My 4rt offers no resistance from the throttle its just too light for my liking, I would prefer an action like an old bike pulling up a heavy slide against a big spring.It has a long pull throttle tube which also concerns me as i find it hard to get full throttle at times although I seldom need full throttle.But I fell i may get in more trouble if the throttle action is too quick although its not a hard or expensive mod to do anyone got any ideas what are you guys using ?
