Great choice on buying the LST2. You will love it!

The LST2 HSN comes very rich from the factory. You can start tuning it down quickly during break in.

The non-shift is also expected. At about 1/2 gallon you will see it start shifting. Things need to get broken in. Plus with the engine being so rich it's hard for the RPM's to get high enough for a shift.

Once you hit the 1 gallon mark with this MT...it will start opening up!! I moved up to Sidewinder 30/12 and love it! Also, you may want to consider the RD Logics dual stinger pipe. Loud as h*ll and gives the Mach427 some big time increases in performance.
