    My father had the 2nd GT750 Suzuki in South Africa in 1972, also later fitted with expansion pipes & tuned accordingly. In 1977 he traded it for the 1st Suzuki PE250 in the country. I got plenty of pillion time on the GT750 in the day. The handling problem with almost all of these early bikes could be sorted easily today, with stronger box section swing arms, with bigger bearings & bigger triple clamps up front.

    I owned a Kawasaki 500 triple in the mid1980s and I rode it hard. The electronic ignition went out and at that time nobody stocked a replacement. I was busy as an Army soldier so I sold it for parts. It was a hoot when it was running.

    I used to have a 1979 Yamaha RD400 that had been heavily breathed on. A friend had a Ducati 916 and he could never shake me. That RD eas one of my favorite bikes and i never rode anything close to the kind of acceleration it had until i bought a BMW S1000rr in 2013.

    2-strokes forever!!! When i was a kid, i only needed an exhaust tube and a big carburator, the rest of performance i did it by filling, porting and motorhead rework for higher compression ratio....done!!! We didn´t had the money but we wanted to be fast. This April 2023 my Puch 50cc from 1980 will resurrect from the ashes. Cool channel, greetings from Spain.

    Yeah that Titan is lovely especially the longer wheelbase. I’ve always loved those Scott Squirrels too. Another appealing factor for two strokes is no expensive valve clearance issues to worry about at service time. Just new piston & rings along with big & small end bearings say every 20k and all was well. Micron/Allspeed pipes add extra magic too.

      I remember in 2005, coming across a small disused Diary factory (I had run out of fuel and was looking for the farmer to bludge some) here in NZ, jam packed with Morri thous🤮😆and.....about 15 old 70s early 80s bikes. Most were GT380s and 550s, with about 3 GT500s, and 3, RZ350s, all 1983 models. I ended up going back and buying the RZs and the old guy gave me boxes and boxes of spares, engines, pipes, powervalve servos, forks, just loads of bits. Went back about 8 years later with a guy who was into GT Suzukis and the place had been turned into really flash home by a big city type, he said the old guy had died and he bought the property off the family and he had a scrap dealer remove all the "old junk" before he started the renovations.

    500 was called a Mach 3. I loved mine. Cruise at 70 mph all day long, vibration free, and excellent fuel consumption. Gave an E-type a hiding through the Blue Mountains on one trip. Moved on to Z1a, which was just no. 1. Also had a 550 ram air for a while. Another excellent highway bike, butnot sure how you could fall off it. Had z bars, which looked ridiculous but bloody great for highway riding. A very underated mc.

    In my day we used to have a saying there were two kinds of Kawasaki riders the quick and the dead. Either you mastered the beast or The beastmaster you. All of the Kawasaki triples had more engine power than the frame could handle. Suzuki two-stroke triples of the same kind were much more usable watch horsepower but better reliability and better ride quality. I rode someone's Kawasaki H2 750 on the highway and I gave it gas and nothing happened I gave it more and suddenly the front wheel was off the ground and I was trying to hold on to the bike one ride was enough for me.

  • @lorditsprobingtime6668

    Oh man, you got me! The whole way through I was reminiscing, including the Kwaka 750 triple a mate bought, let me ride then came back with it a few months later for me to ride again after boring, porting and expansion chambers fitted to road race it. Both times I was blown away by the crazy power and how it delivered it, the second time, with limited suburban roads I never could quite get to full throttle, AT ALL! Those things were brutal but just the feeling of it had me taking it really easy on the bends, it felt horrible.
    Where you really got me was that I did own a GT 550 too, quite a few years later I wound up with a T 500 too, the longer wheel base one. I was going to try and compare them but, totally different type areas where I was living plus, probably 10 or 15 years apart but, I've always had a real feeling for that T500, even though it did try to kill me by locking up the rear when fifth gear pooped itself and the gear flew apart locking the rear wheel up, just as I was pulling back in front of a truck I'd just overtaken at around 140 kph on the inside of a bend! That forced me to spear straight off into the scrub to get out of the way of the semi, though, even then, if it really wanted to kill me, it would have locked the rear wheel while I was beside him and that would have been it. As it was, I skidded to a stop, somehow still upright but, that was the end of the T 500. I know I could probably find parts NOW but, this all happened some years ago, before the internet opened the world up the way it has.
    I always had an impression the T500 a little quicker but, no real way of directly comparing, just old impressions. I remember the 550 GT as fun, fairly quick, mine did have the disc brake front, a digital gear indicator, which I really did like. I'm one who'll keep checking every few miles to make sure I definitely am in top gear, derp lol. It also had reasonable handling but, a bit of a bloated show pony. It had racy looking stripes, their fancy ram air system (mine used to start seizing up if I flogged it too long) a lovely big wasteful set of FOUR mufflers! For 3 cylinders!!! It tried to look too pretty at the expense of adding useless waste and gimmicks. The old T500 was a kind of honest but agricultural looking bike by comparison and it never disappointed, well, except for that one time lol. I loved that it looked so basic by comparison yet went pretty good. I loved that several times I had it drifting pretty hard around bends, probably would have lost it on almost any other bike, not the T 500 though, I never came off that once, not even when it blew it's gearbox!
    I more recently owned a BMW S 1,000 R and oh man, have modern bikes gone k ray zeee now lol.

I bought it used and it had a bad crank seal which lead to a burnt piston at 25000kms, I changed the seals, piston and re ringed it and it never gave me problems again. I sold it with 75000kms on the click and it still ran like new.

