Guys need some advise please, 05 650 Rincon with off frame build.I have a 680 crank,680 cyl,fresh port and poilish head(650) new valves,ect. My question is will the 680 camshaft(new oem) work and perform on my 650 head? It looks like the lobes are bigger due to the fuel injection but wanted to know if I can confirm a definite answer on any of the forums or google? No info on lift or duration of the 650 or the 680.Also if this wont work should I go to a webcam and send back the new 689 cam to Honda? Thanks guys :)
