hope nobody else has to deal with this company.fusion motorsports has my motor cant find any cause for the piston failure.tells me i have to spend 250 to replace it after two and half weeks still nothing done the employees are to busy playing with thier own stuff to work on mine. meanwhile thier out racing myself at home not racing needing my motor back. i now know not to ever buy another motor from them again.i'll spend it on something more worth while. what a waste of $1000.00 could have baught ten chaep motors and be good for two summers.
