Greetings my man! We're in the same boat. I'm trying to build one for the missus, her mini 1000 auto trike is too slow so we figured a 1300 Xflow might do the trick.Trouble is we baught seperate parts rather than get a complete runner & scrap it, no spacer between the crank shaft/starter ring gear, the vacum pipe on the R/H side of the box is meant to fit somewhere on the inlet manifold or carb but we don't have a spare connection up there, so lordy knows where, the starter motor wont fit 'cos it hits the bellhousing, & if that i'nt bad enough I've just dropped my pickled egg. At least yours has got paint on! If you pass Somerset we can make a fine cup of tea & might even find a biscuit or two. Good luck, Mike.
