Dont think the Lokar will solve any of your problems. Had similiar issues with my crossram car. The lokar throttle cables work great on a stock type setup with maybe 1 carb. On something that requires a lot of foot pressure i was less then impressed. When you have to step hard on one the stainless wrap actually compresses/expands and makes for a sloppier peddle. I ended up having a commercial cable company make a throttle cable for me. Look into what Mr. P. said above. it looks like you can change some geometry and make it work alot better. then if you still need some more travel, you can heat up and bend the pedal arm and get a little more throw out of it.
