TOPIC:

I just had my carbs cleaned and syncronized. The cold start problem i was having is now gone...Woo hoo!
But, i have noticed an excess of vibration and a loss of power at the top end.

Any thoughts?

Thanks

I'ld go back and see whoever did your carb work and explain the problem. Sounds like a sync or maybe even a fuel starvation problem. How do the plugs look? Are any of your exhaust pipes running cooler than the others? Does the bike sound right?

Not sure what kind of set up you're running, but I had a noticable loss of power in the high r's on my 77 kz650b1 until I changed the primary jets up a step. Not sure why it'd have done that to you after cleaning and synching, but my problem stemmed from the wrong jet sizes. Hope it helps.
