Kimjon Posted February 10, 2019 Author Share Posted February 10, 2019 Okay, this project got put in the corner next to the kids keyboard, karaoke machine and the karate suit...(that's a joke, but close to the truth). But today the sun shined it's light on it: Then some heat resistant paint. Job pretty much done. I may wrap it...may not? I put a cheeky spray of engine start in the air filter and pulled it over...ting...ting...ting.... success! Huge compression and wild port timing should be a real screamer!!! 4 Quote Link to comment Share on other sites More sharing options...

Funny thing about this photo is that 3 weeks later my arm still hurt... 4 weeks later I got it x-rayed...yip - broken wrist!!! 2 Quote Link to comment Share on other sites More sharing options...

They look cool for sure just wondering if it's possible to design something that sucks in terms of exhaust timing (or other extreme get lucky and have something that rips)...

Kimjon Posted June 10, 2019 Author Share Posted June 10, 2019 Tadah!!!! Finished (well, 95%) my green/gold/black metallic goped. I haven't actually started it yet, as the missing 5% is the brakes and kill switch, which just needs a cable from a bike shop to finish...but not so safe without it. It's a sure sign of getting old when you're such a pussy you wont ride a wildly ported and untested motor without brakes. Meowwww...pussy...pussy... is all I can hear in my own sub consciousness. Meooooowwww...don't be a pussy! 1 Quote Link to comment Share on other sites More sharing options...
datlow Posted June 10, 2019 Share Posted June 10, 2019 It’ll be perfectly safe if you put it against a fence or post and do a stationary load test 3 Quote Link to comment Share on other sites More sharing options...
Kimjon Posted July 6, 2019 Author Share Posted July 6, 2019 Righto! Finally finished this thing. This is the first time I've heard it running ever: Then, I swapped out the exhaust for the expansion chamber: And it would be rude not to test it on the driveway. The phone sitting on the ground always gives terrible perspective...but it goes pretty fucking fast for 22.5cc. I've got a few quicker gopeds, but not by a lot. It would really benefit from a bigger carburetor, as its tapping out way to early and I know it's got way more potential in it. So that's the plan...find bigger carburetor...try again. Anyway, these things are never 100% finished, as there's always room for improvement in anything you make. But overall it's pretty sweet! I'm putting it down as a win. 6 Quote Link to comment Share on other sites More sharing options...
