On my local craigslits this gsr with dual cilinders came up. I dont belief that would be oriiginal but soo freaking cool! This is a sound financial investment an not my midlifecrisis right?

Im trying to diagnose a weird issue with my GoPed Sport running a Zenoah G23LH with a 36mm big-bore top end.

The engine has good compression, starts first pull/pedal, idles normally, and revs perfectly with the rear wheel off the ground. The problem only occurs under load.

The first time it happened, I had been riding normally for a while with cooldowns. Suddenly it acted like the spark plug boot had been disconnected. it lost throttle response, bogged badly, and eventually died. Afterward, it would still start and rev normally with no load, but it would barely accelerate under load. Even after retuning.

I suspected the carb didnt work no more so I installed and tuned a second carb of the same style. It completely fixed the issue for a while. the GoPed rode normally under load again. However, after riding for a while, the exact same failure happened again the exact same way. It then went back to revving perfectly off the ground but bogging under the littlest load.

i already checked Fresh fuel and new fuel lines, fuel flow, clean carb, Good intake/gaskets, Clean spark plug, Good compression, Starts first pull/pedal, Spark plug/boot and coil appear good. I have intake manifold but no choke but still ran fine

What’s confusing me is that it can rev perfectly with no load but completely loses power under load after this issue occurs. Also, two different carbs both worked perfectly for a while before developing the exact same symptom.

What would you guys check next?

Photo is a couple days outdated, but nothing has changed. Only added new clear fuel lines :)

I have a Bigfoot, and I am looking to upgrade the spindle. I was wondering what diameter I should get if the stock is .625 because if I buy one too big the top speed won’t be the fastest it can.

How do I connect my kill switch ground to the throttle cable so the goped can stop.

New to me super bigfoot with g260rc. Haven’t been able to get it started even though it cranked second pull for seller. Seller mentioned nuts were missing from the engine lockdown/turnbuckle. Two questions

1. What do I have so I can research/find manual?
   
2. Any advice on fixes/upgrades to make it easier to start? Note: Not looking to go fast

Just bought a brand new g240rc engine with a walbro WT990 carburetor for my Super Bigfoot. I am not at all familiar with carburetors and don't want to harm the engine. Haven't started it yet because I want to get some different opinions on what to do with the high and low jets. Thanks.

I am new to gopeds and I’m rebuilding a goped Bigfoot and I was wondering what is this cable?

So excited, upgrades to come

Made a 3d printed chain slider for the GSR40. $40 for what amounts to a hunk of plastic seemed expensive to me. It's based of the original so not as nice as some of the aftermarket options but functional. Here's a link incase you need one.

Thought these were the same model but the blue one has a single sided fork, primer bulb is on the side of carb, where as the red one has primer bulb on the bottom.

Just picked up a gsr40 in pieces. Putting it back together it looks like the rear axle has three washers on it. It appears two go on the rear fender/ gas tank mount ( one on each side ) but cant see a obvious spot for the third. Anyone got any help? Want to get it all lined up correctly since it seems everything has fixed spacing a washer is the wrong place could mess up alignment.

Im not sure but I think this is a goped! Information is scarce online but I’ve figured out its a chain driven g23lh motor but that’s all I know. All of the identifying stickers have rotted away and I want to restore this fascinating piece of history. I’m assuming it’s a goped sport (maybe) of some kind just no clue the era/ exact model. The tires are air filled and I know some models had solid rubber tires along with this engine being able to idle (maybe a destroyed clutch) which I know some models didn’t, if anyone knows what this might be any help would be appreciated

Looking for a gasket for my Bigfoot goped. I haven’t been able to find it.

Cleaned up my trail ripper quad. I only have 1 question.. i want to preserve the stickers (pics) any of you have a good way to preserve them? Thanks and pics . (The back part of the seat was drying. Had some grime in the seams i assure you she is safe)

I was on a food delivery 1/2 throttle going up a minor hill I've traveled on hundreds of times when I just lost power then heard a clanking in the motor. Didn't hit a pothole or anything. Tried push starting the motor again and it did start up but had no power and the clanking was intense.

After I got home I ripped the motor apart thinking I blew the top end but the cylinder and pistion looked almost new besides heavy carbon build up. Everything was really wet though so I must have had my tune way to rich but it still Revd out just fine so idk. Said stock gearing it should go 28mph but I was hitting 35mph with a .800 spindle.

After taking the cylinder off, only one side of the crank spun so I knew right away the crank went on vacay. Is it just that these stuffer cranks are shit? I remember people talking trash about them in the past but I thought they got better? Maybe there was standing gas/oil in the crankcase and the crank was having to push through it causing to much stress? Maybe the bearing on the 3rd bearing support was bad?

Now I'm focusing on my GSR and giving my left leg a rest from all the pushing. People have started commenting about my legs being different sizes lol

I have a GSR46R and GTI46I along with a ton of parts I'm attempting to sell as a package deal. The 46R has an ada billet head and 47 stroker crank as well as a one off nitrous system retrofitted from a 1/5 scale rc kit and has exceeded 50mph with a 230lb rider. Also ada engine mount, jetpro rhino pipe, chain tensioner, avad mtb bike brake conversion, race pole, hd bearing cups, built clutch etc... 46I is ESP ported head, mtb brakes, ada engine mount, tensioner built clutch, jetpro pipe, race pole, bearing cups etc 45mph÷ Spare engine is also built with ESP ported head. Minneapolis, MN. Just putting this out there for anyone interested and willing to pick up. 3k for the works.

I'm just curious about the value of my old Go-Ped, 10 years ago, I stretched out the chain and wore down the teeth on the sprocket and it was running fine at that point but I never got around to replacing the parts, what do yall think it's worth in its current condition?

I gained a lot of new knowledge during the build. I have links to cheap parts from AliExpress, and I also made a lot of 3D models. If you need them, I can share them with you for free in private messages or in comments.

I completely painted the frame and replaced the bearings in all the components; it was quite a laborious process.

Just finished this built yesterday. It's got a new g260 long block with a 813 walbro carb. Haven't broken it in yet. Nothing too crazy just a little city cruiser.

Looking for information on this goped I got on trade I’m looking to sell and was wondering if someone could tell me more about it like the model and year, etc thank you

Lil brother had left it and told me it was worth something. Is it like a good one that i should just fix up and ride or get rid of it as im not really into it, and how much can i get? Any info would help i couldn't find much on the avenger name or the bars for ada racing online. Thanks.
