Stage 1 or Stage 2?

I want alot more acceleration so I can pull out of turns hard and fast also for amature dragging. I read that the stage 1 won't really effect my top end but obviously it is better acceleration than stock. The Stage 2 is sort of made for stunters but they said I will lose 5-10% off my top end. Say my bike goes 165(it can stock) I will only be losing at most 16.5 mph of the top which puts me down to around 148ish topend which is fast enough, but will the stage 2 be too much of a change. Will it be too hard and quick to go up through the gears when normal riding? Thanks

you must be talking about final drive components, as i've never heard them being referred to as "Stage X kits"...

and 165 on a stock F4i? down hill, with hurricane force back wind, and a swift kick in the ass maybe...

what's the sprocket tooth change from stock?

change of gearing would get better results. But if you are set on a jet change go with the stage 2.

yeah considering you mentioned stunters, i am assuming you are talking about gearing changes....also that you are talking about losing top end (typically with a quick acceleration gear change)....

short answer....changing your gears will get you faster and you'll lose some top end....

long complex answer i won't get into....you can change your gear ratio so much so as to make it have CRAZY low-end torque...which is essentially what the stunters do to get the front up real quick...that being said...you try and accelerate hard with a big gear kit, you're gonna loop it....drag bikes i think have bigger rear sprockets, but they have an anti-wheelie bar to prevent the front end from coming up....you're going to have to evaluate exactly what you want...and yes a big rear gear is going to make you shift like mad in normal traffic...you're going to hit your limiter MUCH quicker....

i'm presuming this IS a gearing... because a properly tuned Jet kit would not effect one's speed...

or the fact that i think he's got an F4i...

I am sorry for not stating that I am talking about sprocket kits. Just for the record, it was a gradule down hill slope that "someone" hit 165 with just a slip on. Anywho, I dont have any intentions in "stunting," I just want have mad acceleration to a point that I have good control and not losing too much top end. What do you think my limit is as far as sprocket changes?

you can go as high as 14f/60R (which is just straight up ridiculous)

but if you want to FEEL a LITTLE more acceleration, i'd go for a 3:1 setup.

-1, +2 will give you exactly what you desire.

I agree... BIG difference in acceleration. Be careful though because the front end will want to stand up in 1st and second under hard acceleration, especially if you're talking about exiting a corner while in full gallop...

i had the stage 1 kit on my 01 f4i, first which is -1, +2, and it was good, i don't think i lost any top end, but then i put the stage 2, which is -2, +2 on it and i think it is great for the so cal canyons it pulls so much harder now. you do have to have a lil bit more careful with throttle control though, becuz it seems a bit more twitchy now, but not 2 bad. yes under hard acceleration it does want to bring the front end up, especially in 1st, 2nd is great though. stage 2 sux on the freeway now though becuz at like 80mph i am turning like 9k-10krpm. and i think i can only top out at like 135-140mph.  but i also go to the amature drags and with the front end strapped i turned a 11.6@118mph... so if your willing to deal with it on the freeway, i think it's a great everywhere set up 

Man, that must suck to only be able to go 135-140...especially for city commuters.

i don't go that fast on a regular basis but i did wanna c just how much the change would affect the top end.  considering how many rpm's i was turning at like 80mph. i think it's a pretty accurate account of the new top end cuz i had my cuzin pacing me on his 954rr with a speedo healer, but yea u right how often would u need to go that fast anyway.

lol

Couple questions. 1: What does a stock f4i do in the quarter mile(average)? Cuz I thought you should be able to do 10.6s ish. 2: If anyone knows what their quartermile time is with the Stage 1 (-1,+2)?

From the sounds of it as of now(still pending), I think the stage 1 will be better for me do to the fact on the turnpike you have to go 80-85.

A little off topic question: Whether a Stage 1 or 2 sprocket kit is on my bike, if I pop my clutch to drag, will it stand up or burn out if I am leaning forward? I am afraid to pop my clutch right now with 46rear, scared it is just going to pop the front end up verses burn out. Any info is appreciated!

Thanks

Doing a burnout is pretty much pointless on these bikes... But if you must, make sure you have a big handful of front brake.

As for the 1/4 mile... CLICK LINK

Go with the stage one, stage 2 is probably much too extreme for everyday commuting. Plus it will put more wear and tear on your chain/sprockets/tranny/engine...

popping the clutch will for sure bring the front end up, these bikes really don't make enough torque to do a burn out unless your grabbing the front brake and trying to light'em up 

Anyone have any info/experience with this?    http://www.moto-heaven.com/store/cart.php?m=product_detail&p=237 or http://www.moto-heaven.com/store/cart.php?m=product_detail&p=257

lol I really hate how they categorize it as Stage 1 and 2.  Just so you know, the 520 kit refers to the chain size (pitch/width). So 520 chain is smaller in comparison to a 525. And the idea behind it is, that it is less rotational mass. And less rotational mass means less work for your engine to have to keep that chain spinning around to power your rear wheel. 520 chain will also most likely wear out a bit quicker than a 525, but it's also a bit cheaper.

If you go with a 520 chain, you'll need 520 sprockets as well. But it seems as if that web site offers it as a package anyway.

I want to thank you for pionting out what exactly the 520 was compared to the 525.
