I'm guessing youve got a 41.? stroke,,the Stage6 seems like its a Mina 39mm stroke casting...  |

I recently realized the stock small end bearing was not going to be wide enough for a 70cc kit. I found a wider bearing in my new parts that fit the S6 piston perfect, but was a bit wide for the Athena piston, so I opened up the Athena piston with a file so the wider bearing would also fit. Once again I started checking durations for the two kits and wound up with the Athena cylinder and Athena piston set to EX 193 and xfers 132. Using the S6 head with a 1.3mm head gasket (I gotta fab one up) should get my squish in the range of 1mm as the Athena instructions specifies. This is my first aluminum kit install and 1mm sounds kind of wide to me. Is the squish normally wider on the aluminum kit?
I also still need to document the Yasuni R pipe so 190mech can tell us where its power band will likely be.

Ya I'm interested in that Yasuni R pipe too! I'm wondering if it wouldn't make a great pipe for the Hoca 90cc stuff as the C16 seems to have the power band a tad too high...

Niz,Ya oughta try that 40mm spacer in the headpipe we discussed to get the lengths right on the C16 to 103cc before looking for another pipe... |

Was more just thinking out loud about the R, but now more focusing on the 50mm LC MHR Big Bore(s) sitting on my workbench! |

Sorry for getting sidetracked Oldgeek!
Seems like maybe the extra stroke on your crank could be a blessing in disguise? Seems like I'm usually running into the opposite problem with way too much squish clearance...

I think this is a better problem to have, just make a couple spacers and its fixed. The more I look at this Piaggio motor, the more I like it, no wonder they are so popular mostly everywhere but here. |

Going to premix. Is the pump easy to delete on these?

It's belt driven and super easy to remove.

I thought I read somewhere that some type of spacer is needed in place of the sprocket? Maybe not, cant remember. |

190mech I finally got the pipe dimensions! 
|

With the head torqued squish is a little tight at .6 I am hoping the copper spray I plan to use will add a little more clearance and get me to at least .8 or .85 with the squish.
