What's best way to get some more power out of one of these quads
Gsi-mark, not sure about the pm pipe. We are using a pro shark pipe w/ good results. The “shoe spring” are located in the variator and the torsion spring goes behind that, both are rated by RPM’s. The roller weights go in the front clutch. Overall not a hard job but you will need an impact wrench (easer) and make sure that the belt seats all the way in on the front and back.
In theory shaving the head helps. But first you should look around on here to learn about squish clearance before sending the head to a machine shop.
Hi wot about reed valve and a cdi and a air filter wot main jet would I need for a polini air filter etcWe run a Kasea 90 and a DRR 90, both have the Aeon 2 stork 90cc. We use the Pro Shark pipes on both as well. I don’t know much about the Cobra 100 but assume not much different other than maybe a slightly bigger bore and maybe a few mm longer crank. I do know the Cobra makes a bad ass race ready mini.
