does anybody know if a certain motorcycle tyre pump exists?
Use any pump and attach that chuck to the end of the hose.
I have a cheap foot pump with a flexible hose and an angled chuck like that – obviously doesn’t help unless you are carrying it around with you, an alternative is to fit right-angled valve stems or to carry a flexible hose with you (I couldn’t find suitable angled stems so cable tied a flexible hose to the bars, so I could use any pump that was available).
no transmissions should slip. if it does then it could be low on fluid, the clutches are shot or the transmission filter is dirty.
