Good will makes it better for both parties.

A guy bought an old dirt bike off me, it was when premixing 2 Stroke gas was no longer needed because of oil injectors. But I never could verify how much oil was being injected because the manual was vague onsettings the injector.

He saved up $150, hitch-hiked to my place and rode it home. A few days later he called to ask troubleshooting questions, because it died and wouldn't restart, and he had no mechanical knowledge.

I went through the list:

• is run switch on OK
• does it have gas OK
• is the petcock open OK
• check aifilter for dirt OK
• does it spark OK

Hmm

• when you kick it over how does the kickstarter feel, can you feel compression ... NO spins easy

OK, rings could be shot, or piston is blown.

Dude was crestfallen. Because he was low on cash and had no experience doing work himself.

I said there's a parts place between my house and yours, I'll grab some parts.

We spent the next two hours disassembling the head and cylinder. Piston had a hole blown in it. Probably too lean a fuel mixture.

Swapped for new piston and rings.

We still could not make sense of the manuals oil injector setting, the image made no sense on how to set the valve.

Started right away. I said the rings have to wear in, so take it easy for the first while. He rode it out like a bat out of hell, up and down a field, with me cringing. Then Pop! Blew the piston again.

Sigh. I was disappointed, but didn't know if it was his riding style or a faulty injector. But I know I did the right thing trying to help him out.
