I have learned something from you. I did not know what make those pipes are. They sure are mean sounding.wingrider wrote:Congrats! Those pipes from Two Brothers are mean sounding!
She’ll drink gas like it is going out of style, but you will have a blast doing it!
They are great for fault finding. When the engine got up to operating temp there was an occasional popping from the right side.
So easy to figure out which one, just put your hand in front of the outlet and feel which one is popping and simply trace it back to the offending cylinder.
Turned out to be the middle cylinder. Plug had good spark, and was not totally black or wet, so I did a quick compression check and the reading was only 80PSI.
Knowing that the shop had been working on the head I took off the rocker cover and on checking there was no clearance on the exhaust tappet.
Loosened it off a bit 'til I had some clearance and compression came up to 130. Rocker cover back on, Spark plug back in, and she started up and ran smooth.
No popping. Will have to delve deeper though and do a proper compression check while the engine is cold.
She is a dream to work on everything is 'just there'.
