The back hard numbers section of Motor Cyclist staes that the Honda F4i will run a quarter at 10.71@126.7 the R6 will run a 11.01@125.3 So its clear that despite the Hp difference the F4i will deffinetly spank the R6!!!! The rider will come into play but this was tested by the same rider over an average of 8 runs per bike. Beside the F4i is a better bike anyways! Thanks

 

when u drop one tooth in the front do you keep the stock chain too or do you have to buy a new 520 chain or something like that. I think i might just end up dropping one tooth in the front and keeping the rear stock so i'm just curious about the chain or anything else that i might have to buy. thanks for any help

 

not sure about the chain, it should work with -1 in the front, mine has aftermarket renthal sprockets and i'm not sure what kind of chain, i know it's not stock....sorry i couldn't be more help.

 

if i went -1, +2 would my bike be too "buzzy" or anything like that if i'm just cruising around town or at highway speeds. I'm not worried about top end at all i just want my bike to be snappy. i want to go with the -1, +2 just because i think that's what will give me the most acceleration and that's what i want so i just want to hear what some of you have to say. Thanks for any help

 

with just -1 in front, mine is not buzzy, but you can damn sure tell that it has been dropped a tooth, with -1 +2, it will be really snappy and you will probably have a hard time keeping the front wheel on the ground. with that set up, you will probably run about 2-3K RPM's higher when you going downt the highway. if you want to do high speed wheelies or even low speed wheelies, then the -1+2 will be perfect, but if your just going for acceleration, -1 in front should do you just fine. i have no problems doing 3rd gear stand ups on the highway with just -1 front. but it is all personal preference.....just my .02

 

if i do go with the -1,+2 will i lose THAT much top end. i hear about 2-3 mph for every tooth you go up in the rear and that doesn't seem like too big of a deal. If i were to say keep up with someone at higher speeds would the +2 drastically effect my top end. I know that it will effect it a good amount but would my top speed be more around 130 or like 145 with the +2? thanks in advanced

 

Do yourself a favor and just go -1 first on the counter sprocket. Ride it for a couple of weeks and see how ya like it. I promise you will notice a difference. If it still doesn't accelerate fast enough for you then go +2 on the rear. Sprockets are relatively cheap ($15-$40) so it's a mod that makes a BIG difference but much more cost effective than HP mods. As has already been pointed out, if your chain already has a lot of miles on it you might think about replacing it also -- sprockets/chains do better as a set.

 

i agree with chainstretcher, just go -1 up front and see how you like it and just go from there, if you don't like it, then just put the +2 sprocket on the rear and your done....

 

alright that's prolly what i'll end up doin. Thanks alot for all the help and patience. Thanks again for all the info.

 

anytime....
