Looking for information on the 7 port crf? Has this engine not been that good of a seller or is it just a weird coincidence no one talks about it? I just got one and it seems to be hard to find specific reviews, I'd like to know how it's overall performance has been, how the bottom end is and how top is!? 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
