This being my first post, I will introduce myself. My name is Terry and I have a '82 GS750T that I purchased from a friend I work with. Overall the bike looked great but my first mistake was overlooking the fact that he had to ride with the choke out a little in order for the bike to run properly. He was running pods and said that he and a friend tinkered with the bike a little to make it "better." Being a complete newbie to a carbohydrate , I overlooked that and was so excited to have a bike again!! Well I might have had a bike again but it sat in my garage for a year with me trying to fix all the stuff that they had done to it. Like I said before, he was running pods and they had also changed out the rear sprocket to take out one of the teeth. They also changed the main jets only from 112 to 136. Crazy right?
Well I searched through countless forums and websites till I found this one (which is the best thing ever
) and used all your info and amazing experience to help get her back running the way she should. I changed all the gaskets on the engine (except the head and lower, no clue how to do the mechanical stuff). Found the factory air box on ebay and a junk yard and put that on. Disassembled the carbs and gave them a good cleaning and soak. Re-adjusted the float heights because the P.O. had changed that during his "fix". Put brand new main/pilot/starter jets in. Put it back to the 112 for the mains. I shimmed the needle up a hair due to the fact that the ebay box had two holes in the filter housing versus the one I saw in factory pictures. I did this to maybe keep it a little richer in the higher throttle parts. Also checked the diaphragm on the slides and there were no holes in them and had good suctions once placed in. Did a bench sync for the carbs. Checked the air boots on the box and engine and they were free of cracks. Put a little bit of Mystery Oil on it and carbs popped right in! Changed out the vacuum and fuel lines to make sure good flow and had no cracks. Changed the spark plugs. Changed the battery. Had someone put new tires and fork seals in to make sure it was safe to ride. And I did an oil change. Once all that was done, I did a true sync to the carbs with the adjustments shown through the welcome packet! Also adjusted the air screws as well. Started 2 turns out and went from there.
All this was said just to let you how helpful this forum has been and what has been done to the bike. The problem I am having is that once she is warmed up and running, anything past 1/4 throttle the RPM's jump about 1,500 or so and the bike loses power while riding. I can let off the throttle and it immediately drops down to normal and power comes back, but any pull past 1/4 throttle she will do this. It is a real bother when trying to pass someone or if in any emergency I don't have any go to get out of the way! She starts up perfect. A little choke and two clicks and she is up and running. I checked the plugs and they all have good blue spark and do not look gritty or burnt. I have even run with the choke out a little to see if it would enrich the mixture and maybe stop it if it was starving for fuel in the high gears and RPM's but to no avail. I can not figure it out. If any of you guys might know a solution or have come across this I would greatly appreciate it. I would love to be able to ride without the fear of losing total power! I appreciate your help!!
