The 2058 pipe is great on the CRF engines, but the Discovery have a "normal" crankshaft, so I dont know if there will be the same difference.
How is the Discovery responding to 2013 and 2057 pipes?
Discovery reacts the same way as King/Tebo engines. The porting and timing is very similar, and the Discovery likes the 2058/2013. 2057 doesn't work so well in the US style tracks. Some euro guys can get it to work, but we never really run it.
