yea i would def. change the back sprocket too... unless you're wanting to stunt it as well i would maybe go -1/+3 if you still want that but -1/+2 will be plenty of acceleration. but ur bike, ur choice of course.


also i have a Q related to this topic
when i bought my bike the guy said he wasnt sure if the sprockets were -1/+2 or -1/+3
so i can just count the teeth on my back sprocket and if its 49 i have +3 and if its 48 i have +2, correct?

 

correct it came stock with 46 teeth

 

Yea, I think I may end up putting the stock rear sprocket that came with it back on and just order a new front. I'm gonna go out and count the teeth on that rear sprocket thats on there now and figure out how big it really is. I have a feeling its not really "8 teeth bigger than sotck" like he said, now that I've been looking at them online.

 

Great write up. Succint and learnable. Sorry, i didn't mean to steal the thread.
Having said that...and i just want a little more off the line would -1/+1 suffice? I'm not concerned about top speed. However, i "may" go to the track a couple of times, but that will be it. Or am i wasting money??

 

HockeyFan, a -1/+1 would be enough for what you are looking for. I have the -1 in the front only and 46 in the rear, and I can bring my front end up with a twist of the wrist. If you are not concerned with your top end speed, you will be happy with that set up. Besides, who goes over 150 mph anyways? Unless your on a track, driving that fast on a highway is very unsafe.

Heres a link on ebay that sells them. I have an RK kit like this also, and you will get different opinions from people on which chain is the best. I have had my RK for over a year now, with no adjustments and it rides great.

 

Thanks Stephens. How do you find 2nd gear...is it still zippy enough for you? And how much the speedo off? It shouldn't be too bad.

They didn't have an 05' version for an F4i, but they are local and I'm sure they are a phone call away.

 

How do I find it or how doI like it? 2nd gear is just a click of the shifter bro.Performance wise itsstill very fast. But my riding style is a bit different than yours probably. I ride around town in 1st gear and don't use my second very much unless I am shifting up to go on the highway, sometimes I will use 2nd gear around town. 2nd gear is still quick and fast. I have a Two Bros. Racing pipe, so I like to roar around town making noise, so riding around in 1st will do that, and I ride the powerband.

As for the speedometer being off, I installed a Speedohealer to correct the speedometer. But the speedometer is pretty close to accurate in 6th gear on the highway only off 2-3 mph before I installed the speedohealer. In town in 1st gear, my speedo would read 35 but I was actually doing like 23-24 mph. I had a friend who has an 01 F4i all stock, so we measured the speed off of his bike. The speedohealer was about 100 bucks and worth the money, cuz now my odometer won't rack up extra miles and stays true. Once you install in, go to www.speedohealer.com and input your info the number of teeth on your sprockets and other infor asked, and then you can configure the speedohealer. Good luck.

 

Sorry for the off track question but, how come I can't find any 48t sprockets on ebay ???

i dont have to figure out how fast im actually going and calculate percent error and all that?
