I just bought a 2003 gti le rfi with a blown engine. I bought a SBT engine and swapped. All went well. The question i have is what is the MPH vs RPM i should be expecting. This thing just seems slow....at 4k RPM i'm getting about 22 and 32 at about 4600. It isn't fast out of the hole and takes time to get moving. When i compare this to my 2001 polaris virage txi the polairs is significantly faster. Does this sound right? I'm wondering if i torqued something too much in the jet because i rebuilt that....Any ideas?
