I think your bike is a classic the way it is and is also in a class all by itself.Enjoy the nostalgia of the era in which it came from.If you want to "hang with crotch rockets"by a crotch rocket.Your bike is 27 years old, ride with pride! Got any pics, I would like to see it.I just purchased a 79 750L myself.odl777 said:

Spend your money and time on developing your riding skills and upgrading and tuning the suspension, not the engine.
Then lure the sportybike scum out to the twisty roads and have your way... bwahahahahaaaa!
When the road turns twisty, speed is determined by the rider's skill more than anything else. While not blessed with a modern bike's magical suspension and chassis, an old GS can be turned into a stable, predictable platform for a skilled rider. It's a lot more fun to lose the squids on an heavy, underpowered old GS than it would be on a bike comparable to theirs.
Any moron can twist a throttle.

true but i get tired of getting no respect from the rocket scum they think my gs is just a piece of crap. I am also a teen and this is my first bike and i hate that no younger guys appreciate this great bike, but i do got it were i can hang with an older rocket a little better.
I do focus on getting the suspension tight i have recently stiffened my front end and bought some rear performence shocks.

I have to agree - enjoy what you have. You've pretty much maxed out the performance that you can get from this bike, any more would be money poorly spent in my opinion. Today's crotchrockets are MUCH lighter (stock your 79 750 probably weighed in at 475??, new 750cc crotchrockets can't weigh much over 350, if that!). You've got 2 valves per cylinder, they've got 4. The engines are much, much lighter, and I have to believe that engine theory has come a long, long way since 1979. Your bike was made only 10 years after the very first in-line 4 cylinder motorcycle engine was introduced - and only 3 years after Suzuki started producing it! Suzuki and the rest of the Big-4 have had almost 40 years to tweak the design, to lighten every component, to use better materials, to experiment a lot more with cam configurations - things that just weren't possible in 1979. And the v-twin crotchrockets are another story all-together. Much more powerful bottom end and very torquey. I rode my 83 750 with a guy that had a new SV650 last summer - the guy made me look like I was chained to tree when we took off from stop-lights.
Now - that being said - there's one more thing you may want to play with next time a sprocket/chain change is due is to get a bigger rear sprocket or smaller front sprocket - or both. You'll be able to accelerate a bit quicker. But nothing too major.
And also - just realize that your 79 750 can still pretty much take any car on the road - from the 70's OR today.

keepin Up with the Jones...or the race rep guys, I know what your saying, I dont get much repect from these young guys, but it all changes when I show my ability on a bike thats twice the weight of there machines, im not pulling my own chain, I dont think Im a particularly talented rider, but alot these people get a new bike every year, and its more about what they have in there wallets than riding ability...
ride what you have, enjoy it, dont let anyone tell you what you have is ****e, maybe if wanna improve the handling try a front and rear suspension upgrade, focus more on your ability as a rider, and know your limitations, and try to ride within them.

true, about all i still cant beleive these beasts are as fast as they are, i couldnt imagine this much speed in the 70's.
with my bike i can usally take any v-twin but i havent raced a sv or anything. I have raced my brothers 883 2005 harley with a 1205 big bore kit highperformence ignition with performence cams. he said he couldnt even here his bike and it was neck and neck all the way to a 100. it was intense!

Just saw your most recent post - don't worry about the guys who think your GS is crap. Those are the younger guys who are probably struggling to make the payments on those bikes and ride way beyond their skill level - not really a good crowd to hang out with when you're learning.
You'll meet a lot more interesting people when you ride this classic GS and get approached at a gas station by someone who compliments it or used to own one.
You'll learn awesome riding skills too. Learn how to maneuver these bikes properly and a newer, lighter bike will flick around like a toy to you!
And these bikes have what crotchrockets don't - that old-school feel and old-school look. OLD SKOOL BIG DOG!! OLD SKOOL!! Ride it with pride! Hell- slap some lower bars on it, rig up a cafe fairing, get some leather and a pair of old-school goggles and ride it with an attitude brother!!

Way ahead of you i have put soem cafe bars on it and even painted it myself like an oldskool cafe. Its a flat laquer black with a metalic gold racing stripe down the middle wtih two little pinstripes on the sid eof that. i also have recently got me some red barron goggles and an 80's leather jacket with a PJ1 racing patch on it. i love this bike i just wish more guys my age would appreciate it, maybe its because i never let them ride though either.

