engine is completely rebuilt, using custom-made piston, exhaust, connecting rod, crankshaft .... and this set gives 48 hp I testing on dyno

Nice skin, A stock YZ250 has 47hp so i doubt you have 60hp unless you are riding one of mitch paytons bikes and the amount of money to keep it running would cost too much. After a pipe you can get almost 50hp.

a 2010 450 has about 55hp- 60 hp...and i know that for a fact...and you all know there is a big diffrence between a tuned 125 and a stock 450

If your 144 produced 48hp you'd literally have the most powerfull 144cc 2 stroke engine in the world.
You are telling me a small cylinder bore plus a new piston, rod, and crank plus an exhaust has given you an additional 60% power?
I'd like to see a dyno sheet of your actual bike showing that result.
