could you tell me about some of the mods done to this ski?

aaron King I can tell you that if you want to gain similar performance, use a freshly built and trued crank, twin carbs, a professionally ported cylinder, a properly setup head, and a good pipe setup correctly to the motor And most importantly use the correct pitch to let the motor rev into its relevant powerband You may prefer/need to use aftermarket ignition also

Thanks for the reply, I have a fresh 650, I did a core swap with SBT so the crank is trued and welded. performance wise I'm running an SBN 44, jets are 115 low, 145 high, 2.0 NS with 80 gram black spring. West coast intake manifold and west coast exhaust, 86 ignition so no rev limiter, stock 86 water box rcjs tri scoop intake grate and 16 pitch skat-trak prop with a D cut ride plate... Would bumping the compression up give it a nice boost worth writing home about? also i know the 16 pitch prop isn't the best an i hear a lot of people say i should try an 8/16 or 9/17 would running one of those be a significant improvement over my current impeller? I'm all about good punch but I do need speed to wake chase. I'm finding it tough to reach a happy medium.
