while I do have deceleration popping, I also have a knock while decelerating in gear. the knock is not felt but heard. i'm figuring the decel popping could be related to tune issues, original plugs, etc. the bike has original air intake configuration, no mods have been executed on this bike performance-wise.
I have read several threads about the update kit but did not see mention of the decel knock symptom i'm hearing. perhaps I missed it. regardless I am concerned about this noise. as a reminder, the bike is going to the triumph dealer this Saturday for a "post-purchase inspection". at that time they will help me determine the overall condition of the bike and what needs to be done to insure long term enjoyment.
if there's a silver lining here, 12 yrs of manufacture and history should offer much on how to address most of the early year bugs.
