Inliners International Forums General Discussion Hi Performance Lump kit results/gains?

Thank you!! Any unmeasurable benefits like better throttle response?


this engine has a mild cam, zero deck, 9.5:1 CR or so, and minor tweaks here and there. I kept the stock valve size it's a 230 and I was hoping it would have better low end that way. It won't be a high rpm build. I guess more of an "optimized", efficient little motor.
