    Sundiro 50cc two stroke quad build (eton)

    haha it gets the job done! it is a cvt trans, basically the same motor as a moped. i didn't make the ports bigger, just made them smooth and removed the lips that are bad. i would loved to make tuned pipes but dont have a pc or the software to print out and cut into prices as templates for sheet...

    thanks! i got the new jets and the 90 main works best! its got so much power its awesome the tires just spin when you gun the throttle. I'm trying to get at least $600 for it but I'm hoping to get another project as well.

    I'd love to, but live in the suburbs, and noise is frowned upon haha. I'll try and take a video of something at least for you. I'm running 32:1 for break in and 40:1 after so there will be smoke in the video haha

    well all the engine work is done. its pretty big, good size for a kid, comfy for an adult just not for long periods of time. between all the work it now has a power band that is 2 or 3000 rpm higher. it is super responsive! but stock they aren't good for much besides putting around. here's the...

    hey guys, i did a lot of the mechanical work today. i fixed the piston, head, ported the exhaust, ported all the intake ports and made sure the ports would not catch the piston rings because it was just roughly put together. i took a bunch of pictures for yous: as you can see the new...

    i bought the big bore kit, the vinyl for the seat, the cdi, and pod filter today. woohoo, now all I need left is to figure out the jetting and get the pilot and main jets. the exhaust is going to have to be ported because its not round haha.
