My one started to rattle inside the expansion chamber months ago[1], plus the end can is rattling. The people in the shop I got it from lost the warranty form for it on account of it sitting on their workshop floor for a few months. VE supplied it, but they haven’t been very helpful at all, saying that they’d need the pipe sent back to them… then they would decide if it’s a warranty job. That would take time, and meanwhile, my scooter is off the road. Plus, I don’t trust the shop enough to send the pipe away and get it back in one bit. Is there anyone in Scorpion I can talk to about this? Not going to get anywhere with the shop or VE. [1] Took the shop months to 'look into it' for me.
