  • Go-ped restoration

    Hi everyone, just joined this community today.

    I came into ownership of a Go-Ped GSR40. I was browsing the free section of Craigslist and happened to come across a non-descript listing for a run-down Go-Ped, and and what do you know, half an hour later I became a proud owner of a new-to-me Go-Ped! I didn't really know what I came across (nor the owner or he probably would have sold it for cash), until I got home and was able to look up what exactly this thing was. But from what I understand these things are pretty reliable and have held up their value over the years.

    Here are some pics:

    I'm planning on restoring and bringing it back to life. My only concern is doing irreparable damage to either the body, paint, or engine. I have some mechanical experience, but not enough to confidently know what I'm doing. Exactly how valuable is this thing? I'd like to work on it as a project on the weekends, but if it is pretty valuable I would feel more inclined to have a professional work on it from me. I don't want to damage it and potentially hurt its resale value down the line

    From what I've read, 2 stroke engines are pretty straight forward. The fuel lines and filter would definitely need to be replaced. The carburetor probably needs a rebuild, or an outright replacement/upgrade. Someone on reddit mentioned that the stock carb is most likely not worth re-building. The frame seems strong, but the steering fork seems wobbly.

    I reached out to Go-Ped and all they provided me with a service manual (http://www.davesmotors.com/site/file...ShopManual.pdf) that wasn't that information tbh. Anyone know of any guides to restoring old motors? Preferably one for the G43L-D, since I would most likely need a step by step guide.

    Any thoughts or recommendations would be really appreciated!

    Thanks!

    Congrats and welcome to the forum. Gsr40s are great gopeds, arguably the best scooters Goped ever made. I own all flavors of the gsr40 from bone stock to fully modded to the point the only original part is the frame itself. They are all fun.

    Don’t worry about hurting the value. Just have fun with it, do whatever mods you want, make it your own.

    there are a couple things I would suggest right from the start however (in addition to regular maintenance like fuel lines, etc)

    1-adjustable carburetor (from ADA)
    2-bigger front sprocket (I run a 9T, 180lb rider)

    You can also modify a cheap eBay carb to fit (they are adjustable) but this takes some know-how as to what you are doing.

    Stock 40s will do just about 40mph with the bigger front sprocket and carb on flat ground with 180lb rider.

      Thanks dsport.

      I'm still having trouble getting this thing to start.

      I've replaced the fuel lines, filter, and the carb bulb. I took the spark plug out and did a test pull and saw a good amount of sparks, so the ignition system seems fine. Spark plug is dry.

      I took off the air filter, and put my hand against the velocity stack and felt some suction.

      Fuel mix I'm using is 40:1, 91 octane. I'm in california, so all our gas has 10% ethanol.

      Other than getting a new carb, not sure what else to try next. I'm hesitant to buy a new to buy a new carburetor, since I'm not even sure if this thing will run. Granted, I think most of my bases seem to be covered and I might just have a clogged carb.

        It’s usually always the carb, I bet that’s the case with this one too. Also 40:1 isn’t quite enough oil, I’d add some more oil to the mix, go with 24:1 in the future.

          40:1 is an appropriate oil ratio for a stock G43LD motor. Any additional oil is only lowering the octane rating of the fuel. More is not always necessarily better.

          OP, congrats and good luck with your project.

            I suppose if you’re completely stock, but keep in mind 40:1 is a recommendation from zenoah for lawn equipment use. I personally just like the piece of mind knowing my motor is lubricated. But to each their own.

              Thanks for the tip, I did slightly higher ratio than 40, I went for 30:1.

              I was able to get this thing working with the stock carb. I just had to hit the gas a bit as I pull started the engine. Couldn't determine its max speed cause I was afraid of flooring it for too long without protective gear.

              This thing runs surprisingly well for being 18 years old, with its last tune up being many years ago.

              Thanks again

                If your ratio is correct and the carb is tuned correctly, your motor will be sufficiently lubricated.
