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. Both the pipe and silencer are after market FMF bolt-ons.
I decided to clean the carbon out of the pipe and repack the silencer...Oven cleaner was used to clean both. A propane torch was used on the pipe. I cleaned out all the small holes in the silencer with a small drill bit. Man what a long task that was. Standard household insulation was used to pack the silencer. I tried to match the amount of insulation that was originally stuffed in the unit. The original packing was drenched with spooge and the majority of the holes were plugged.
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 finally 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.
I think the key to finding the solution may lay in the fact that this only happens when I'm aggressive with the throttle opening. Slowing rolling into the juice does not produce this prob.
I'm going to take apart the Silencer again. I'm absolutely positive there is not a blockage in the pipe.
Here's a though/question.
If an exhaust gasket is missing or badly dried out will this cause my problem.
Just remembered that I only have one exhaust gasket as one broke while I was taking the pipe off..
I know, I know ( ..... I'll go buy one tomorrow....hehee
thanks.
