The last couple of times it stuttered I cracked the throttle & the bike died.
When it dies it does it suddenly.
The last work I did was go from thruxton to TBS needles.
I even changed back to the Thruxtons.
Same problem.
Even went back to stock needles.
Same problem.
The TBS sure do make a dramtic difference over stock.
I put the TBS in again last night.
The Diaphrams are seated.
I have experience in knowing the symtons of them not being seated.
I will go out & see if I can fin the sensor.
My Triumph shop manual is hard for me to read.
