Yet another question

[mjremington]

Ok, the valve cover gasket has finally arrived for my 82 GS750T. So saturday we are gonna do the clearance check. And also check the clutch and tranny system for the extreme amount of vibration at highway speeds. The vibration almost makes my feet numb but as soon as clutch is engaged the vibration stops. So, my question is this. Once we remove the clutch cover I'm gonna look for movement of the whole assembly (maybe the bolt is loose), or anything broken. But is there anything else to look for ? Also, is there a gasket I need to replace once the cover is off? Or, can I just put the cover back on? Thanks for the advice and I believe I'm one saturday of work away from having a top notch machine!!

The clutch cover being on the right hand side of the bike will have a gasket. The sprocket cover does not.

Have you checked your frame bolts for tightness? I have the same issue as you and it's diminished since I did that. Are your carbs properly synched? You'll need to resynch them after doing the valve adjustment. Do you already know what shims you'll need and have them available?

Ok, I'll order the gasket for the clutch cover. Yes, I should of specified, the one on the right side. Havent checked the bolts, but will now. Is there a spot I should start from? Yes, the carbs have been synced and we kept the borrowed tool until the clearance is done As for shims, I read both 8 and 16 valve jobs on BC's site. Only the 8 references shims, not the 16 as mine is. So I didnt order shims but the local shop said they have all the shims in stock. I know for a fact the valves were never checked by speaking to the only prior owner. But did my bike come from the factory with shims?? Or is that used when people have them adjusted? I'm a tad confused since BC's site didn't mention shims for my bike. Any thoughts would be wonderful. I'd like to have everything ready without having to make a special trip! God knows how much we hate those "special trips". Thanks Cowboy, because I'll check the bolts before ripping into the clutch but will have the gasket sitting at the dealer in case.

No you never had shims. I didn't check the parts fiche before responding, sorry about that.

Just make sure you adjust them as needed.

As far as the frame bolts, I was told to loosen all then tighten each one to hand tight then torque them to the proper specs.

Shims?

The 750t is 16 valves tscc. Their are no shims for that model. Requires adjusting the tappets, rocker arms which ever you prefer. 8 valve and 4 valve dohc require shims. Bob

Make sure all your engine mounting bolts are present and tightened, also check your chain and sprockets for tightness and proper operation. When your clutch is engaged, it releases the stress and load on these components. I may be something in your clutch, but, I doubt it, these clutches are pretty tough.

Make yourself a couple of these....square drive wood screw superglued into a dowel, it makes adjusting the tappets pretty easy.

Before pulling loads of things apart have you tried the basic's?

Carbs synchronised?
Engine mounting bolts there, tightened?
Footpeg mounts tight?

Not a problem Cowboy! I was just making sure measure twice, cut once! Besides. You got me thinking and asking questions before I tore into it. Which is good.

Thanks LarryD, I'll make the dowel tool tonight. The chain and sprockets are all new. But I'll check the chain tolerance again.

Suzuki Mad, yes the carbs were synced. Cleaned twice for good measure so they are good to go. I'll check all the bolts when we do the rest of the work on sat. But I'll refrain from touching the clutch and tranny system until all other possibilities have been checked/fixed.

Again, thank you for the replies, help, and knowledge. It's really helped. Kept me from giving up. And I'm just a little work away from a damn fine machine.

Just a suggestion but if clutch springs haven't been replaced, I would do that if you take cover off. Also pull clutch plates and measure for proper thickness and clean the metal one up. Don't know if it will help vibrations but will certainly help you clutch. terrylee

Here's an oddball sugestion.

Have you checked your exhaust mounts?

Are you running any kind of open exhaust or punched-open exhaust?

Because this can cause A LOT of vibration.
