I'm lookin to find out how many teeth i can fit on my rear sprocket if i am using the stock front sprocket and an e.k. gold chain that is used on the stock setup. I just want to replace the rear sprocket so the front end comes up a lil easier. thanks.:YEAH

 

you'll need to change chains regardless.. even if you go 1 down 2 up, u still need to change chain.. That's my suggested starting point.. just tnough to hit top speed, good enough accel.. have fun!

 

when changing spockets ALWAYS replace your stock chain

 

I have a 50Tooth (sprocket specialist) rear brand new and connecting links for a 525 chain. Pm if you're interested.

 

+2 without changing chain i dunno if you have to go -1 in front to get that or not. thats the gearing i have(-1+2) and front end comes up alot easier than stock.

 

stop being a puss wagon and learn to wheelie stock gears, its not your bike that cant get it up, its you .

^^ is ture i learned on stock gears, but do understand his point you have to dump it on f4i. if your chain is in good condition and you don't have to change then why do it?

 

Learning the stock gears is a good starting point because later on, if you want to go bigger, then you will have a better idea of throttle control even as it will be much twitchier.

As for changing sprockets...if you still are set on changing sprockets then there are a few things to take into consideration:

Streetability--If you still want to take your bike on the street, be able to keep up with the flow of traffic, and not burn up your gas or burn out your motor then I would stick to a mild gearing.

Controllability--The more you gear your bike, the twitchier your throttle will become. You're giving up high end horsepower for low end torque. If you're having trouble controlling the throttle with stock gearing then you will be disappointed in how much more difficult it will become to control your wheelies with bigger gears.

If you have your heart set on changing gears then do make sure you change both front and back gears at the same time as well as purchase a new chain to accompany your gears. Unless you want to go with a longer 130-link chain, a 120-link chain will limit you to -1/+5 at the absolute most and that may even be a stretch.

Finally, if you are going to invest in a new chain and sprocket then go with a 530 pitch--you might as well get the strongest setup where as a 520 pitch chain is more apt to break.

 

thanks for all the replies...I'm fine with getting it up in 1st and im doing wheelies in 2nd but it takes a good pull to get it up without using the clutch. I just want to make it easier for me to get it up in 2nd. Will down one in the front and plus 2 in the back get me there?

and as far 520 525 n 530 pitch i was thinking about going in the middle for the 525 depending on how much more a 530 kit would be. thanks mangs.

 

Clutch it up! Powerwheelies spell trouble expecially in 2nd gear. On an F4I you can clutch at low rpms in 2nd gear no problem. I no this because I run stock gears on mine and can ride seat standers for miles if need be.

 

:YEAH Will do...Just got it like 2 weeks ago so i'll take my time with that haha. Thanks mang.

 

Just to help your learning process I will help explain. When in 1st gear at any rpm (when learning probably at idle), using your index finger slowly pull your clutch in just enough to release your gear and then womp the throttle just a little and let it out. Play with it till you're comfortable and always cover your rear brake. Staggered position was easiest for me to learn the balance point. Good luck and I suggest a cage or sliders just for insurance