    Love the videos! In the day, I rode both the H1 and H2 Kwackers: The H1 was truly deadly, with frightening frame flex in fast bends. The H2 was better but still awful in anything but a straight line. Much nicer engine, though.
    The Suzy 3s were really good bikes, and I know as my dealership sold both Honda and Suzuki. The Water Buffalo would run forever with little attention, but it was rather cumbersom. Interestingly, the only big 2-stroke I ever owned was an unusual Suzy Titan; "unusual" in that it had started life as a TL500 racer that got street-ified. The frame differed a bit from the production Titans, and mine had been gusseted in strategic spots. I kept it until the late-1980s, and it was still quick and did well on then-current "DOT" racing tires. However, it was loud beacuse of the chambers and comfort was not a consideraton...but, on a curvy road it was hard to beat or fault.
    I had the chance to ask a Suzuki factory rider (who shall remain nameless) what he thought about the RG500: his response was that he rode the GP bike because they paid him a bunch of money to do so, but he could not understand why anybody would pay THEM to ride anything like it! Reminded me of Kenny Roberts famous statement after having won the only race he rode on the TZ750 flat-tracker (1975 Indy mile), "they don't pay me enough to ride that mother f*cker again!".

Then you had to triumph BSA triples and the Honda 750 four cylinder as well as to Norton commando and the triumph Bonneville we're still hanging on. Some bikes would have the same displacements but vastly different character and temperament.

    Some time ago I helped a guy put a RG500 motor into an RGV250 Frame.
    He even went to the trouble of having the bike Engineered so it could be Road Registered.
    Back in these days the Great Ocean Road was our well known race track.
    Of course that has all changed now, and has become a fairly civil road to ride on.
    Mostly reserved for the Cafe Racers and tourist who think the Great Ocean Road ends at Lorne, LOL.
    You definitely put together a great video.
    Looking forward to watching the video about my all time favorite bike .
    The Kawasaki GPZ 900R.

    Big pistons are fine, but how did you increase crankcase displacement? A larger bore displacement requires a larger crankcase displacement..
    how are you Increasing the ability to fill the larger cylinders through tiny limited transfer port area?They can only pass so much per stroke..
    any detonation problems? How much did you have to lower the RPM limit? How much heavier than stock is each piston/rings?
    I owned a Factory Kawasaki road racer. An H1 R..Sandcast cases, cassette close ratio five speed, the Bores of the cylinders were chrome, it was a piston port intake system, and it needed the crankshaft replaced regularly.
    I bought a crankshaft from that guy that still writes for cycle world or cycle Kevin Cameron who was supposed to be some kind of a guru. He would not ship a rebuilt crankshaft to us from Boston to Pittsburgh. He insisted it had to be picked up in person because it was such a precision made perfectly balanced crankshaft that he had rebuilt.. so a friend of mine and I jumped into his Vega, and drove 22 hours up and back to pick up this perfect crankshaft. When we got home, that crankshaft was so out of true, it would not even sit in the cases..
    on the Yamaha TZ 250 D that I had, the crankshaft needed to be replaced every 1200 miles, new pistons and rings every 600 miles. That was a 54 mm stroke 54 mm bore engine, I think. What is the bore and stroke of this engine and how long do the Pistons even last? I know that a 10 ounce piston and rings in a 54 x 54 mm engine two-stroke at 10,000 RPMs, that 10 ounce piston and rings weighs over 2400 pounds to the wrist pin..
    lots of development problems to overcome just to get it to run let alone get it to survive more than one heat cycle without it self distructing..
    Quite a feat

      you have the right idea jody fresnack...the only bike I modified was an rz350 racing against fz400s, went up on piston size and porting...first race of the year and it seized, was hoping to better my 7th place overall of the prior year...other than that, I just rejetted, tires, suspension and gearing, no touch the motor please!

  • @maxxpretzy2557

    ...excellent research! Personally, I always thought I preferred the 500's from Yamaha and Suzuki but had to settle for the Yamaha rz 350...which turned out to be my favorite of all my sport bikes even over my 1997 gsxr 750 chassis with an 1128cc gsxr engine, on track and public road...most crotch rockets are overkill for public roads, even the 400cc machines, as were the 500's 2stroke back then...rubber side down please!!!

    What is not to love simple powerful and light. Everything a 4 stroke is not. 500cc four makes 200hp. 4 stroke needs 1000cc, 500 smaller lighter thinner. 4 Is okay but even 20yr old 2 stroke at half cc's makes as much power, and revs much quicker

    I’ve got a Scott DPY I’ve got the engine running I’ve just got to do the rest of it yet. I know it’s a long-term project it’s got the nickname fuzall a friends, little girl overheard me, her grandfather talking as she said to her mum she was only 4 Why is mikes bike called Fazall so my mother heard this they said I don’t care what that is its name so there we go.
    I know they were singles but Ajs stormers. I’ve got a big part of my life. I spent lots of time at the factory working and building them so that’s good. I have a part of my life my leg doesn’t allow me to ride the competition bikes anymore, but I still love playing with them and one day. I will get faster on the road. Enjoy your program Michael

    Your mistaken on your h1 spec info.
    You he early H1’s top speed was 125mph (not 120mph) & 1/4 was in high 12.90’s (not low 13’s) & could beat the Honda 750 in 1/4 runs stock vs stock bikes with experienced riders.
    I also experienced that 1st hand wrenching & owning mult H1’s & racing many stock & lightly modded Honda 750’s with my stock h1’s and beating them every time in 1/4 mile runs,just never bothered to race top end to top end so not sure of that outcome.
