    I agree .... The stock exhaust system for a Suzuki. GT 550 sounded pretty dam good ,,,,,,, I’m a 2 stroke guy ,,,,,, For life ,,,

    Sounds great. My only issue with the GT550s was that they are very viby bikes. So much so that they will put your hands to sleep. My GT750 was so much smoother and of course the power was very good. 🎉

    Thanks for the video. My first motorcycle was a 1975 GT550 in 1980. I tuned it up until it was running perfect and then went to an abandoned dead end road. I ran it through the first three gears and it blew my mind how fast it was off the line! Great memories

    Had the identical '75. Loved it - traveled from Jersey to Utah on it. A few years later I came upon some J&R Expansion Chambers. I put them on and it was like Jekyll and hide. Wheelies on command and. lots of noise. Too much noise. Glad I kept the stock pipes for the long trips.

    A GT550 with a 3 into 1 is the best sounding bike ever. It sounds like a formula one car from a distance. I know its not efficient but the sound is awesome.

      I traded my 125 trials in for a 550 with a 3 into one. After a couple of months the baffle blew out at speed on the motorway. The bike was so much faster after that but far too loud. Put a baffle back in.

    After I had a Waterbuffalo 750 upgraded with expansion chambers, K&N Filters, and re- jetted by the Suzuki shop, it burned a hole in the piston of the middle cylinder. I would never mod a 2 stroke again. That work was done by Suzuki...

    • @vintagecycle316
      @vintagecycle316  ปีที่แล้ว +5

      Great question. Running the stock airbox and stock Suzuki air filters, it doesn't appear the expansion chambers have changed airflow enough to require a jetting change. I was at first scared I would be running much leaner now, so I checked all 3 plugs after about a 5 mile run on the new exhausts and all had the proper tannish brown appearance. Cleaned them, rode another 15 miles and checked again...same tannish brown appearance. Before this, I don't believe the plugs have been out in several years, so possibly I was a bit rich before..dunno. I'm sure if I went to pod air filters I would certainly need to rejet, but I like the look of the stock airbox.

    • @dogshome7110
      @dogshome7110 ปีที่แล้ว

      ​@@vintagecycle316keep the airbox, all sorts of issues without it. Don't trust a plug chop for mixture though. A high load for more than a few seconds will find a slightly lean mixture in holed or melted pistons. Just a seize if you are lucky. Get a wideband O2 sensor to be safe. Spanneys do change the mixture.

    • @RY-kx1xp

    @Ratbiker 8 หลายเดือนก่อน

    Did you ever get the jetting figured out? I just bought a set of Higgspeeds for mine. After doing some research, I believe the bike will need 110 or 115 main jets; depending on altitude/climate, and if you have done any air box/filter modifications.

    • @vintagecycle316
      @vintagecycle316  ปีที่แล้ว +1

      I've done several plug chops with the bike after the exhaust swap. Plugs look good with no signs of running lean. I believe this is due to the fact that I am still running the stock airbox with factory air filters. I imagine if I swapped out for some K&N style pod air filters, the carburetors would require some jetting work. I've ridden less than 100 miles still since the swap, so I will plan to look at the plugs a couple more times to be sure. But as of now, all looks good to me.

    • @nickwiley480
      @nickwiley480 ปีที่แล้ว +1

      @@vintagecycle316 yeah good thinking. I had the RD250 and fitted Allspeeds to it and a K&N filter in the standard air box and the plugs looked fine but every couple hundred miles the piston around the exhaust port would break up.

    Higgies! Love it. Now it sounds like it means business. The two stroke triples have a great sound. Very different from my Yamaha twins.
    That's a nice vintage machine.
    How is the parts availability with the GT's? The Kawi guys are having a rough time with parts. Yamaha, on the other hand, has good parts availability. I would like to add either a Suzuki or Kawi triple to my collection, but the parts situation worries me.
    Ride safe.

    • @vintagecycle316
      @vintagecycle316  8 หลายเดือนก่อน

      Pre-2020, parts availability direct from Suzuki was great. But during the pandemic they started discontinuing all the parts for older bikes. Now Suzuki sells very little for the GT bikes. But there's a pretty good aftermarket following for most items you could need such as rubber bits, engine internals, and other commonly needed items.

    • @Scott-ph2yk
      @Scott-ph2yk 8 หลายเดือนก่อน

      @@vintagecycle316 So you can get access to crank seals, piston kits, brake parts, etc. Good to know.
      Today, I am spoiled by good availability from Yamaha for RD's, supplemented by other sources. Long term, I expect eventual discontinuance as demand decreases. I love the 70's and 80's bikes. Something there for everyone.

    Cool video. Usually I hate 2 strokes because they sound like an angry hornet buzzing down the road. But I'll make an exception in this case because the Suzuki GS550 is such a classic 2 stroke and it sounds like 3 angry hornets buzzing down the road 👍
    PS - I had several 90 and 100cc bikes over the years. All 2 strokes except for my Honda S90 which was my favourite. There is just something about a 4 stroke that is soothing to the nerves.
    PPS - I subscribed to your channel because you have such a wide variety of cool bikes. I am going to watch the Suzuki RV90 next. Lol.

      :-) Thanks for your thoughts. I suppose we all have differences of opinion on what sounds and looks good to us. I love an all original motorcycle, and have several all original Suzuki's. But to me, the sound of 2 stroke motorcycle on expansion chambers is music to my ears. And I still have all the original pipes, and no permanent changes were made...so it can be put back to original anytime down the road if I decide too. Thanks for watching. I appreciate the views and comments.
