Hey Bengt!
My motionpro carb synch sucks mercury (Hg). I tried Dinqua's suggestion of switching tubes and found a moderate difference. I switched them several times and split the difference. My bike now runs as slick as snot on a gold tooth.
Please read my signature. I was finishing a rebuild on my Yamaha 650 carbs 29 years ago when I received a call from one of my wife's workmates saying she had a miscarriage (i didn't know she was pregnant). I hurridly(sp?) tightened the last carb to manifold bolts and took off to the hospital 10 miles away at full throttle over 110mph. I happened to look in my mirror to see the familiar California Highway Patrol's steady burning red light through a trail of blue smoke. I had forgotten to tighten the first carb to manifold bolts, started sucking air and burned a hole in my piston. I pulled over, told my story to the cop, and he had sympathy enough to let me go (knowing i had to spend a bundle on repairs). Anyway, after a short one cylinder ride to the hospital, I found out that Raynea was not pregnant but suffering gastroenteritits from oysters we had eaten at the Morro Bay Oyster Festival. Please read my signature - it happens to all of us. Besides, when I see another Triumph, I almost always look at the headers - they're supposed to be blue (if you like the retro look - that's just retro Triumph). Just ride safe. It's only a few months before that "Move To Alabama Dust" hits the ground again.
Your Brother,
Dennis
p.s. I am about to prepare my hard bags for painting. Wish me luck!!!


Ride Safe, Dennis Triumph, it's how I live and what I ride.
