Bought a de-restricted aerox 50, then fitted a doppler s3r exhaust to it, the standard exhaust works fine, but with the doppler exhaust on, it barely moves. I have tried using lighter roller weights, and it seems to make no difference at all :banghead: Any suggstions as to why this is and how I can sort it out? Has anyone fitted the same exhaust to their aerox and what did they do to make it work? All help is much appreciated! Thanks, Elliott.
