medley Posted December 15, 2011 Report Share Posted December 15, 2011 my shee had a twist throttle on it when i got it and i put the thumb throttle on it and it is stiff. how can i make it easier to push? it has keihin 28mm pwk's on it and i think the springs in them are too stiff.

06specialedition Posted December 16, 2011 Report Share Posted December 16, 2011 I've heard guys cutting the carb springs. Make sure the springs stay the same length. There is a thread on exactly how to do it, use the search function i'm sure you'll find it. Quote Link to comment Share on other sites More sharing options...
bladesracing Posted December 16, 2011 Report Share Posted December 16, 2011 I think a stiff throttle is just part of having a banshee. Quote Link to comment Share on other sites More sharing options...
Starwriter Posted December 16, 2011 Report Share Posted December 16, 2011 Easy springs from FAST. $5 each. http://www.farmandsandtoys.com/partdetail.asp?partid=119 Contrary to popular belief, cutting a coil spring actually makes it stiffer. You only end up with slightly less tension because of less preload on the spring. Yes, if you are careful, with trial and error cutting, you can make it sorta OK, but the right way is to buy FAST springs. Quote Link to comment Share on other sites More sharing options...

Starwriter Posted December 16, 2011 Report Share Posted December 16, 2011 please explain how cutting a spring makes it stiffer? Take a coil spring, (any spring) and unwind it, so it's a straight bar. Clamp 1 end in the vice. Grab the end and try to bend it. Now cut the bar in half and try to bend it the same distance. It will be harder to bend. Coil springs work on the same principal. They're just wound up. When you cut coils on a car to lower it, the suspension gets stiffer. Quote Link to comment Share on other sites More sharing options...
So Cal Suspension Posted December 16, 2011 Report Share Posted December 16, 2011 please explain how cutting a spring makes it stiffer? Coil springs are just coiled torsion springs. As you compress a coil spring, it actually "twists" inside of itself. This is a basic principal of leverage. The shorter the torsion spring, the less material there is to twist, thus creating a stiffer spring. duh. Quote Link to comment Share on other sites More sharing options...
bansheesandrider Posted December 16, 2011 Report Share Posted December 16, 2011 stiffer usually means you have changed the spring rate. by cutting a coil out, you have not changed the spring rate or the spring. also when you are talking about the white trash way of lowering a car, when they cut the coil, the person has not made the spring stiffer. they have just taken length of the spring. this shorter length means there is less travel till the spring is completely compressed and the spring will bottom out soon. Starwriter and MattSCSS are correct!!!!!!!!! Matt's explanation is almost word for word what I was taught in suspension class in mechanic's school. And I would think as a suspension tech, Matt would know what he is talking about. The bottom line is when a torsion bar is comparatively shortened or made bigger in diameter it becomes stiffer and a coil spring is just a torsion bar wrapped into a cylindrical shape.

guns4children Posted December 16, 2011 Report Share Posted December 16, 2011 Now if you flip the spring upside down..... Quote Link to comment Share on other sites More sharing options...
