Newbie with a GS1000s

yeah..i forgot he said it came from Europe at one time. I got a set of those 28s on the shelf.
 
Hi to all,
It has been some time since I last posted, this is down to frustration.
I have done the valve clearances, stripped and rebuilt the carbs. Put it all back together, started her up and it still sounds like a box of bolts.
I put it in the corner of the garage and covered her it over for a while.
My wife threatened to buy me a box of matches for Christmas so I could set fire to it, so this has led me to see if I can do something.
Yesterday I bought another engine, but it is from a GS1000E number 146414.
I was told when I first posted that the engine currently in my bike is probably not the original one, not that that really bothers me.
I do now have questions.
Are the engines basicly the same.
The carbs on my bike are different to the ones with the engine I have bought. I have VM's at the moment and the engine came with CV's, can I use my original ones with the replacement engine.
The engine has come with Boyer electronics and the fitting instructions, my one had the original points. Can I assume this would be good to keep.
Any help would be good.
Regards Clive
 
Clive,
Unlikely you'll be able to use the VMs on your replacement motor, as the newer cylinder head's intake ports are larger. If you want to keep the mechanical carbs, you can swap heads (the motors are basically the same); otherwise, go with the CVs, as they're decent carbs for a streetable setup.

Electronic ignition is definitely a step up.

Good luck with the motor swap, and put away those matches.

Thanks for a quick response Frank,
All good information.
I have to clear a bike off of my work bench before I can start the swop.
Hopefully over Christmas or early next year.
Regards Clive
 
Reading earlier posts about your rattling noise, have you checked to see if the cam chain tensioner is functioning/adjusted properly? Could be you're getting cam chain slap. Just a thought.
 
Hi Frank, all the noise seems to be in the starter clutch area.
I looked into replacing it all, but the cost was very high.
The replacement engine appears to be fine,so I will try this first.
At the moment, I just want to be able to ride it. I think it is a cracking looking bike.
I can in time strip and try to sort the original lump.
Regards Clive
 
Clive, good luck on the new engine.

Removing the engine on the GS is actually quite easy, there are a few tutorials and videos on youtube.

My preferred way was to remove the top of the engine including the head.

I would place a milk crate (or wooden box) at the same height as the engine to the right of the bike.

I would then straddle the bike and lift the engine out sideways, with the head removed it was much lighter and gave clearance to lift it out.

With a bit of practise I could get an engine out and on the bench in well under 2 hours.

Now putting that new engine back in will need 2 people if you don't want to tear it down, but you may want to remove the cam cover as it gives you that extra little bit of clearance needed. (as you may want to check the valve clearances anyway)


Cheers,

David.
 
Thanks for all the replies.
There will be two of us when the engine is swopped over.

It seems like a lot of trouble to get the best results.

Why not take Chuck's advice on the repairs to the starter clutch? After all, you don't know what you have that is the cause of the noises.

Just my two cents.
 
I have to agree with the consensus... It sounds like the engine you have in it runs well, and just needs some repair. Putting an unknown engine in it may open up even more problems. Besides the fact of keeping the bike as original as can be. Just sounds like more work, money, and wife griping if you run into problems with the replacement... Good luck either way...

DITTO. You're basically taking what is essentially a two-hour solution and making it an all-day job.

I would go for the starter clutch first. You'll know as soon as you destruct it whether or not that is the source of your noise.

Also, going from a VM motor to a CV motor, you'll have some difficulty getting the tank to fit as the petcock will likely not clear the tops of the CV carbs. And to complicate things even further the petcocks are not interchangeable.

Hi to all,
After listening to everyone, I got the bike back on the work bench. I decided not to change the motor and use the replacement one as spares.
I stripped the starter clutch off and it was all pretty well had it.
I stripped the starter clutch off of the replacement engine and it all looked fine, so I have fitted it.
Upon starting the bike up the noise has gone, but only to be replaced with another noise this time coming from the clutch.
I then stripped the clutch down and found the springs in the back of the basket to be very loose. Back over to the replacement engine, I removed the clutch to find that the basket had been modified with stronger springs. So I have fitted that. Started the bike and it sounds lovely.
The bike has cheap pod filters fitted and when I open the throttle it is not happy until the revs get up a bit, so at the moment I have put some duck tape round part of the pods to restrict the air flow a bit. This is a vast improvement, so I am now thinking of going back to an original air box.
I have taken it round the block and the motor is very quiet and the bike pulls very well, although my wife says that the stubby Harris pipe is very loud.
I am nearly there now. I have fitted a pair of mirrors and I have changed the speedo for an MPH one, as the bike came with a KPH one. Next week I am hoping to get an MOT on the bike and start to use it.
So I now have a few of questions.
Does anyone have a complete air box to suit my bike for sale and is there anything I can do to make the exhaust quieter and can anyone explain why my bike has a steering lock in the side of the headstock but all the suzuki website do not show one there. the reason for asking is that there is no key, so I need to get something.
Regards Clive

First I've seen this thread, nice bike, I've never heard of a steering lock on the side of the headstock, have you found an airbox? They turn up on ebay occasionally.
 
Hi tatu,
I have not got an airbox yet, I have been looking on a Suzuki parts supplier here in the UK today and the part numbers are the same for the S, EC and EN models so that would make it easier. There is one on ebay at the moment but it does not have the cover where the filter goes in. Suzuki do not seem to supply them seperately.
I am not surprised you have not heard of a steering lock in the headstock, but it's there.
Thanks for the comment about the bike, I like it, I cannot afford a standard one as they go for quite a bit over here. But it is sometimes nice to be different.
Regards Clive
 
Maybe just get the bits as they become available on ebay, one thing to look out for is that the carb rubbers need to be good condition though I read here that gs750 ones fit ok. Mine had a mutilated top cover for a long time.
 
Hi tatu, I have been thinking along those lines tonight.
I am sure I could make a cover until an original one turns up.
Regards Clive
