I am thinking that once guage set they will probably get even better performing.

Jap Bike Randy..the guy at Killeen Powersports will do them for me. Hes a buddy of Winslow ( horsepowerfarm ) here on the forum. Winslow is also the man with the new bike shop starting up in Austin. Anyways Randy said he would do all my bikes for me. Now the others need the valves checked and gone over and the full monty, so to speak. I have learned a lot in 3 years and someday i hope it pays off to fullfill my dream of working in a bike shop. I still got a LONG LONG way to go but i am determined.

Hi,
Keep them, somebody might need them one day.
Congratulations on your success! It's good to hear that your bike is running so much better.
Thank you for your indulgence,
BassCliff
need to get this info to highway glider.too..

good to hear chuck that it's doing what it should now ride it and do a few more plug chops to fine tune it and then enjoy it for what it is
a fantastic 34 year old bike that runs like it was new

Im think its still a bit lean but man what a total transformation.. I was looking at the chart that has the bikes broke down by engine numbers. According to that chart my engine number says the air screw should be only 1 turn out. But for now i am happy it is acting like it has all 750ccs again.
Congratulations and I'm glad to hear you finally sorted it out. :clap:
Hope you have many fun miles with it.

I cant believe you went through all this and have yet to DIP those carbs.
Chuck, if you're gonna do it at least do it right.
Good to know its running better, for now..

Octain, Wiredgeorge had all ready cleaned them and Chuck made sure all the passages were still clear. I see nothing wrong with the way He did it.

If it works it works.. But if you're gonna go through all the steps ya might as well do it RIGHT.
But thats just me..
Glad it's working better Chuck. Now you know why I keep my bikes stock.
As far as some chart suggesting 1 turn, I'd disregard that. Suzuki didn't publish that kind of info for the most part, and if they did it may have been related to emissions.
Next step in your school'n should learn to do plug chops to read each carb circuit. I'm not that familiar with it myself but I know how important it can be. I've read about some drag racer guys running their bikes with a couple of plug wires pulled off so they can get some good reads on the mains without busting the speed limit too bad. Never tried but sounds like a good idea to me.
It's all about learning so keep going...

Todd ..I would totallt agree if they were of an unknown history. They were dipped and Wired George put all the guts in. I was a newbie then and just slapped them on the bike. The bike has ben a rider for the past 3 years as is. The reason i decided to do some snooping is the fact that Rustybronco did the carbs on my 78 E model and there was a big difference as far as the 2 bikes were acting.. They are both 750s so i would expect a close reaction from both. In this case the 78 was way more resposive and had more overall power than the 77. Well true to my intuition i found the jets all wrong and decided it has better be sorted out. Seeing that i knew the carbs had been dipped and the bike has been a rider for 3 years i only FRESHENED up the pasages with the carbs spray and compressed air to be sue anything wasnt in there. I had them apart so why not do a bit of extra swabbing was what i was thinking.Hope the history of the carbs gives you a better idea as to why i did it this way..

Ed, the setting the air screw at 1 turn comes directly from the 8 valve 750 service manual at cliffs website.

Chuck for gods sake man! I didn't know you had a thread going on this. Why didn't you call me like I told ya. Anyway. First off Wired George is an idiot. IDIOT. 110s?? 17.5??? 17.5 should never have been in those carbs. Too big! 110 is two sizes two big for stock. I wouldn't trust him to clean my headlight let alone my carbs. Anyone who says they can tune carbs to perfection without the bike they go to being there is full of ****! I don't care if he has the exact same bike. There are too many factors in state of tune from bike to bike to get them right on a bench. He may get you close (not) but not perfect as he claims. Hack. I didn't know you'd sent them to him either or I would have told ya right off you were in for it.
Anyway. Chuck those other jets in the trash. Or save em for a piped bike. The 17.5s are pretty much useless unless you maybe have pods and a pipe but even then you should be good with stock pilots.
I agree with Ed. 1 turn out is too close. The bike will tell you where they need to be like I said, but you have to go slow and you have to listen. If you get frustrated turn it off and walk away for a bit. I'm talking minute changes in idle speed.
You need to do proper plug chops. Running it up the highway will have you in all circuits and give you an over all reading, which is helpful to a point. But if you want to see what a particular circuit is doing, you need to only run in that circuit. That requires marking off your throttle positions (nothing to do with RPM!) and running the bike up the road only in that position then hitting the killswitch before changing position. Do a search lots of info on it. A plug chop will show you exactly whether that circuit is rich or lean or good. Don't go crazy trying to make it perfect or you'll spend a week. Just close. They all work hand in hand.
But, I would t bother with any of this if you've not done a valve adjustment.

I checked the valves all is well under the cover.. Like i said in the one post..I was a newbie to bike wrenching. Heck i hadnt even heard of the GSR at this point. I was told about George from a bunch of guys at bike night back in Royal Oak Mi. I had been going up to bike nights on my 98 Honda Shadow 1100 VT Spirit. Then i got ahold of the 77. This was the first bike i had to do anything other than change the oil and filters on, so consiquently i was a sucker to bite on anything and got sucked into the hype he has posted on his wbsite and now we all know the troubles and results of that gullableness. Theres a song by Tracy Lawrence called LESSON LEARNED. One of the lyrics say..lessons learned, they dont go away and they dont come cheap ..ture that!!!

Todays adventure was to recheck all the float levels and the valves as well. I think its note worthy to tell any new guys to be sure to check the float heights at each of the floats in each bowl. I found one that was bent or something and the 2 sides were way off. I had to tweek the floats so they were each at the same heghts.. Just an FYI .

Nice work chuck. Proper running carbs are about 75% hard work (checking everything before hand) and 25% knowledge (or searching out into).
Now make yourself a fuel level gauge and check the fuel level by measuring. Measuring float height is just a guess.:-\\\
I gotta get me a piece of clear tubing..but Rustybronco already suggested that as well. I got some running around to do tomorrow so i expect to come home with a chunk. I am also in the hunt for my own set of guages. Any suggestions or experiences of what you guys have is appreciated.. And i dont want to BUILD my own.. I was looking at a Colortune.i think that was the name..whatever.
