Thought people might find it interesting about a sled that I helped a large friend set up. Started with a 2015 163 pro. First thing we did was change it to a 174 3", then add a Silber turbo with Justins new updated BD reprogrammed stock ECU. Then I had him get a TKI belt drive so we could get a 2.57 gearing for him, and a 180/ 300 secondary spring, with helix set on 42/46 and the weights set up correctly at 74 grams. He's running about 8# boost with 50/50 av/ 91 non ethonal. Lets just say I've ridden it and watched it run, it's a screamer. He's had it out about 7 or 8 rides and it has carried him with out a glitch every ride all day. Plus the smile on his face says it all. Oh ya by the way James is a large man, ( lets just say over 365#). will keep that part under our hats, ok. I'll try and get him and some others on here and have them tell ya what they think. Not all of us have to ride double every time we ride...lol...sorry James
haha
