2 into 1 carb setup

[Ruko]

I just got my girlfriend's Banshee all together finally... but the problem is she hurt her thumb last year and the thumb throttle is too stiff for her. I tryed a twist but that is just plain dangerous... so I'm trying to make the thumb throttle as light as possible. I'm planning to cut the springs and go to a Honda thumb throttle but would switching to a single carb make much difference??

i know exactly what you mean. Get the cascade inovations longer banshee billet thumb thing , it actually adds more leverage so its easy to gas it . ive only rode a banshee with one once , and let me tell u , felt like it had goped carbs it was so easy to mash the gas.

try the longer thumb throttle , its just like whjen you incrase the travel on a swing arm , the leverage is greater so you have to run a more stiffer spring........

Do NOT cut those springs.

It will make the initial pull easier, but harder as 1/2 throttle or more is reached.

 

If anything, lightly sand and smooth the outside of the springs for a lighter pull, that will make the tension easier.

 

I have a thumb throttle extender from RMATV that I put on and took off immediatly cause I didn't like how it looked. It clamps to your stock throttle.

 

Sure, a longer lever gives you more leverage...it also make the throw from closed to open longer too...so, balance out the good and evil.

 

If you're interested in the thumb throttle extender I have, throw me a few bones for it and shipping, and it's yours.

its under cascade banshee > ez push > many stiles to choose from

I bought a whole new thumb throttle from Magic...it's still not much easier:

I plan on getting new carbs soon, anyways...

I'm using the Moose aftermarket thumb throttle and that helped a lot. Then i put on a 2 into 1 last month. I don't think there is a bike out there with an easier pull now.

How do you figure it will make it harder at 1/2 throttle or more??? Less spring should be less tension...

[Kunda]

yeah but da further yer spring stretches da more tense it gets, by makin it shorter ya just make it hit a tenser point quicker.

[dajogejr]

Honestly, because I've done it both ways.

I thought the same thing...told someone they were silly...they turned out to be right.

 

While I don't have a scientific explanation, I do have a bill from the dealer for a few sets of springs...

 

Cutting the springs does make it easier for the first bit of the pull...then it is just as hard, which...in turns, makes it seem harder because the first bit was so easy...

 

Sand off around the outside of the springs....

 

I wish I would've used a fish scale or other measuring device to document it...

[carter71]

It's simple physics, the spring is a long wire wrapped in a spiral. The longer the wire, the more flex there is at the other end. therefore the more wraps (length) you have the more flexable it is. Of course you have to figure in the wire diameter if you change to a different spring.

Exactly...that's why you grind off around the outside of the spring for easier pull.

Less diameter of wire, less resistance...easier pull...

I put a single carb on my shee and it is way easier push than my buddies bike with stock carbs. And the single carb is way easier to rejet.
