looky here its pretty much identical to the GP one
take of the engine cover and its on the back right corner of the engine
if you clean it or fit a new one i reccomend fitting the moddified swirl gasket
part no. 71751469 is the swirl gasket in centre of picture, 12 quid (ish)
you'll also need two 46773082 (£1.80) for either side of the swirl gasket
