having never changed the plugs on my bike I spent the outrageous $8 per plug and got honda NGK's anyways I fouled a plug earlier by giving throttle while the choke was on oooppss!!

anyways I tear the plastic off and the seat and tank to discover the plugs are dman hard to get to. UNable to remove that plastic/rubber divder I basically ripped it out without causing damage. It looks like hell to get it back into place. Is this divider important? Is this the correct method of changing plugs?

I'm changin the plugs now and wanted to see if I need to struggle and get the divider back in befoer I put her back together
someon lemme know I hope I can do wihtout i its a BITCH to get out/in

thx!!!
