Very interesting things going on i've never come across before.
Was starting to wonder if previous owner had stroked the crank pin holes, moved them further out, similar to when i used a 70mm crank in place of a 64mm in my 250 although the rod eye still cleared.
I thought the 2X7 might've been a typo but ok its a 250 number i see.
Always things out there to trick us, & that's another one.

One owner before me (son selling it for his father who passed away). Only 2k miles on the motor. Never been apart. Sat since 1998 in a garage. Was never kicked over or looked after.

Bill Bune said they can machine the rod's big end to match the stock rod so I'm pulling it apart to have it rebuilt, again. LOL
