400 ex engines

[KILLER EX]

will the new one with reverse fit the old quad with out reverse?

[TC426EX]

yes

[44oEX]

it will if you change the complete motor. But there is no way to put the reverse in the old motor.

[KILLER EX]

thanks

Yes it should fit but you might need to do some mods for the revers handle if it is like the 300ex. just bolts and stuff.
