Triumph Bonneville 904 roll ons with CB1100

[buck80mph_imp]

I own both a loaded down with luggage CB1100 and a loaded down with luggage Bonnie with 904cc big bore with CR 35 carbs. We did roll ons onlysince I have not had the 6500 rpm rev limiter fixed yet. 75 m.p.h. roll on the Bonnie pulls a bike length for a few seconds then here comes the CB passing and pulling away, 60 ,50, & 40 m.p.h. roll ons the CB slowly pulls away.? The Bonnie had its luggage bags fullnandvthe CB 11 had empty H/B 42L side bags and 36L Coocase trunk mostly empty.

I'll say what the drag racers would say. "It must have been the rider!"
I was thinking that the last time a "Bonnie" won a drag was way back in 1966 when the Triumphs used to pick on the Honda 305 Superhawks and Scramblers...
