A '08 Suzuki B-King (gen 2 Hayabusa engine) with some exhaust/air/fuel mods and dyno tuned.
I once had a Suzuki GS1000E with a Kerker 4 into 1, and 2 different GS1100Es with Yoshimura 4 into 1 exhausts. I guess I was getting around 120 HP with the jetted 1100E. Fastest bikes I ever owned.
Bike I have now is just 75 HP but powerful enough for this 59 year old.
i get my money's worth as far as the performance of the zx-14 is concerned..i usually do a 2000 mi. oci..kinda conservative..i'm considering m1 vtwin 20w-50,rotella t 15w-40 or 5w-40 t6..also amsoil 20w-50..motul is good but premium priced.this bike is known to run on the warm side,hot in traffic..socal's climate and the aforementioned is why 20w-50 might be the choice.
2000 mi oci is a good starting place, unless its a common practice on 14'S to run 50 wt, id be leary... whats you book say ? I do track days and mixed street cruising/ back road scratching and 1,200mi is when i start thinking about the oil if ive been very hard on it. it all depends on the abuse ive put it through durring the oci, for a inline four i prefer
mobil 1 4t
all 40 wt's andi know there's plenty of other good ones, i just have experience with these.
if its been a mostly street, some back road scratching oci.. 2000-2500 is the most i like to go (but some of my backroad antics are somewhat compareable to trackdays.. so the normal max
i HAVE blown a inline four on honda gn4 40wt.. im a pretty firm believer in higher quality oil now..
i agree 40wt.syn.2000 mi oci for my application..20w-50 although ok to use 32-104* plus according to manual might actually produce more heat due to more viscous fluid..besides i usually do not ride in 100* temps,but i do love the desert..
