I bought a Minarelli V1 NOS kit on eBay for $70 from handybikes and everything went fine but when I was checking things out last night I realized the piston is too big for the cylinder...With the rings compressed fully (and even when off) the piston is slightly too large to fit inside the cylinder.I'm emailing them right now in hopes of a quick response so that I can work things out.
Shit.
get some one who knows what they r doing to bore your cylinder out
That's a thought. There is a shop close to me but I don't trust them with anything really...
I emailed BJ at HB and I'm hoping I can work something out because it doesn't make sense that this doesn't fit.
Just hone it a bunch. It's not that hard. Just do it right. A blessing in disguise?
Handybikes is honest, they will make things right. The piston should easily fit in the cylinder without the rings. Sounds like mismatched parts. Peace. Jerry.
and yes, it is that hard to hone it CORRECTLY. unless you have calipers, micrometers, and a good rod hone.
Or just some liquid abrasive. Just put some between the two parts and rub them together. Thats what we do with trumpet pistons, and they have smaller tolerances than engines.
But that wouldn't work here cause it would need to fit inside. Get a new one.
