will a 82 850 motor work in a 77 750 frame

[Coady]

OK did it.

The 850 cylinders sat about 10mm out of the cases. The two outside sleeves catch and by gently tapping the cylinders into the cases they marked where they were hitting.

I didn't have any grinding tools available but figured since it was aluminium I could probably chip/scrape away at it. Sacrificed a small wood chisel and had them sitting flush in about half an hour.

BEFORE:

Where they hit.

Look centre top third of photo. And matching section acroos from that.

[Coady]

And sitting flush!

Nice!

Is there an o-ring in that oval seat? If so, it doesn't look too good!

[blowerbike]

i have a wood chisel.

I tracked down a 83 750 and carbs for 150.00 ..would that work in the 77 frame ?

no it would not.
anything can be made to fit with fabrication but the only bolt in is what came in your bike.

[alstone89]

would a 81 750 16 valve head work with the 750 77 bottom end ?

Find a GS1000 engine, 1978 or 1979.
Easy swap.

[alstone89]

yes i like that idea but i have had no luck finding one...but i keep finding great deals on 750s ..and if one of them would work at least i could get the bike on the road in the mean time. thats why i keep asking these damn questions sorry if i am annoying you

Will a 1974 moped engine work in the 77 frame..??har har ..i picked up a 77 750 engine and a 82 850 for 75.00 each both running good . The 77 kick start will not engage the engine , is there a shear pin in side that could have snapped ?

77 GS750 Clutch cable connection, engine side HELP PLEASE?

Here is a picture of my problem



I couldnt bend the tab to get the old cable out so i unscrewed the bolt and nut that goes into clutch shaft....

now i put everything back together and fit the flat end to flat and, but when i pull the clutch i only get resistance from the spring...there is no clutch disengement feeling.

If you looking at the pic: i can grab thepart that has the threaded hole and the 2 flat sides, and i can turn it 360 degrees...

was i not suppose to take the nut and bolt out?

is my solution behind the cover with the 3 screws you can see in the pic that form a triangle?

please help, i may have to buy a manual if i cant figure it out soon, i just missed the bike night at quacker state and lube because of this ****...

STEP 1..At the clutch lever there is an adjustment screw with a jam ring..set that about half way in on the threads

STEP 2..down on top of the sprocket cover where the cable passes thru set that adjustment about half way as well

Step 3..swing the arm back up and put the washer back on, insert the screw back in till you feel it bottom out against the clutch push rod and then put on the nut but dont tighten the nut..leave it slightly loose

Step4..turn the screw in or out till you start to get the resistance back from the pressure plate against the pushrod when you squeeze the clutch lever. when the clutch lever is at the fully released..away from the grip..you should be able to move it a little bit just before you start to feel resistance while squeezing.

Step 5.. get on, squeeze in the clutch and start the bike..put in gear and slowly let out the clutch just enough to see where it starts to grab. you should have about 3/8 inch play between the clutch lever and the grip before the clutch starts to engage. Fine tuning adjustments can now be done at the clutch lever and on top of the sprocket cover. once you get it just as you want it..tighten down all the jamming nuts and replace the clutch accuator cover.

Post script..the thing with the three screws in the back is like a throw out bearing in a cars clutch,,basically the motorcycle version of it..spray some white litium grease down in there to lube up the ball bearings while you got it apart..and it is in the correct position just like it is now in the picture,..,just swing the arm back up and put it all back together as is.
