well....after doing a leakdown check on my motor, it became painfully apparent that despite all my efforts to address the oil burning rear cylinder, something had taken big shit....

This is an original two owner 79 Sporty with just 8k on the clock...I think the last owner truly F'd this bike up trying to get an ancient Lectron carb to work on it. So anyway, I went to the liqour store to get started on the rebuild...

Heres a few quick pics of the tear-down....

here is a pick of the suspect piston....looks like a limp dick....the rings looked almost "polished"...they were pretty worn...and the piston had a little more than the usual scuffing...time to start a new life as an ashtray....

I think at sometime, all sportys top end's get to hangout on a workbench and watch us run around trying to find shit we lost or misplaced! :)
