i did mine at 500 miles. then at 1500 then 3000
no it could not make the bike smoke beaocuse you would have a bunch of extra play with the rocker arms or the cap covers making the valves be closed and not opeing enough for full power but what could do that if you do not get you valves ajusted from a long periord of time carbon will build up on the valves and prevent the valves from closeing fully which means time for a valve job.if the valves DO need to be adjusted could it possible make the bike smoke?
