What pipe 2013/2058/2050/2060/2090/053/2035/2039 what is good and If anyone has compared it to a crf 3/5 port. I run os speed and blue head os and also the bo2 right now, and also have my b5&b5 pro and bo1a ninja and 5 port discovery to compare this to so if anyone has anything to add please do.
Thanks
That is the engine that made me love Orion engines. It has a great power band and great top end. I ran a 2013 pipe with it but with a 2058 it still does great. Mine has over 7 gallons on it and it will still run non stop and eat the 7 port Novarossi engines alive. You will notice a difference between the orion and your OS engine, if you are heavy on the trigger it might get you into trouble as it has lots of grunt. I know it is more than capable of handling any 5 port on the market when tuned correctly but I have not actually ran against a b5 or b5 pro in Vietnam, but I have ran against OS, Novarossi, RB, Nvision and there is no comparison.
