Throtle ? Hand keeps going num

[casey88]

I have had my kfx450 for 2 years now and everytime i ride my thumb goes num. i no it has a lot of viberation so i bought flex bars and anti vibe inserts and nothing changed. so i moved the throtle around and still nothing i tried lots of little things also , then i also have a kfx 400 as a pratice bike and it never goes num the only thing that seems different is how light the throtle seems , does any one no of any spring kit or any other ideas to make this go away i am willing to try anything. thanks kc

Have you thought of using a twist?

i have tried it on other bikes and i never could get used to it

ive gotten so used to it. when i first started racing on a mx track my hands would be numb after a few laps. i found out my problem was that i would grab and hold the bars SO tight i would take the vibrations from the bars through my hands. my solution to this was simply to get comfortable holding on with less grip. very scary at first but now i am so used to it it doesn tbother me anymore.


also i have tusk bar risers stock fatbars and stock grips etc. no vibrate inserts either. ;)

i belive there is a return spring in the throttle if you take that out it will be eaiser, i kno wthere is a spring on the throttle plate and it sould be enough that u dont need 2. but that is true with the holding on tight, is you have a vulcan death grip on the bars you will get tired faster
