OK, general thought... NO.. Asside from the 650 being a twin, & the 750 a cripple, the games to be played trying to fit/jet arent worth the effort. while ( in my humble opinion ) The XS 650 is the best English twin never built, It's head 's ability to flow is probly its biggest flaw, & doesn't gain much w/ carb work. my 2 cents G
