1) Installed a new 115mm Dr. Pulley variator because I broke the fan wheel taking off the old to switch out some lighter sliders. It came with 3 washers and said to place 0 to 3 between the back component and the fan wheel to adjust the range but gave no indication or guidance whatsoever which way installing them would take it. It is a nightmare to get my CVT cover off as the exhaust is bolted to it(KandiM2 buggy). Any idea which way adding the washers – increasing the space between variator and the fan plate would take it. I am looking for the most low end torque possible. My guess is adding them would increase the distance between the two plates making essentially a smaller gear decreasing the torque but not 100% sure. any insights or guesses appreciated.
2) The switch out with the variator and the lighter sliders did make a big difference in torque and am pleased with the bang for the buck. But I still want to optimize without doing the more involved work. the kart ramps up to max rpms rather quickly and has better acceleration but tops out at the RPM limit pretty quickly. So what are your thoughts on the performance CDIs. We don’t have a tach and neither my kids nor I are going to have the wherewithal zipping around on trails to closely watch RPMs even if we did. Are there any that raise the limit to something before it redlines or are they all just no limit. Have you heard of or seen damage to the engine when these performance CDIs are on – if there is a decent chance then it’s not worth it. I’ve seen just as many reviews saying they didn’t work as well as stock as I have saying they helped. Again any insights appreciated.
3) I already have a 120 main jet and a UNI performance filter which did help increase hp. The uni is short though and tucked up under some wires and a frame and not sure its getting enough air exposure. Would building some type of L shape either PVC or hose component raising the filter away from the engine and more in the air free up flow or have the opposite affect restricting the air in the longer bent tubing.
Thank you in advance!!
