Hi guys
I have a NC23 Tri Arm and have taken it out for its first real ride and found that it has a very intrusive buzz/vibration at about 6 - 7 rpm, there is another a little higher as well and it it is felt through the bars and the pegs. I mention it as it is far more than i have experienced on any other bike before.
I was wondering if the carbs being out of balance could be responsible or there was anything else particular to the bike that could be responsible. Can anyone Help please
Cheers

carbs out of tune wouldnt help but valve clearances would be first on my list? when were they last done? clearances out cause alot of viberation.. same as mine until i did them....massive massive difference in bike. not saying its that but from my own experience it was the solution...plus doing them is only a good thing anyway

Is the front wheel properly balanced?
