I have a small pump with the plastic taken off just like you mention and I even used it for a while but the bulk it comprised in its wall mart bag along with the plug kit was for me just bulky. Also the long wires needed to accommodate it were always getting twisted up on the bumpy trails which had to be cleaned and repacked for each different motorcycle, street, quad, dirt bike. Pretty soon the kit started looking pretty rag-a-muff and then would not work because the solder points would crack off or the exposed pump motor can get wet in the rain and cause a short with no fuse to the batt. Since one pump kit doesn't work between three bikes, I settled on three wallet size CO2 kits which stay packed, dry work great even when your bike battery is dead, or more importantly low on juice, not to mention much faster in seconds compared to microwave minutes. Having the choice between a CO2 Kit and a pump with a long tail and bare connections, I guarantee you will naturally gravitate toward the CO2 kit IMHO.
