F4i sprocket chain kit
 

I wanna be able to rip some good second gear wheelies but I don't wanna lose too much top end any suggestions on what and where to buy
it's almost fall and wanna do some work to the bike

Highway or lot? Highway wheelies are simple at stock gearing in second.

Stay stock.
I went -1 in front and HATED the highway RPMS. ...Was always looking for 7th gear.
Stock 2nd gears are easy just use more rpm and slip that clutch quick. Also bounce the suspension to preload the front forks to spring the front end up easier. timing is everything.
3rd gear really takes some juice :icon_wink:

No lots for me I just want a nice strong kit that's made of steel rather than aluminum I think maybe -1 in the front would be nice for me
I rarely use anything past 5th gear anyhow

sportbiketrackgear.com might have what you're looking for.

lol then I have an extra -1 front steel sprocket, hardly used, if your interested..20$ shipped.. You can even keep your stock chain length, installs in 10 mins..

You mentioned that you don't want to lose top end...if by that you meant just cruising on the highway id say to stay stock..

"I rarely use anything past 5th gear anyhow" Then i have just the part for you! :icon_goofygrin::icon_goofygrin::icon_goofygrin:

I'm most likely going with the rk
quick acceleration kit , because I also need a new chain mine is stretched to sh!t
