Anybody in Ohio want to lend a hand?

[Guest]

Hey everybody I just swapped a new to me engine into my bike the whole points setup was removed so I installed the setup off my old engine and I can't get it to fire. I tried testing to points with a test light and I only have voltage to one set and spark on 2 cylinders but it looks erratic and weak. Any help would be appreciated. Oh by the way it's a 77 gs750 but I believe the engine is newer the engine is stamped gs750-72085

Ohio is a big state. You may want to provide a little more information, such as where in Ohio you are.

Did you replace the points, condensers, and spark plugs? Check point gap?

The points get power from the coils. You might want to check to see if both coils have hot power. If not, you have to start tracing wires. Get out your factory Suzuki service manual and pull up the wiring diagram. Easy work, just a bit tedious.

I'm in medina county I will trace some wires later I know only one set of coils have spark

Ok I was able to get it running but only on 2 cylinders I checked all connections for the coils with a test light and they had power I also tried 3 different coils with no luck so where do I go from here? I don't have a manual and can't download one with my phone so any suggestions would be great

Ok so I was able to get power to both sets of points and I switched the coils around and they both work on cylinders 2 and 3 but still no spark on 1 and 4

Old set points also.... actual breaker points yet....?
Two condensors...?
Try swapping the condensors, ....or just disconnecting the one on the set that doesn't spark, if it sparks more (across spark plug gap) with condenser disconnected then know the condenser is bad (and might spark more across points also).

Also, do an ohm check from one cap to the other cap on that coil. Should be about 20K. If much higher than that, take off each cap, cap off of the wire, and do an ohm check on the cap, should be about 5K ohm each.
CAps do go bad with age and useage, go to a higher ohms as they go bad then go completely open (infinite ohms). COst about $5 each.

Medina... south east of Cleveland, right?
(I lived in Euclid for a couple years.)
Cant think of any GSR member near there.
Some more toward Erie PA, and a few in Dayton area (but that is not close).

I got her firing on all 4 now but the timing isn't right and the carbs need a good syncing and fine tune. I also discovered the oil drain hole is stripped anybody know a fix for this that don't require me tearing the bike completely apart again?

Welcome to the forum. The search function is your friend. There is a huge wealth of knowledge here.

Good luck getting your bike sorted out!

Oil pan fixing. Drain the oil and lay the bike over on its right siade after removing the side cover and tank. I layed my 1000 down on a old truck tire for cushion. replace the oil pan and gasket.'

Some have used whats called a Plus 1 drain plug. I have one actually and found it hard to get started to recut the threads so I just replaced the pan itself.
