wow, thanks. i always thought that it would blow up if i rode the engine hard when breaking it in, but i had a 2stroke

Warning:
This is a very controversial topic !!


The Short Answer: Run it Hard !


yeah you willl get different opinions on this very many different one... i dont personally think riding it is hard i think its not good at all for your motor but its your choice
