    Extremely Difficult to Roll XS750 In Neutral

    Wheel spins freely-ish when it’s lifted, it definitely doesn’t spin by itself but there’s also not much resistance. I don’t really know how freely it is supposed to spin because I’m the new owner of this bike. Brake isn’t rubbing or anything.

    Extremely Difficult to Roll XS750 In Neutral

    It’s much more difficult to roll it backwards than forwards, enough that the front of the bike ends up lifting up when I try pulling it back. Bike has no problem taking off when it’s in gear.

    Xs750 Rear Shocks Replacement

    Hi all, I’m wondering if any of y’all have experience with replacing/upgrading the shocks on an XS750. The shocks that come stock on the bike handle like a waterbed, as they were designed for touring. I wouldn’t trust this bike to do any touring with, so I’m looking for something a little...

    Anyone Have RS36 Carbs for XS750?

    Wanted to see if anyone on here has experience with the RS36s, I'm looking to replace the stock CVs with the set from Mikunioz. If anyone does have them; What's the mileage like? were they really bolt-on ready, or did you have to tune them? How's the power?

    General engine question. Non xs related.

    Never seen anything like that. That is so cool, definitely would be a really confusing example for a beginner though.

    XS750 Starter Motor Power Draw

    I’ve noticed that no matter the battery, even if it’s being boosted, this thing really doesn’t like starting when I use the starter. I was wondering if that’s a result of bad coils, (this model doesn’t run on points) or if it’s just because old starter systems weren’t designed great. Keep in...

    XS750 carb tuning

    If you're running Velocity stacks and new headers you'll most definitely need a rejet. I have my 750 one up on the main and pilot jets, running Uni filters and a much more free-flowing exhaust than stock. Since you've got the same year as me you should have the same set of carbs, but I would...

    XS750 Backfiring But Not Starting

    Sorry yall, I could’ve sworn I updated this post but here’s the rundown: downsized the pilot and main jet to one size above stock, needle at stock position. Mixture screws are turned out 1.5 turns. Runs perfectly. The problem I was having with backfiring was because I was running it so rich...

    XS750 Backfiring But Not Starting

    It revs up really high on choke, around 5000rpm. If I try to give it any throttle it dies out.

    XS750 Backfiring But Not Starting

    I installed the smallest pilots I have (one above stock) and the bike seems to start a little easier now? It’s hard to tell because it’s constantly giving me different results when I try something. Once the bike is started it runs at idle for about 30 seconds before dying out. After dying, it...

    XS750 Backfiring But Not Starting

    I believe I went up 2 on pilot and 3 on main. I'll try downsizing and see what happens. Thanks to some suggestions from yall, I now have allen head screws on my carbs so rejetting is a lot faster.

    Diagnosing XS850 no start

    I have an XS750, voltage dips quite a bit under load from the starter, even with a good battery. I normally have mine hooked up to a booster when I'm at home tuning the carbs. Do the oil, neutral, tach and speedo lights dim when you crank the bike? when you get it running and rev the engine do...

    XS750 Backfiring But Not Starting

    yes, ran them with filters and it runs exactly the same without.

    XS750 Backfiring But Not Starting

    I turned my mixture screws in (clockwise) 360 degrees, and after a lot of cranking it decided to start up. I’m running pods, so my jets are up two or three sizes, I don’t remember. Now that I’ve turned the screws in, the bike will only start when it’s ice cold and on choke (before it wouldn’t...

    XS750 Backfiring But Not Starting

    Hello everyone, Just like the title says, when I crank the bike it’ll make some loud pops but it won’t start. After cranking it for a long time it will start and idle fine, but obviously that’s not ideal. When I’m cranking it it stinks of unburnt gasoline. Spark is all good, fuel is new.

    XS 750: A Tale of Carb Rejetting Woes

    Hi everyone, I wanted to make this post for my fellow XS 750 owners. Although seemingly few and far between on the internet (R.I.P. Yamaha Triples.org), I want to make this post as an overview of the modifications I made to the intake and exhaust on my bike. Intake Filters: Uni Pro pod...

    1979 XS750 won't start without starting fluid

    Hi all, As the title says, my bike won't run unless I hit it with a little bit of starting fluid. Once the bike is warmed up, it starts no problem, no starting fluid required. Don't worry, I've only used starting fluid on it a few times to try and tune it. Obviously the bike is running too...

    Xs 750 won’t start after exhaust and intake modifications

    Checked the holes, and went 2 sizes up on pilot, 3 up on main jets. It didn’t need starting fluid after the first crank yesterday when it was 1 up on pilot and stock on main. Now it needs starting fluid every time I start it, but it makes it all the way through the rev range. Do I need to...

    1979 Xs750 Rejetting: Pod filters and a Delkevic exhaust.

    I’ve already taken apart those carbs so many times dealing with other issues that I can do it like an F1 pit stop at this point lol. Just got my bike back running today after dealing with some phantom issues (my other post), so I’ll probably rejet within the next few days.
