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.

Same engine is it not?..ALSO fits in the MZ varient too..

My '03 MZ Baghira 660 had a carburettor not fuel injection, I also think production finished in '05, so never had quite the same engine spec as the Pegaso or XT, hopefully it will be pretty much the same, good luck.

Al.

thanks Xtal.....It's going to be a laugh finding out

There�s a huge difference between the XTZ660 engine(3YF) and the XT660Z engine(11D): first is 5-valve and last is 4-valve. The 3YF engine is used in the MZ bikes, so can not be used in the 11D Tenere(I think!?).

I assumed the op had done some research into the engine before buying it.

Without year of manufacture/engine number etc its all guesswork.

Im looking forward to the progress and pictures.
