What piston and what motor do I need/have?¿

[SHOmolka]

So I’m rather new to complete motor work I just know the basics. Two things I’m trying to figure out. First is exactly what type of motor I have. I ordered a “100cc” off Amazon and the motors great but it’s clearly some type of 66/80 after measuring the bore and second I have a reed valve I want to install but need to figure out which piston to purchase. I was about to purchase one but I noticed someone in reviews saying they got the wrong one as it was advertised as a high hole but instead got a low hole. What the hell does that mean? Haha. Any help would be greatly appreciated! Glad to join the community

Before going for any more power I suggest you get some slack out of that chain. It is wayyy too loose

I think we need to talk about fenders, too

And lets not forget some sort of air filter to prevent grit from scoring and destroying the cylinder.

Agreed. He removed the less dangerous (but still quite dangerous) rear fender.

He truly needs to read this since he still has that front fender on his...Major maiming or death resulting with those fenders.

Safety - Beware the fenders!!!

Don't take the warning lightly!!!!!! My son in law is in the hospital in critical condition cause of the fender getting into the tire and rolling around till it locked the front wheel and threw him over the bars. Of course he wasn't wearing a helmet:helmet: This just happened Wednesday. Here's...

That is one thing I didn't listen to when I first started building bikes. I was foolish not to, I got out lucky with only having to rebuild my bike and not ending up in the ECU. When I rebuilt my bike I made sure the fenders would stay attached (now that I think about it it's still dumb and those are gonna go when I swap the forks).

Ill admit I was warned...

Just to start off with, fenders look sick, but they come at a price. I love the look of fenders on a bike, and I would love to keep them, but I should have taken the 5 or 10 minutes to reinforce mine. My bike is an older Huffy Newport. It's an amazing frame, and it has fenders. I was headed...
