Re: what did you do to your motorized bicycle today?
Today I called Duane... Yes that Duane and that call. Tanglebones down. Motor dead.
My RT head came in from Dax a few days ago, which is very nicely made, far higher quality than expected. I tore down my top end to install said head, and discovered horror and carnage. Left side wrist pin retaining clip lost it's ears. The cylinder and piston found them.
From the looks of things, the fragments made their way into the exchange ports, took a stroll through the case to the right side transfer port and left the scene of the tragedy via the exhaust.
A few weeks ago, I heard a nasty metallic noise from the engine, coupled with a noticeable loss of power. I discovered a broken exhaust header weld. After changing pipes, I was back to riding, although a bit gutless, for about a hundred miles. Looking at the grooves in my top end, I can't believe it ran at all.
