hi all just wondering what everyone else gets out there bike i have a 1991 cbr600fm i only get 130mph 6th gear at 10000rpm and then it wont rev past that have been told the bike should be good for about 145-155mph but just cant get there have replaced near everything new iridium plugs new k&n panel filter new full s+s exhaust new chain and sprokets 15 teeth front sproket 43 rear and d.i.d chain cant think of much else to do apart from getting carbs rejetted so what do you all get and how you getting there cheers [8D]










live fast ride faster

 

i've gotten to 135...could have went faster but this is when my front wheel bearing went bad...scary **** at that speed....wobble wobble shake it shake it, anyway...seems my bike gets to that speed only when it wants to...sometimes it'll stop at 115-120 downhill and other times will go 135up hill and keep pulling...who knows...damn carb'd bikes

 

How much do you weigh? I can get 140-145 consistently. My carbs are jetted (Stage 1 only), got a V&H pipe, K&N...nothing done to the ignition. Chain and Sprockets are stock. I have seen claims as high as 160 on here...claims though. But 130 is a little on the low side I think.

 

i have to agree with ed on that 1...130 is a little on the slow side..i also get 140-145 consistently and have hit 150 a time or 2....you might want to have your bike looked at unless your a big guy ,because that could play a role

 

heh i'm only 150

 

sounds like its time for a new1000RR!!

 

hmm yes if a 92 katana 600 will do 120 just before red i thinkk the cbr should easily do 140

 

Yeah well I'm sure they could hit any speed so long as the speedo is inaccurate enough. With -1/+2 sprockets I could get an *indicated* 135 out of it. at about 125 I think my handheld GPS said I was only doing about 110. And before you ask I wasn't looking at my GPS at the time, it records the fastest speed.

Anyway, while I can't really criticize, what exactly is the point to get going over 140? I mean, in reality there isn't too much of a need to go half that fast. Who cares if it can go 160 or 180? If anybody is dumb enough to care just lie to them, because invariably you'll end up dead if you keep trying to get closer and closer to 200.

If you really think you need more power then you have to do some engine work. Cams, heads, that kind of stuff. And its just plain easier to get a different bike.

 

Keep in mind that elevation plays a role too. On ANY naturally aspirated motor, the higher you are, the less air the motor can pull in per revolution. All else being equal, your bike will always go faster at sea level than it will in the mountains. [8D]

 

cheers everyone managed 140 on way home from work today woohoo but going to look at a cbr600rr 2006 model on sunday so might have a new bike just shortly and i am quite a big guy cheers everyone
