Does anyone know the best way to un-plug a stock 1984 fl250 exhaust pipe? I have heard to use a blow torch or even a heat gun to leaving it in the campfire. Does anyone have a trick for unpluging thoses old pipes? Also, does anyone know the best way to repair a cracked intake boot?
What makes you think its plugged up?
These OEM pipes are lined with insulation about 3/8" thick then they have expanded metal over the insulation to help keep it in place, this makes the pipes quiet.
You will hear and read all over the place about cleaning a 2 cycle pipe using heat or flame this does not apply to OEM pipes but does to aftermarket pipes that has no insulation inside them, this is pure ignorance, stupidity advice coming from people with no attention to detail.
My first 2 stroke was back in 1972 I have owned them ever since I have yet to see a pipe that needed cleaned on the inside and or where cleaning it did any good for the owner other than psychologically enhance their manhood.
I have seen countless times where the SPARK ARRESTOR was dirty and plugged up.
I suppose if your one of them morons you see riding around with your jetting so rich a blue trail of smoke follows you their could be a significant build up of carbon in your pipe, I doubt you will recover any measurable HP by cleaning the pipe, MORE gains would come by properly jetting your Engine.
Search the internet on this subject you will find hundreds of people ho will bet their life your 2 stroke will run better if you bake your pipe, make sure you ask to see the proof other than their 'feelings' , good luck!
