Re-Phased XS 650 Engine. Bored to 707CC, Ported and Polished head, Custom intakes, Port Matched Carbs and Intakes, Dual Lectron Flatslide carbs 34MM, Custom Pamcopete Ignition (all electric baby!!!) 277 Degrees of Re-Phase, all done by myself. Just got it running in this video, needs tuning and timing, a bit rich still, but seems to run fine otherwise.
XS650 Engine, rephased by Hugh’s HandBuilt in Asheville NC. 277 Degree Rephase, stock bore, stock head, Mikuni VM 34MM Roundslide Carbs, Stock Headpipes, Pamcopete Ignition. This is a Kick Only engine, we deleted the starter and all the related shafts and gears.
Still needs to be broken in, fully tuned, camchain re-tensioned, head re-torqued and such, but this is a great running engine. The ticking you head is the valves, I run them very loose while breaking in an engine, at .006-.007″ so that I can guarantee everything is getting oiled properly before final tuning and install.
Notice that this thing is SUPER loose on my test stand (only 1 bolt holding it tight), but idles smoother than any stock XS650 engine you will find.
