Thanks for your reply Mark, I run a disco 300tdi and that has the egr blanked off, its a great mod to do

. With the sas pipe on my LML I'm not too keen on the heat that the pipe seems to get going to the valve. In a nutshell and between you and me I've blanked off the pipe at the cylinder head end. Just like a 300tdi. My scoot runs crisper and sharper with it blanked. PS you cant see the blanking plate so hopefully my warrenty still stands or its a two min job to remove at the road side. According to the LML 200 4t service manual the pipe needs cleaning out. My pipe was starting to fill with carbon. According to Barrus air is 'sucked' into the engine to mix with the exhaust gasses, whilst on the exhaust stroke of the 4 stroke cycle I pressume. Exhaust stroke blows not sucks

. So if its drawing air from the filter through the valve I cant see why it needs cleaning. I will keep you posted on it progress Mark. Well done on your great result with Barrus

......also hats off to Barrus for sorting a happy ending.
PS. I have also removed the inner filter in the air box and left the outer one insitu. When you compare the filters of a PX or a direct bolt onto the carb filter, the 2004t filter is like a ruddy bath sponge

any thicker and I'm sure the engine would implode lol. thanks John
