Yes, exactly... stock muffler has great torque in first!
Stock muffler has trouble starting though, needs choke...
it also has some lurching in the first few minutes of riding,
but once past that, it runs fine.
Now my custom exhaust has virtually NO trouble starting, no choke used... it also doesn't lurch, ever...
but that first gear is toast, second is at least serviceable, and everything higher seems fine.
As mentioned... so close, yet so far.
A thumper without low end, is just a scooter.
P.S. Heading over to the HD dealer dumpster this evening...
see if I can find myself something to play with! hehe!
