1990 KDX 200 with FMF gold series pipe, stock silencer, boyseen reeds, air box lid removed, clean oiled UNI filter, and extensive porting.
I have been wondering if the stock silencer in this combination could be a problem. Should I spend the $ and get an aftermarket unit.
Pros, cons please. I am trying to tune this thing in. I bought it last month and it does not run like it should. I am tuning the carb up right now and I am hoping the port job was not done poorly.
Another question: What effects will I feel if the port job is done wrong? Right now all I can see is the intake runner is hogged way out and smoothed considerably. Makes me nervous.
Thanks.
