Curiosity on my part but at what hour did you do the first top end. Also is there a reason you didn't clean the power valve?

[@ryanboening]

@@jdm1200 First top end was at 55 hours, the piston looked pretty decent but the rings were really starting to wear. I didn’t clean the power valve because I didn’t think it needed to be cleaned. It wasn’t too bad at around 110 hours when I rebuilt again and cleaned the power valve.

@@ryanboening I'm an old big vet rider but I sure love my 125. I think I enjoy it more than my 300.

@@jdm1200 they’re a blast for sure!

How are you using a longer spark plug? Won’t it hit the top of the piston?

[@ryanboening]

That’s a good question, if the plug is a lot longer yes, but this plug is just a bit longer. Assuming it mostly helps to be more in the middle of the compressed mixture for a faster and better spread of combustion.

threads are the same height, so it wont go further in cylinder head

[@ryanboening]

@@AtMortenJ yes, but it will go further into the cylinder, just a tad since the end part is a little longer

What’s the brand of TPS tools, please? Where did you get it from?

This is the one I am using in the video, you can also purchase just pig tails so you can use a multimeter. But it’s a little tedious using pigtails

[@crispy4942]

where did you get the user manual from
