2 STROKE TPI POWER VALVE TUNING

[@stormriders343]

I did it to. Bike feeling super usable also powerful. But weird noise coming from silencer at low rpms puh puh puh :)

Mine does the same untill it's warmed up. Also if you have a spark arrestor check the cone. And clean it. I took the cone out and put it in a s small bowl of gasoline and used a little wire brush.

@@chainslapmoto I bought a used bike.Spark plug was almost seemed to fall and cylinder head was filled with oil:) I will check it more

[@chainslapmoto]

@@stormriders343 ah the fun of used bikes!! The only bikes I ever bought new are our kids 140s. You usually get a lot more when you buy used. But you can find gremlins too. Good luck!!

I think 2.5 turns in from flush is how they come from the factory. If it has the stock spring.

[@chainslapmoto]

@@316madness sounds about right. That's about an 1/8 inch from flush with the case.

It definitely is werth adjusting mine standard was really flat, unresponsive and boring!!! If i wanted my 2 strokes that way i would buy a 4 stroke.
