name that tune

does it do it every time or what? does it do it if you were going to start the bike instead of having the kill switch turned off?? but i dont think its your starter clutch but maybe some thing worked loose like on ricks bike with that screw kinda sounds the same to me

its a 18mm spark plug but if you can find the holy grail of sockets (18 mm) then it will work i use what ever is the closet fit and that works for me

is the noise still there after you changed plugs?

well i am glad the noise is gone and now your a little closer to getting that on the road i know you have been wanting to for awhile now so just take a spin down the road you dont need a front brake (i ran a year with out one) just use your rear and slow sooner

man i just want to go for a ride some time soon and i am sure you will learn how to use your back brake only...
