If you clean your chain, and lube it regularly, vortex are perfectly fine.

 

Whats your stock rear? Like a 45 or somthing?

Up 15, will probably drop your top speed from around 160 INDICATED (145 trueish speed)

to around 115-125mph top speed




I run a 60t on my f4i, and I get around 120mph top speed, and I sit around 8k on the freeway gonig 75


edit: my friend runs +20 -2 on his f4i.. still tops out around 95-100mph.. Not really needed, really just stupid gearing.. But it's still streetable. He still follows us down the freeway at 80mph with his bike screaming at 11k lol
One thing thats fun with that gearing though lol.. Poping it up in 1st, quickly shifting through the gears to 6th, and keeping a 6th gear wheelie up at 30mph lol

 

thats funny because you're an idiot.

 

thx about this info

 

ic this place has alot of hostility in the atmosphere

 

will it go past 20 mph?

 

 

Bro dont go anything over 55..

!

 

i went -1 in the front and went 64 teeth in the back. it is completely up to you what you want whats cool with someone else you might not like
