swapping older xv700 to 1988 xv1100

PostAuthor: Arjay » Wed Oct 02, 2019 8:44 pm

Hello all.

I see engine swap post of xv750 frame can use xv1100 engine. Older two pickup, so tci will work, minus pressure sensor. Maybe some issue with xv1100 bulging sides, fixed by footpeg swap or clutch side cover swap.

What about the xv700, is it same conditions for accepting older 1988 xv1100 engine?

The xv700 is 1985. Probably should work like swapping 1100 into 750 frame, true?

Externally they should work. As the 700 never has been available overhere, I don't know which ignition type it runs, but I suspect the earlier single-pickup ignition, so that should (aside from the bulkier sidecovers) be the only real issue here.

:yup:

the XV frames differed by Generation in suspension (which affected engine mounting also).
Gen-I was p/n [4X7-21110-00] --- however, they are the same for all models (750-920).

Generation-II is the same way. same frame for all models 700-1100 = [3CF-211110-00]
>>> https://www.mrcycles.com/oemparts/a/yam ... e509/frame

besides the electrical/ignition issues there is also slight mount/furniture differences between generations --- all years using basically the same engine (dimensionally)

Cheapness aside, if you use the ‘85 XV700, you also get the crappy starter system. Are you sure you wanna do that ?
