Im lookin to get a JP Fx 12t-03 and had a couple questions. I read some people are having problems with the red putty, but it seemed to be when people put after run oil in, i assume to get the engine dry you just disconnect the fuel line and try and start it up normally untill it wont fire anymore? is this right or wrong? I know this engine hasent been out for that long but does anybody know the longevity of the motor? i dont want to buy a new 400 dollar motor every 4 months. and last but not least whats the differenece between the modified motor and full option motor?
