the original throttle setup on my max 2 was getting hard on my right hand . so i changed to horizontal handles . instead of making new complete levers , i bought 2 weld mount tubing clamps for 7/8 '' o.d. tubing from mcmaster carr ( part # 3015T26 ) i welded a 4'' long 7/8 '' o.d pipe 4'' long centered on the threaded plate side of the clamps ( take them off to weld ) . then tightened each one on the tops of the steering levers . bought a twist grip throttle set for 7/8 '' o.d. tubing with a 60 '' long throttle cable . works great and much easier on my hand . and i like the way it steers . johnboy va
