Same bike my brother owned. He eventually got it bored out to 850, added wiseco high compression pistons, Mikuni 29mm smooth bore carbs, Lockhart oil cooler, Yoshimura header, drag bars, bullet fairing, and pirelli phantoms. It performed very well. These are the toughest engines made.
This is my hobby as well, bringing old bikes back to life. So awesome to see a young man doing this (I am old!). You have all of my respect! Most "mechanics" would not check the valves at all due to the inherent difficulty. GREAT job!
Nice to see one of these 1970's GS750 being saved from oblivion, thinking of snagging one myself, so very much looking forward to progress videos on restoration. Subscribed! Cheers!
Im impressed with your mechanical skills and Im a bit more confident for my summer project. I friend of mine has offered free to me a 1978 GS750 thats been parked outside ( covered) for years here in Connecticut, and not running.We sure didnt have the colortune back in the 80s, but vacuum guages im well familiar with. Ive owned two GT550s Suzukis in the past, !981 GS450 EX, GS1100, and presently a low mileage vintage HD Sportster. Ive read reviews on the GS750 and they were great street cruisers.
The GS750 is definitely a fun street cruiser. Plenty of power to get yourself into trouble but still relatively tame compared to modern sport bikes. If that GS has been parked outside, I imagine everything is super corroded, but should still make a solid project and has potential as long as it's all there
It's one of the best bang for buck mods you can do on these bikes, just search GS relay mod on Google and you'll all the info you'll need on doing it yourself
I just got the title for my own black and blue, I think shes stuck in first though, ive been searching for videos on how to diagnose and your videos have been a great help with cleaning and tuning!
I bough one of these in 1978 put in electronic spark an oring chain air for front forks put on a faring sissy bar back rest, daily ride to work 78000 miles then sold it.
This was one of the very first motorcycles to be fitted with an O ring chain as stock ! I got over 45,000 miles out of the original chain on mine. As soon as the front sprocket looked even slightly worn I changed it. After 3 front sprockets I changed the rear. Did this a good few times. A new stock chain was over £100 sterling back then...One thirteenth of the price of the bike new so unless you were minted you took care of it. I tried the air front fork mod but found it more faff on than it's worth.
@@HorseMalone Our first GS750 has front air forks and they always lose pressure. Seems to ride nicely once its filled up but I have no idea what it should ride like since I don't actually have a solid reference for comparison.
Great progress! You will have to find an Antique Motorcycle Club of America (AMCA) Chapter near you to show this off. You are livin the dream. Dad's friend Stew
Keep up the barn finds and the full length videos we need more back yard lads doing this you have a new subby cheers I have a Triumph 900 95 Daytona CBR 600 rr and 2005 hyosung 250 and TT 350 dirt bike its a disease lol
Again another great vid, really liked how you tuned the carbs, never knew of colourtune, well be getting one asap. Would have been nice to see the ignition and timing. I have a 78 GS750 coming in a week or so and it has points and condensers, would have been nice to see if yours had this or if it was converted to electronic ignition.
This bike still has point ignition. Hard to show every detail on camera without boring people, but I did take off the ignition cover to double check the condition of the points and everything looked good.
It is in the works, parts have been accumulating and its currently being worked on. The goal is to get it out and riding once weather warms up here in NH.
Shouldn't the switch input (o/w) go to #86 and the power supply + go to #30? When you turn on the ignition you want to power the relay to close and supply 12 volts directly to the coils thru #87
#30 is the switch part of the relay, and is the signal that is coming through our switch gear. #86 has our full 12V from the battery www.12voltplanet.co.uk/relay-guide.html
the o/w wire that use to feed the two coils is cut as described by you. the two wires that go to the two coils are connected to terminals 87. If you want full voltage directly from the battery to the terminal 87 in the relay, then shouldn't the wire from the battery +ve connect to terminal 30? When the relay is energized, aren't terminal 30 and 87 then connected? I would think that you need the o/w wire coming for the ignition-on switch to energize the relay. hence would be connected to the relay terminal 86. ( 85 terminal connected to battery ground.)

