Okay so it ended up being both the bottom and top end all at the same time :bang: I dont know how this is possible but it was the connecting rod that went and same with the piston
How do you mean, 'it ended up being'? If the con-rod went you shouldn't have been able to start it at all after freeing it up --- it wouldn't move the piston to create a compression stroke or turn the crank from the combustion fire.
Bummer, anyway! Sorry to hear it! From your list of bikes I see that was your newest one --- like me, you ride old iron.
I was fond enough of my '77 IT400 that blew everything but the transmission when the con-rod broke that I bought a '78 with no compression and a wicked piston slap. I thought it was just a bore and fresh top end, but turned out to need a whole replacement cylinder as a previous overbore was done out of square somehow (amature machinist, or something). Between the bike, bore (used cylinder) and some miscellaneous parts I've already got about US$600 into it, and it's an old bike. Something else could go next.
But the ITs are really cool! I've got an old KDX as well, and it is more advanced technology wise, but those old Yamahas have a different kind of cool. They were the first REAL Japanese competition enduro bike, and ruled the roost in their time. I can't seem to kick the habit.
