Yeah, I just put on a supertanker (KTM version) and the lines are pretty dang close to the pipe on the throttle side.
I used a larger diameter line to make a double thick line to resist the heat, and I also used it to help route the line up and away from the pipe. I think it came out really nice actually.
And now, for the grand unveil... my brandy spanky new 530 EXC after (most
) all of the farkling and required mods have been made.... I do need to make a heat sheild for the exhaust side blinker before it melts off....
