If you think the SV's bad you wanna try my Kwak,bloody thing cuts you in two
Its most probably the bike thats doing it to you. I had a horrible tingly numb sensation in the last 2 fingers on both hands,from vibration through the bars I assumed. Went away after not riding the bike for a few days but I did worry just as you seem to be doing
I wouldnt consider changing bikes unless the pains unbearable,maybe fit a small foam pad on the tank to protect the fellas?