HA! I'm not kidding when I say this - you just made my frickin' day. I thought I was going to **** my pants when I read "red barron goggles". I just imagine you riding on some New Mexico desert road, crouched up hugging the tank with those goggles and the vintage jacket - peeking over the cafe fairing. I'm thinking maybe a scarf as well?? LOL! LOL!! You've got some real character my friend - this is awesome.
I'll tell you this much boss - if you ever ride that thing on up here to Ohio, you send me a PM. It would be an honor to ride with you. Tour the twisties of southern Ohio oldskool style.
I BEG you to post a pic of the beast.

What a beautiful bike! Take pride in the fact that you've got a bike with character and style. The fact that the racer wannabes don't realize when they're being out-classed just makes them all the more pitiful. Speed isn't everything, especially on the street.
I often ride with a guy on a modded ZX1100, Andy on his FZR, Fi on his hopped up GSXR, and another guy on a Blackbird... the only thing I need to do is pay real close attention to what they are doing. If they go to pass a line of cars and I miss a second or two, they pull away real fast. But if I pay real close attention (with my eyes and ears) and I react as quick as possible, I am right there the whole time.
If a good rider on a late model 750 wants to lose you, it will happen. They are much faster, lighter and effecient than our old GS's. You could spend a couple thousand dollars on hopping up the motor, but is it worth it? If it's that important to you, maybe find a newer sportbike.
But remember- someone is always going to be faster than you.

the speed is not so much important to me i just want to show the newer guys how good of bikes these are. I have raced a few guys on rockets and they were a little impressed after i told them what year it was. I just love it when one them over revs or misses a gear and i stay even closer on there tale.
alot the young guys on rockets cant even work on them so they dont hardly have any mods and they pay others to do there work. im 20 and have done all my work top end rebuild, welding, modifying, painting and upholtstery. all togeather with the price of bike and all mods it cost me a toal of about 1700.00. Can you beleive my parents still wont let me bring it to college.

The old 2 valve bikes just can't make the power of todays rockets. Not cc for cc. Handling has improved a lot too.
You can still have fun on your bike and surprise someone now and then as you've said.
What I can say is to be sure the jetting's correct, among other things, to get the most out of the bike and for it to run its best.
You mention the mains are 118. If you have the stock VM 26 carbs, stock mains are Mikuni 102.5. Also, Mikuni doesn't make 118, just 117.5. and increasing/decreasing in 2.5 increments. So I'm guessing you may have some DJ mains?? Seems a little lean to me because a 118 DJ jet is roughly the same as a 107.5 or 110 Mikuni jet. Different makers number their jets by different methods. That means you've only increased the main about 1 full size up. Not enough for pods and a pipe.
If the bike has good compression and is in good tune otherwise, it should use something closer to 120 to 125 Mikuni mains, depending on pod filter brand and pipe flow quality.
Also, and even more important to general riding, you need to raise the jet needles if it hasn't been done yet. If their e-clips are still in the 3rd position, you're lean for sure. Then you'll need to richen the pilot circuit too, but may get away with only pilot fuel screw adjustments.
I mention this stuff because you only mention changing the main jet, a common mistake by many. All 3 jetting circuits must be richened and the carbs vacuum synched after. Before any re-jet, check ignition timing, valve clearances, etc.

My bike is a little newer than yours but will keep up with most newer bikes until up around 125 or so. There was one guy on a Gixxer, not sure what size, that was on my tail on a freeway entrance ramp. I hammered the throttle and left him sitting. It wasn't until my bike ran out of legs that he caught me. As he pulled along side he looked a little dismayed that my old 700 had just pretty much outrun him.
thanks for the reply i had no idea about the dj thing. Lokks like im going to have to do some adjusting to the carb. on checking the valve clearence do i just use a feeler guage and measure the beearing and the shim and if it is off do i get new shims.
I have a bandit titanium header on the bike with no muffler been wanting to get a little slip on tip like the ones on race bikes. the pods are a cheaper kind not k and n but seem to work fine. thanks for the tips and if you have any more let me know. wish i could find someone in the nm area to help me out with this stuff . thanks again.
