Bit of advice needed. Got a rising fighter for the kids which I put my rebuilt cvas on keeping the kit springs as it is so light. Despite having 3 hole pistons and one down to 30wt oil it still doesn't return well and the front and still bounces like mad under power. It's a funny little buggy but would like it to be a little less wayward. Do I go even lighter on the oil? If so how light? Or drill out the piston holes? 

Cheers!
