throttle and/or chain idler upgrade?

many have used the stock idler pulley as it comes out of the box , others have switched to a skateboard wheel that has been modified to have a groove in it for the chain . And still use the same mounting bracket . And even other members have used something of there own fabrication for a bracket and pulley . Unhook the cable from the throttle at the handgrip and pull on the braided wire part to see if you have a spring that is working properly inside the carburator . It should return when you release it . The throttle cable itself should not be mounted with any sharp bends in it only long flowing loops especialy where it comes out of the throttle handle and where it goes in to the carb . There is some crappy looseness in all bike kit throttle set ups and that is the nature of the beast . Motorcycles have a nice crisp throttle action that these kits are lacking .

Best of all remove the idler completely. It serves no purpose on most bikes.

I was having problems with the Idler, so I just did away with it. As for the throttle, it is crap. I just got an old dirtbike throttle off of ebay, aluminum, heavy duty, much better. You may need to modify the cable housing stop on that end of the cable for a dirt bike throttle. Another cheap easy throttle fix is an old brake handle, I used that one for about 3 weeks until I got a twist. I was kind of partial to that pull throttle, but it took a couple times to get used to it as I grabbed it when I went to brake...that was fun
