hey people I’m new here and I have a problem ^^ so I’m now doing the roller feel and I buy a derbi senda 50ccm and I want to throttle it but I already get that I have a very high performance loss and I want to ask if I can’t compensate the loss of performance somehow with scratching?? and is that allowed?? say the ones at the tuv what?? sry really have no idea about this ^^ thank you in advance=)
