Tecate Motor Swap

[bucko]

Will the 86 tecate motor be a direct swap into a first gen trike?

And what years of the KX250 would be a direct match?

[HuffieVA]

the 86 is NOT a direct swap, 83/84 KX250's are basically the same motor with different gearing and cylinder porting.
There is a great list of what fits what here:
