GY6 49cc ?

[2strokd]

Has anyone tried a Wiseco piston in a GY649cc engine? Do they make one for it?
I am about to rebuild one so im trying to get my ducks lined up.
The owner has a $100 certificate through Wiseco so i thought ide ask?

Any other suggestions or input is very welcome and would be appreciated. This is my first GY6 build :devil:


Thanks :cheers:

haven't tried that yet.

wiseco web site lists prox racing for 49cc pistons.

look under Kymco 50cc

currently out of stock for std piston

first one in stock is a .25mm oversize for $58.68

Wiseco Part#: 01.1010.025
Product Type: Single Pistons
Description: Pist Dio / New Tact 50 / Kymco -GW0/GW2-

think it is a forged piston, made in japan.

I do not think it includes wrist pin or rings.

I would suggest a 72cc cylinder kit (47mm piston) by NCY from enviromoto

Wiseco is in the US I used them when I had motorcross bikes as they machine the piston out of bilet instead of cast and then forge it twice . I thought about getting a piston for a Honda XR 80 to use in a 50mm BBK since my POS TaoTao had the piston crack twice in a short time and I had just over 30 two wheelers in my lifetime and never once had a piston do that .

If they do not have what you need they have a Japanese company they refer you to on their website.

They will make custom pistons in bulk instead just one , and maybe we could pool together and everyone have one . I really want a forged 2T piston and crank so I can have a screaming scooter and not blow it up

The GY6 is an old Honda design so look up Honda scooters there

I skipped over the important part in my post above

Why are you rebuilding ?

What kind of scoot ?

if it is a high dollar brand, then I would go with known high quality parts

if it is a run of the mill chino then I would use generic ebay parts

I see no reason to use a high $ piston when all the other engine parts are average.

for me it costs as much to have a scoot cylinder over bored by the local machine shop as to buy a new cylinder kit that includes a new piston.

so. how about a little more info ?

China scoot, stock. Ran good for 2 years. Owner has a certificate through Wiseco for $100
