I do understand i as well as other folk have had vehicles like this.
I had a cb125t that was nothing but work. Rebuilt the motor,wheelbearings, clutch electricals. But i stuck it. Partly cos i wasnt letting it win and partly cos i was skint. I had to make it work or walk.
I had a rd350 too. Never worried about a drilled sump plug? I do now. Thankfully someone stole it.
So i do know your pain and i still think its a cop out. Even worse you know no more now than you started. This bike could have taught you so much.
