I think I may have solved my trashed engine / 3rd gear problem having taken the plunge and bought an Aprilia Factory (means nothing I’m sure) Pegaso 660 engine, with 5000 miles on it. Has anyone changed (chanced their luck) by fitting this engine (Yamaha unit) in to the Tenere?. I know, in theory, they’re the same unit , although the Aprilia one is black and has a logo’d clutch cover, but it should bolt straight in...please say yes.

I’m looking for any tips. My 1st guess might be the sensor cables the Aprilia loom uses, couplings, might be different in which case I’ll swap my Tenere ones out as far as I can. In one Aprilia review I read Aprilia have “breathed” on the engine to give a different power delivery, although vital stats still compare at 48 ish BHP and similar torque.

I'll post pictures in a few weeks when the lump arrives.
