    The KE100 was my first motorcycle and to this day, the only bike I’ve owned new. That was because my mother bought it for me on my sixteenth birthday. She spent my early teenage years denying me of my interest in motorcycles, then surprised me by altruistically giving in to my interests over her concerns for safety. I will always fondly remember her gesture. R.I.P.

    As an fan of early Japanese bikes who grew up riding them, I can tell you that the carb location had VERY good reasoning. The rotary disc valve located behind the carb made for well defined and adjustable intake timing. My first street bike, when I was 16, was a Kaw A7 250 twin. It was significantly faster than my buddy's Yam 250 twin. Technology eventually produced simpler ways to make power. But in 1967, rotary valves were king!

    @Hagerty...You guys are absolutely great and such integrity amongst you. Thanks so much for all of this wonderful entertainment! I really enjoy watching your work. Please keep doing these videos! I saw in the video on the Volkswagen that some viewers had suggested some of your work taking the Volkswagen engine out was cheating. Davin Recow is not and could never be a cheater; his work speaks for itself, just watch the videos!

    I really enjoy these: the original videos and these BTS breakdowns. It's great to have Hagerty spotlight what you're into. That Davin is both knowledgeable and humble makes these videos particularly great for me. I always learn at least something. In this case: mineral spirits bath. The video work is fun in this one, too. Thanks Hagerty. Makes me want to work for you.

    I found a junked 1978 KE100 back in 1997 with a seized up engine (a lot worse than you guys rebuilt). I bought it for less than $30 and took me more than 3 months to source out all new old stock factory parts (engine parts, exhaust, wiring harness, switches, handles, steps etc.) and another 4 months to fully restore the bike on my own except for the machining and the sandblast and repaint of the chassis. My project build was later featured in local news here in the Philippines. Now, I still use it for offroad, trail and leisure rides and for some quick errands. i never had a single major breakdown at all.

    Good job guys.Couple of things I would add for anyone doing one of these. There are very few of these in the condition yours was .
    All the ones I've done in recent years the LH main bearing needs replacing. You should be replacing the seals anyway. Pull the LH seal Before you split the cases, clean the shaft and the grove where the shaft and bearing join very good to prevent scratching the shaft when it comes apart. Check for a good fit of the bearing race and shaft, if the inner race can spin on the shaft you need a new LH crank half. When you install the new seal see that it does not cover any of the oil hole (I notch the seal a bit to clear it). Most parts for these engines are still available from Kawasaki and the Fort Smith, AR dealer.

    Nice video with a special connection for me!
    I learned to ride in 1972 on a yellow 1972 G-5 100 which was the precursor to this one. The official top speed was 66 mph but the particular instance I rode could hit 80, as clocked by a car travelling alongside. Of course, we only weighed ~125# at the time so it wasn't overloaded and I can't say the road was 100% flat; there might have been a slight grade to it (but not much).
    The great thing about it was that it was just about indestructible! At least three 15 year-olds learned to ride on it, from scratch and we rode the daylights out of it. It was jumped over 70' horizontally and 10' vertically (on the same jump) which cracked the front hub from side to side. It still rolled fine but you wondered when it was going to let go completely! We also sheared the foot pegs off with hard landings.
    Unfortunately, it was eventually stolen and that was the end of that.
    I hope some day to have a collection of 1972 Kawasaki trail bikes from the G-4 to the F-9 (it's weird that the 350 was F-9 but the 250 was F-11!) to go with my collection of Honda Motosports.
    The enduros of that time are what the motorcycle industry needs today to save it. If you don't sell something a 12 year-old can dream about and a 15 year-old can save up for, you're not going to get life-time riders. Coke and Pepsi understand the importance of those years. You also need a seat height that works for a kid with a 26" inseam.
    I see others have commented about the rotary valve input explaining the carb position so I'll skip that.

    • @peterholthoffman
      @peterholthoffman 6 років тому

  • @TheAlpineProject
    @TheAlpineProject 6 років тому +2

    The rotary disc (or rotary valve) can be opened up to essentially allow more fuel timing. A clever fella down under even made a variable version for a Kawi Bighorn.
    Also if the crank seals are original, they're likely letting air get sucked in and causing the bike to run lean. 2 stroke preoiler systems often get blamed for what's really an engine leaking vacuum. Rigging up a vacuum tester and finding leaks is well worth your time if you haven't, otherwise you might end up doing another top end rebuild.
    Regardless though, nice video.

    • @CWS1963
      @CWS1963 2 роки тому +1

      Nice comment, as an ex Kawasaki wrench from the late 70s to 90s I was saying the exact same thing watching this. That piston died from being lean, and it's rarely the injection system that is the culprit. Cant count the number of Kaw 2 strokes we saw with the pumps disconnected.

  • @LaxDave9999
    @LaxDave9999 6 років тому +2

    Hi, I enjoyed the video. You all seemed mystified as to why the carb is on the side under the side case? I am pretty sure that this is a rotary valve intake system. At least my trail boss 100 was, and I thought most all of the small displacement bikes of this era were? I could well be wrong, as I am not expert. But, also, I thought I saw the cover for the rotary valve once you all got the rest of the side cover off? You all did not take it apart, however. With the rotary valve, it was easier for Kawasaki to just mount the carb on the side, versus doing what can am would do later which was to mount the carb behind the cylinder with a intake runner down to the rotary valve.
    Great shows, thanks again.

    • @saksittichompoo3583
      @saksittichompoo3583 6 років тому

      My first motorbike was a Yamaha YG5 with 80cc displacement. It used same rotary valve technology. It was pretty popular tech for 2 strokes-engine back then. The constant valve opening made the engine to have good engine power at certain engine speed.

    • @ericmiller9132
      @ericmiller9132 6 років тому

      Yes, this is a rotary valve 2 cycle or 2 stroke engine, depending on your preference of description. During the late 1960's through the 1970's, manufactures used all types of induction on their trail bikes, with reed valve intake becoming the most popular due to it's simplicity and cost. Kawasaki stuck with the rotary intake system on the KE 100 through its lifespan. The rotary valve system allows for the widest power spread across the RPM range but it is more complex. Reed valve induction is really no more complex that piston port induction but allows for more low speed engine torque, so a nice happy medium for the cost.
      Can-am (Rotax) engines of the 1970's were always ranked very high in usable horsepower delivery in magazine tests and usually delivered the highest HP output on the Dyno as well.

I'm still new in this restoration thing. is it really possible to machine the 2 stroke engine block to fit a new size piston?. from what I'm inform that 2 stroke engine block have a thin coating on block wall (molybdenum) I guess, that made on the block. so than if you machine out that thin coating and block itself to resize your block to fit new piston, the block won't be good and will not last longer. is it true ? .
    any reply I be appreciated. just want to improve myself to be better.

      Watching the video they explained the reason for the "rebuild" was basically it was a bike that was just laying around, so no real expense. Since most people have never seen a rotary valve 2 stroke, it provides some educational value.
      Would have been more educational if they would have performed a full rebuild, split the cases and such. Old dried up crank seals can cause a lot of tuning problems, but are offend overlooked.
      As for better candidates, anything popular already has 100+ videos. Don't be too hateful, these bikes are like fat chicks, they're fun to ride until your friends see you with them! :)
