I haven't updated in a while because other machines and priorities have taken... priority.
To recap: the piston was slapping, probably because of my exuberance with the honing stones. It got worse with the new piston.
So I was going to drive it until it imploded, but instead I left it parked.. .
Then a new Pinasco 177 kit showed up on my door! A gift from my good buddy Chris! I think he was tired of me moping about and not wanting to ride B62. Super kind of him - thanks man!
I took some time yesterday and today to pull the engine, inspect the top end closely, install the new kit, and go for a spin up the street!
I'm pleased to say the rattle seems gone. I'm gonna go nice and easy on this new cylinder and piston, but not too easy
I took my time during disassembly to see if I could find the "smoking gun" to the rattle but no such luck. I'm gonna go with I oblonged the cylinder or something whacked like that.
During reassembly, I also took my time, using new greased up gaskets, and of course doing a leak down test.
Tomorrow I'll take it around the neighborhood. I'm pretty excited to have it back on the road.
Oh, I almost forgot, I bought a side stand like SoCalGuys. I flippin love it!
Time to pull the engine - dangit, where is the coffee and pastries?
An aside, I organized my carb box of parts into this - super helpful!
A few marks, but no definitive thing to point to the horrendous noise...
Screw it - let's put on the new kit
Checking new ring gap - looks good
Spooged up base gasket with RTV. Time to install the piston, then slide on the cylinder...
Head greased lightly and torqued down.
Done for the day....
