Is it possible to put the powervalve from a rotax 122 engine into a rotax 123 engine?

Just curious as I have only found 1 powervalve for sale so far and thats for the 122 engine and I have a 1992 AF1 123 rotax based bike.

Dunno what the futura's have as standard, but if the one you've seen is an electronic one make sure you have the other bits for it, Control box, solinoid etc. Don't think an electronic one could be fitted to my 89 AF1 as i have no provission in the loom for the control box and solinoid.

Keith will know :rolleyes: :D

yea mines same model and got an electronic one, so one should fit in, i just wasnt sure if there any sizing or technical differences between the 123 and the later 122 blade
