :rolleyes:

I need to pull the thing out... found a place on line that lists parts for it so I might be ok, we'll see...

Did your old one have a tab that fit into the bars and this one maybe doesn't? I found that with mine.

Nah, nothing that simple I'm afraid. I've got different 'bars to stock too, but the old ones definitely don't have any tabs like that.

Definitely getting it recovered in black Paul! :)

The tank will be getting some paint too, and probably the front and rear mudguards also.

And don't worry, I don't insult easily... usually... well sometimes anyway :p
 
Well... first of all I missed this thread's birthday by four days... belated happy birthday thread! :rolleyes:

Anyway, I had a successful yet disappointing day today.

Successful, in that the spark issue is sorted enough to at least get the bike fired up and I think the timing is ok or close to it, but not 100% sure yet. That's where the disappointment comes in...

For the details of what went on, I started this thread:

http://www.thegsresources.com/_forum/showthread.php?t=173881

In a nutshell, it runs ridiculously rich and won't go above a stumbling idle and just the load of the timing light is enough to make it stall.

So... for solidarity's sake, I'll run through what I did...

Got the R/R mounted so I could test the stator and R/R, but never got that far unfortunately:



Lined up the tools:



Multimeter, John's scope, and the timing light (note my ultra safe work boots).

Rag clamped to the carb intakes to do some filtering and somewhat restrict the intake:



Temporary fuel tank hooked up:



Made sure this was standing by:



Fan at the ready as advised by RapidRay:



Very knackered OEM exhausts:

 
Exhausts mounted:



There is no muffler on the left exhaust, it rusted and fell off years ago, and I don't think there's much in the way of guts left in the right muffler either.

Possibly the dodgiest battery connection I've used:



My only jumper leads are missing the insulation on the handles of the red lead, and while sitting still without the motor running I can easily keep it isolated from the frame, but I figure with it running, it might vibrate and touch the frame and short out, so I extended the battery lead. Amazingly enough there is no voltage drop with this connection.

Car battery ready to roll:



At this point, I did some cranking with the spark plugs out to get the oil circulating.

I also managed to prove the oil was circulating through the head:



Bugger! Got oil over my shiny wet blasted cylinders... oh well, had to happen some time.

Bolt in on both sides, no idea how I managed to miss putting those in:



So, cranked some more and the oil light was well and truly out and I could see there was definitely oil moving around in there by the above.

So, starting time:



Apologies for the crap videos, but my camera has an auto stop timer that you can either set to 2 seconds or 10 seconds, you can't turn it off. Very annoying.

While it sounds sort of like I remember in the second video there, it's definitely not right. It ended up backfiring through the carbs a bit and wouldn't rev and if I pressed the button on the timing light it would stall after a second or two.

Longest I had it running was probably a couple of minutes at the most.

I thought I wasn't getting enough restriction from the rag, so I ended up folding one over in four and adding some duct tape to really restrict it:



If anything it ran worse with that, and then I pulled the plugs and noticed how black they were.

Left plug:

 
Right plug:



They are showing it's running far too rich. If anything I expected lean due to the lack of mufflers and using the rag for the intake instead of the airbox, but that's not what I got at all.

So now it's a matter of hoping someone can point me in the right direction because I'm out of my depth now unfortunately.

I also have no idea when i'm going to be able to try kicking it over again, the way things have been this year I'm lucky to get one Saturday a month on it. Might have to take a day or two off work soon so I can get this sorted, I'm so damn close!
 
Buck up man.You have at least 1/2 the battle won.It runs after 9 years.Sounds pretty good to.The rest is just getting bugs out.

Yup indeed! Definitely not complaining about the fact that it runs... coz that's just plain awesome :dancing:

Now to find the time to try again...
