The 1985 Honda CR500 was the first year of the liquid cooled 491cc 2 stroke from Honda, and it's notoriously known as the most insane Honda factory 2 stroke ever made. The CR500 is known as the "Ping King" because of it's huge displacement, it's insane torque, and it's common characteristic of being hard to start. We bought this CR500 at a swap meet for cheap, and in today's episode we're tinkering with it to make it easier to start and ride. What a beast!

  • Hi. You might heard this already, if you are low on compression the enginge will run rich. So it might be a good idea to check the piston and ring... And also, a reed valve engine should never spit back the fuel thru the carb so i’m guessing it’s time to rebuild the reed valve... Keep up the good work, boys! 👍
  • @blainehale
    Charles remains the comedic relief of this channel. I love him.
  • I remember when 500s were sometimes cheaper than 250’s because how many people would pick them up and then ride it once, scare the s**t out of themselves and then immediately want to unload it cheap. It’s crazy what they sell for now. I also love how you guys went straight from a kx65 to a cr500.

    The exhaust leak is still there and will effect how it’s running. The pipe gets a donut and the flange attached to the motor gets a metal gasket as well.
  • @amfk8079
    The respect is large for not taking the motor out. As a die hard life long moto fan I thank you. those cr500s are more and more rare by the day.
  • @CarsandCameras
    You thought a CR500 was hard to handle? How about one that's been neglected, doesn't idle, has blown out suspension, etc😁 absolutely love this bike!
  • @GPMsEVproject
    The Big CRs were always hard work, they always oiled up if you didn't have a big space to open them up, also if I remember correctly the transmission case oil also lubricates the wet clutch so they can get messy, oh yes you might want to replace the flywheel as the magnets weaken with age/heat .. and don't be surprised if it wants new rings/piston & a rebore every few hours of use ..... for all those negatives just a few moments hitting the power band are worth all the hassle. I did notice what looked like some ridging in the clutch basket, if it's not too deep sometimes a light file can help remove them and stop clutch stick/judder. One other thing you might want to check and or replace are the reed valves, they do get lazy and stick open making for hard starting and bad idle, they are also cheap and easy to replace .. just my 2c Enjoying this content very much!
  • @speedyme200
    Yeah that's the Reed valves they're holding slightly open causing fuel to spit out through carburetor during the piston downstroke
  • @sswain833
    A restoration series would be super cool on this bike.
  • @IosuamacaMhadaidh
    Honestly I like seeing John get more confident and riding larger bikes! Nothing wrong with small bikes but seeing someone's journey into two wheels is fun for me. 👍
  • @DyckRyk
    Gotta say I am loving the longer video lengths since you guys went to one episode a week 💪💀 you can really get the details in there and Im here for it
  • @WaterfrontJustin
    Watching Ike effortlessly fire the bike is like the reel going around where the guy hands the racer his beer and fires the racers bike up for him and spins it around
  • @Ratkill9000
    Next on the list, getting a Banshee and trying to tame that beast!
  • @OGbqze
    I absolutely LOVE the intro. "I'm John, I'm Isaac, and I'm Charles"
  • @chrishoff1360
    Hey guys, check the reeds. They effect starting and performance! 85 CR500 aka the Widowmaker Always check the bottom of the frame rails for ware too!
  • @dankingjr.2088
    Big bore two strokes will always be my first love. Going all the way back to my 1979 KTM 420, there is nothing quite like that level of power in a lightweight chassis.
  • @wimvandesteeg1353
    the dampening in the exhaust is not only sound dampening, it also creates a delay and high pressure in the end of the exhaust, only this way the expansion part of the exhaust will function like it should, its like 20% more effective with clean dampening material, also means like 20% more horsepower :)
  • Wish I had my cr250r down here on base to work on, when I’m off work, love the old 2 strokes

    2001 CR500. My favorite bike I ever owned! Have fun guys! They are more fun than anything else to ride. Remember the wise words of Dave Aldana. "You don't know how fast you can go until you fall off." I heard him say those words when I was 4 yrs old and have ridden that way my whole life. I am 56 now. I survived. HAHA! Great fun!
