New Cylinder and Piston NEED HELP!

[Primariz]

hello to all!

prepare your self for MY horrible dumb mistake.

So here we go! a few weeks ago I order a new piston and cylinder since the original ones I had were all kinds of f***** up. I received the new piston & cylinder and immediately installed them without reading anything or having any experience what-so-ever. once I installed it and got the scooter running I was amazed by the new sound and the performance of the engine even though I never went full throttle since I was trying to be "careful". Problems started happening as the days passed by; the scooter was loosing more power, engine would sound different, clicking,etc. At last the engine finally stopped today and realize that the piston and the cylinder seized up and some how managed to separate them apart. went online and realize all the mistakes that I made. lubricating the piston, making sure which rings goes where, hoaning the cylinder, and installing the right gaskets.

So now what I am asking is if anybody can give me a detailed step-by-step on "how to install a new cylinder and piston" from you fine experts.

here is the cylinder and piston I bought from ebay: http://www.ebay.com/itm/380592194335?ss ... 1439.l2649


if you want pictures to see what I did i'll be more then happy to post them.

thanks for your time!

Was that a spree cylinder kit from eBay?

You need to put some oil in the fuel for break in as well as what the oil pump puts in.

sorry for the late reply! yes, I did buy the spree cylinder kit with the piston and the cylinder for 85 bucks. i feel like the metal the piston is made from seems cheap. but I have no experience with any of this so I'm not exactly sure. Also the rings with the kit seem the same(grey with a silver on the outside). one is just thinner then the other one.

I have one of those kits and the piston looked fine. I have a taz piston as well, I'll compare them. The tax stock piston will be better for sure but that one that comes with the kit looked usable. I haven't installed that kit but I may use it with the spree I have to go pick up soon.

Have you installed that kit yet? The base gasket in those kits need be cut to match the cylinder and block or it will not run properly.

Grey gasket is from that kit, the green gasket is OEM replacement from honda

[patthesoundguy]

The rings looked fine in the kit. I have and aero 80 kit showing up tomorrow from the same seller, just to have it on hand for when I finally wear out my aero 80 top end.
