  1. Z50, CT70 and JDM Monkeybikes
    People act like a 1970s Honda mini-bike should "run like a tank for the rest of your life" but let's get real, it's an antique. I just want it to start and run in a barely-acceptable manner, and at its core it's a lawnmower engine, and the recurring issue with these simple engines tends to be...

    I’ve got a 2008 ttr 110 with a 128 cc big bore kit, ported head, hot cam, pod filter, and exhaust. I’ve got a size 100 main jet in it currently and it runs alright but it leans out at full throttle until the end of the rpm range. Is that an issue with the main jet or something else? And is there...
  3. CRF50
    Hey subscriber here. Just trying to get our XR50 in top shape. It sat for a couple of years with some really crappy gas in it. We took the carb apart and gave it a really good cleaning; took out all the jets, all the little springs and hardware with the float, and just made sure...
  4. 2 Stroke Pitbikes
    Wondering if anyone has had any luck with a non-chinese, non-OEM carburetor replacement for the BW80. I picked up an '86 sans-carb, and I cant find an oem carb assembly anywhere.. lots of chinese knock-off for between $15-30, but experience has taught me that these are generally garbage. I...

    Picked up a project Honda Z50a monkey bike where the PO cut into the neck of the frame to fit the OEM stock CT70 carb and intake to the 72cc upgraded top end(Z50 bottom end). Creative...Yikes. After the frame gets repaired, I will need to refit the carb to the engine & have read a few options...

  8. Z50, CT70 and JDM Monkeybikes
    A couple of weeks ago I decided to buy a '79 Honda 50. Up until this past Saturday it would start on the first kick, but for some reason the engine will only turn when I kick it and won't start. I've let the bike sit for several hours between each attempt of trying to start the bike as not to...

  10. Vintage Honda XR75 and JDM Vertical Motors
    Hey guys. I'm rebuilding a 1982 honda XR80 carb (keihin carb pc10c) and the bulbs of the float are crushed: The float level is to spec. The float needle doesn't seem to stick when I move the float by hand. The jets are new. The bike starts and runs so so, but won't idle at all. No...

    Hey guys having problems with my SSR 125 I just got a new mikuni 22mm and I can't get the bike to start at all. I confirmed spark. And I have fuel in the bowl I'm completely out of ideas. Also there is an extra hose on the side of the carb I was told it is a vent. Where is it supposed to go? And...
  12. Honda CRF110
    So after reading over a vast majority of threads I've decided to take on a build. The background on this build is it's for my girlfriend. I was paralyzed in a moto wreck in 2008 and want to build a bike like I wanted to build back then. Most importantly though, I want to keep the family number...

    So I have this 66cc kit it ran good for a while. Now it makes a bad rattle noise at full throttle and loses power, it runs fine at half throttle but slower than I know it can go and when I come to a hill there's no power. The other problem is when I let off the gas and pull in on the clutch the...
  19. CRF50
    Hello All! I've just rebuilt my crf50 engine and ran it on my bench... On idle everything appears to be fine, however, once I open her up a bit theres a fuel mist blowing back out of the carb, I'm running it without a filter, does this sound normal or a cause for concern? Thanks, Josh
  20. Z50, CT70 and JDM Monkeybikes
    I recently purchased two 1977 Honda Z50A minis. The first bike was a major beast to start until I have learned its foibles. Bike two looked great, started on one kick but ran very sluggish and had blue smoke coming out of the exhaust. The seller said that he thought it might be the aftermarket...
