Message: [QUOTE="Bucket, post: 155245, member: 24008"] I recently purchased a '90 kdx200 that came with a pipe,silencer,reeds,air box cover removed and had been jetted accordingly..the bike ran great. I decided to clean the carbon out of the pipe and repack the silencer with household insulation..After preforming this mantainance the boging problem started. Now the bike bogs whenever I quickly snap the throttle wide open.The lower the rpms the more the bog. I'm talking total lack of power...as if someone turned off the power switch. It will bog,then stutter,, then it will finall build rpms as it should.The bog will happen for about 2 to 3 secs. If I roll into the throttle the problem does not exist. Help,,,,did I repack the silencer too tight/loose. Do I need to rejet. Does it seem to now be running too rich or too lean.... Doh!! Thanks in advance :) [/QUOTE]
