Greetings Ladies & Gents,
first time contributor(help seeker) here, thanks for the warm reception. I know you can help me...
I'm totally stumped. I bought a GS750 79' over a year ago and began work. Pistons, rings, dipped carbs, lapped valves, shimmed, new points/condensers, new coils, etc.. I run pods and a 4-1 Mac. Recently it was struggling to rev over 5,000rpm and hesitated after releasing the clutch at low rpm.
I read somewhere here that it might be a condenser, so I bought additional condensers to see if I had a dodgy one. After changing those out I went about setting the static timing. I followed the procedure set out by Bikecliff. I turned the beaker plate until the light flickered out and when i tightened the screws on the breaker plate for the right side points (cylinders 2/3) the light would come back on. I tried again and again and it always happened no matter where the plate was located. I set it as best as I could and cranked it over. I got nothing but backfires and hissing out of the pods (sometimes smoke) like it is igniting in the carb throat/intake manifold. It never did start.. I'm assuming the timing is completely out, but what it could be? - I have no clue. When I did have the plate set where the light was no longer lit, each time I leaned on the 19mm wrench to turn the crank the bulb would light up again...
Also, whilst changing the condensers I also removed the breaker plates to access the right side crankshaft seal and replaced it. It was leaking slowly. I was very methodical in my approach to the work so I don't feel that I made any errors reassembling, there just aren't that many parts. :/
I've searched the forum endlessly to find any answers previously supplied but to no avail. I'm so impressed with the knowledge you all share and I appreciate any help coming my way.
thank you.
