ok.. bucking has stopped when i move the clip position to middle (plug readings still totally white)
moved it down one clip mark (2nd up from the bottom)... and bucking came back at 1/2 throttle.. check plugs again after a chop block (WOT in 4th, hit kill switch pulled in clutch)
stopped, and removed plug.. totally totally white!
today i sprayed starter fluid around intake area, maniforlds.. head.. all over the place, NO change in idle at all...
weird thing was, is i sprayed some in the air intake.. just a dab, to see what would happen, and the bike sounded like it was going to die.. (didnt rev up like i thought it should)
i didnt spray much.. just a tiny squirt.. tried it again, further away, and even a littler amount.. sounded like it was going to die..
but anyhow, it didnt rev, or sound like it was going to die when i sprayed it anywhere else....
this has got me STUMPPPPED!!
a 190 main.. and white plugs.. hmmm