The next video in the pipeline is another motorcycle, "Will it run?", but that will just be one episode before the end of December. After that, I'll be focused on the GS750. Thanks a lot for the patience as I try to fit this in between working full time and normal everyday life.
Hi dear. Thanks for uploading useful video but can u plz talk little slowly? I really tried to understand what u said when explain how to fix carb air or fuel scrow but I can't get it even after lesson 10 times.
Fuel screw is on the bottom, turning it in leans the mixture while turning it out richens it. The air screw is on the side, turning it out leans the mixture while turning it in richens it. I used the color tune to strike the balance between the two adjustments across the rev range.
For a lot of these older bikes, you are stuck with either eBay, junk yards, or finding another parts bike. If you are mechanically inclined, you could maybe adapt one to fit from another bike, or some quick research shows oil cooler adapters to use modern fittings and aftermarket coolers. Unfortunately, there are no real options in the way of OEM new production.
Great video, I believe I have the same bike. check my channel if you like. did you refurbish the carbs? what rebuild kit if any you preferred? I did my carbs but I don't think I have the right O-Rings and its running shotty. I'm misfiring in my number 2 cylinder. I really need to carb sync and adjust my fuel/air screws. does your bike have the short VIN # ? Mine does and I cant really get the model # for getting the perfect parts. I have the same carbs too. I just cant find the right Mikuni carb settings . Man if you can help..would be appreciated .
Carb sync and adjustments are definitely needed if you took the carbs apart and split them from each other. I'd also verify that the carb boots themselves aren't leaking and the O ring that seals them to the cylinder head is in good condition. I used a rebuild kit from Z1 Enterprises. Kit seems to have worked fine, but if you can find genuine Mikuni parts I'd spring for those. This has the short VIN. www.thegsresources.com/ gsarchive.bwringer.com/ Are good resources to search for specs, factory service manuals should be available on those sites.

Waitng for part 3!!!
Part 3 is coming out soon, wrapping up some final filming
Nice guide on tuning the carbs, the synchronisation made a big difference.

I'm excited for your new update to your bike. Please upload very soon. Watching from the Philippines
I can't promise "very soon" but there will certainly be a part 3 as it is currently being worked on
Really cool! I really like your bike! So far first two videos are great it would be cool to see you fix it up!
Thanks a lot! Part 3 is currently in the works and coming out as soon as it thaws out up here in NH to get some good riding in.
I've never seen that relay mod before! I'll definitely be doing that to my '83 GSX400
It's one of the best bang for buck mods you can do on these bikes, just search GS relay mod on Google and you'll all the info you'll need on doing it yourself
@@Dan_And_Daves_Garage found it on the website you linked. Got my relay on the way now, should start like a dream, thanks!

I'm glad you found my videos helpful! Not sure what you gear problem could be, hopefully you don't have to split the case to fix it.

Great work! I rode an 83 750 t model in the late 90’s! Kept that bike 10 years!
Great guide, love these old bikes - the GS550 is also very nice
Glad you enjoyed!
good work ,got it nailed
Thanks a lot!
Need to see that part three
My second bike was an old gs550. It was wreck but I loved it :-)
you are very smart. God bless
Great progress! You will have to find an Antique Motorcycle Club of America (AMCA) Chapter near you to show this off. You are livin the dream.
Dad's friend Stew
Thanks a lot! I did see there is a New England Chapter no too far away. I'll have to join and bring the average age down a bit.
Great job man! Your really thorough and resourceful 😎👍
Thanks! 👍
Brilliant video, very useful ..thank you
Thanks! Glad you enjoyed
Definitely space for a nice black early GS750 in my dream garage! Sadly my actual garage tells me I'd need to shift a bike first...
Keep up the barn finds and the full length videos we need more back yard lads doing this you have a new subby cheers I have a Triumph 900 95 Daytona CBR 600 rr and 2005 hyosung 250 and TT 350 dirt bike its a disease lol
Thanks! Check out our newest video on a FZR600 that we picked up. We getting feedback from viewers so we know what to improve on for upcoming videos.

I've just discovered your channel and really like it. 👍 Keep up the good work and I'm looking forward to watching more of your videos.
Thanks a lot! Part 3 for the GS750 will be coming out once everything thaws out in New England
@@Dan_And_Daves_Garage Looking forward to that and 'Hi' from Old England. 🇺🇸 🇬🇧
As someone who would like to make a "chopper", I appreciate the time you're taking to explain to us what you're doing. VERY MCUH appreciated!
Thank you!
Good job.
Thanks!
Thanks for being here !
Thanks!
Awesome video, hoping to see more!
More to come!
Perfect job my friend. 🪐
Thanks!
Very nice work Sir.
wow awesome work!!
Great video
Thanks!
Nice job 🎉
Thanks!
🏍👍👍
Did you not make a part 3 this was a good series
It is in the works, parts have been accumulating and its currently being worked on. The goal is to get it out and riding once weather warms up here in NH.
@@Dan_And_Daves_Garage Oh yea hi forgot about Weather. I am restoring a GS450 and enjoying your series so far.

Looking at the wiring diagram for the relay again I think you're right, I'll have to put an edit in the video. Good catch
Hey I just picked up a 79 GS750L. Do you have links for some of the carb specs and other tuning? It would be very helpful.

I have a 78 GS750. Rebuilt it after 20 years in the shed.
When you set the carbs, how many turns out on the fuel screws? ( not the air screws)
I set them to 1 1/4 turns out
