Honda Spree and Elite 50 Forums

So as I lurk around the forums I see a few different threads about jetting, BB size, exhaust, Gears, Contra spring size, clutch spring size, Variators, variator weights, etc. etc. I was thinking that we can sum everything up in one post to help point the newbs in the right direction with a good starting point. Some of the things I get confused over is size of carb compared to jet size exp. bigger carb smaller jet? Also, heavy rider (250+), heavy contra spring or lighter? Higher RPMs=lighter variator weights? Gears.... tall, short, BB, fat/skinny riders, top speed?

Ok so I think you guys get it now lets see what we can come up with. I do realize this is all really based on opinions and will probably start a few * matches, so let try to stay away from that. LetÔÇÖs get facts, set-ups, and tried&true know differences.

Thanks for the info and I will update and put the info on this post as it comes in!

d***, no one?...............

I think it's a good idea but the variables are endless.
Maybe you could figure something out that would make this work.

You gotta give it some time for replies too, I'm sure others are out blowing things up.

Yea, that is what I am trying not to do.

OK let me try to start a guideline of what I am asking. I have based this on the AF16 motor and a BBK.

Variator: Top end speed vs. Take off
Stock AF16 = ?
Stock Ruckus = ?
Polini = ?
etc. = ?

Variator weights: Depends on size of cc, clutch, and variator
Heavy = lower RPMs but needed for BBKs
Lighter = higher RPMs for more response/ stock

Contra springs: Bigger riders vs. lighter riders
1000 = ?
1500 = ?
2000 = ?

Clutch springs(the 3 small ones): How high the RPMs are on take off
1000 = ?
1500 = ?
2000 = ?

Big bore size vs Carb size: This would be more of a general idea
Stock 50cc = Stock carb 16mm?
72cc = 24mm? 28mm?
80cc = 24mm? 28mm? 30mm?

Carb size vs Jet size on a BB: also very subjective but needed just as a guideline
24mm = main/pilot
26mm = main/pilot
28mm = main/pilot

Gears: I know absolutely nothing about this subject. I have seen that is all depends on weight of rider, BB size, and goals.
Gear size? + heavy rider (250+) + more top end
Gear size?+ heavy rider (250+) + faster acceleration
Gear size?+ light rider (>249) + more top end
Gear size? + light rider (>249) + faster acceleration

Pre Mix ratio: More as a poll of what is used, good/bad, and type of oil used
50:1
36:1
etc.


Please feel free to add in your set up and info!!! Everything added will be helpful to someone either good or bad

Its either derestricted stock or a quality bbk, both are reliable but a persons weight is a factor and there is a science to to it just don't get addicted to speed like i did
