Might it be u "insert" e seat not "skill" enough. i also ve to insert rider seat a few times before get it. Pillon seat i put cloth so open often and use to it. But rider i not used so never manage to get it right 1st few times.
For ur side mirror, if stock type, u just need to use strength. But others ve advise me not to else over time will be loose. If u wan to "open/close" ur side mirror, can consider getting after market like rizomo? Got chiong type also. I think those easier to open/close.
Or just go jb during off peak.
