I found a 178cc one online, however from reading this forum most people are only talking about a 140cc one?

Largest Cc’s you can go on the Z125

Guys I’m going to rebuild my z and I already have a 143cc kit with larger valve head and mid size cam. I have the larger 26mm thrott body and a pvc. I was thinking of going to the 173cc and add the striker crank to make it I think194cc. Any thoughts or issues you can see? I want to go as...

If you bore the case an add a stormer you can make it 194cc, I just changed mine from a 177 to 194 today

did you have to open the case up anymore offer the 177cc cylinder jug? I had my case bored for the 165cc and have the stroker crank to make it 177cc but would love to go to the 194cc set up f I don’t have to bore the case any larger.

I did a little

Did you pull it all apart or do it in the bike with rags ? Wishing I opened it up a bit more.

I did it with rags this time

Yeah that’s what I was thinking I might try. I’m sure I don’t have to go that much more to make it fit. Damn I wish I had gone all the way in the beginning. The problem was I couldn’t get the parts at the time I wanted them.

So in your opinion there’s a big difference between the 177 and 194cc up size?

There is in the torque area, both if i wot in first will wheelie not trying, the 194 i can shift while its in the air and as the front comes down as so as it bounces it will pick the tire back up, the bike been [email protected] mph with the 177cc, so hopefully the 194 can out do that

Rey cool. Any idea how much bigger the cylinder skirt might be vs the 177? won how much more I’d need to open the block up.

 

[Ls13ater]

Its not much, mine was 2 small areas, i did my case bore myself, i should have opened it up to a 194 the first time

 

[Somefun]

Yeah me too.
