Update:
Finally got out to Carnegie over the weekend with the new TX. Swapped over the suspension, carb, RKTek head and the Clake. Carb settings didn't cross over the way I wanted (new bike is lean in the mid, didn't have the same explosive power the other one did) so I spent time playing with needles and clip position. Close but still need to play some more.
I did however get to ride with the Clake and love it. Throw is pretty long (it can be adjusted) so the engagement range is longer than a regular one. Pull is easy one finger and you can slip it all day without your finger cramping. I noticed no lag in how the clutch reacts, so much so I'm wondering exactly what they did in that housing....flat out works great.
It's kinda' ugly, like a big lump on the bar but the added control is totally worth it. Not a must have but if you're riding techie stuff it will allow you to dial in what you're doing to a finer degree.
Now to swap out JD red for an NEDW and see if that gets me what I want on the carb...With the first bike I think I moved the clip one position and was done. Wonder if the Fatty is causing the change? Stronger mid will want more fuel, JD red gets it there but I'm getting some staccato at about 1/8 throttle (too rich off idle).
