Should i walk? Engine noise

[Guest]

Greetings. I'm looking at a 1986 or 87 gsx750esd. When idling it has a terrible rattle. I thought timing chain, but the seller says clutch is rattling when its cold. Says its normal on these engines? The noise disappears when revved above 1200. And supposedly when warm.
Compared to my 79 gs750 (totalled last week) - the older ones clutch didnt say anything.

On a positiv. The engine started instantly. No comparison to the old 750. And the engine sound had a growl and a fast reacting rev that actually scared me a bit. It sounds so much more powerful than the old

The noise stops when clutch is pulled

Then it's probably the common clutch rattle, and probably fairly cheap and easy to fix.

The Limited Edition 86 gsxr had a dry clutch, this is a normal sound similar to the clicking you hear on Ducati's. If it is the dry clutch version you are looking at highly valuable Limited Edition 86. BUY IT!

Thank you for the info on the rattle.

The bike is not the rare one, but the standard 750esd. Black with red decals. I have just 1 concern now. The counter says 22.000 miles. The bike looks very used. Scratches and small dents - it just doesn't look like someone loved it. This is why I hardly can believe it ran 22.000 or average 880miles in its 25 years. - and why I hesitate buying it.
If the counter rolled over once it amounts to 84.000 miles. (I converted the numbers from km). Is it too much in your opinion? And is there a trick to establish if it ran 22k or 84k. I'm thinking noticeable wear on something. - ok this is maybe a far fetched idea.

Look for wear on footpeg rubber, paint gone where your heels rub the frame, levers polished from fingers and toes, sand and rock pits on the front of anything hard down low, the seat sagged badly in the assal area, anyplace electrical wires sit will show signs of rubbing. The 84K bike will have a lot more of this stuff showing than the 22K bike.

Hi, I just wanted to finish the thread and let you all know I bought the bike. Here are some pictures. First impression is a bike that turns much more responsive than the old bike ('79 gs750). Engine a bit stronger. It's lacks a lot of maintenance that I'm going to take care of right away. Breaks are very poor - that will be my first concern. Some tabs on the side panels are broken. I'll try weld them with a acetone dissolved Lego brick. A tip I found around here.

The pictures look better than reality. It has some dents, alot of scratches. Worn down tires. Seat ripped. etc etc. I'll be busy and happy

Rattle

The classic old-fashioned way to determine the specific area of the rattle is to take a long 1/4 drive socket extension, or a long screwdriver, and, as it's running, put one end of the extension or the screwdriver on the suspect area of the noise, and the other (a little bit) in your ear, and use an ear plug in the other ear to cancel out other noise. Move the engine end of your listening device around to where the noise is loudest, or more specifically, like the unaided sound you hear from a little distance.

Break the basket apart, shim the springs with washers & have it welded up..



This from a British magazine on a smaller bike than yours but may also be a valid method of closing the basket back up....

I had a new basket that i put in it, rattle from day one. These motors are very durable. Mine has over 75 thousand miles and over 400 dragstrip passes on it.

What size OD washers and are they the same for all Gs's?

[salty_monk]

The same OD as the springs... I can't remember offhand. Nessism provided mine & they were simply commercially available washers, nothing special.
