They seem difficult to come by sadly, the last owner of my Vmax got rid of it when he had it and I haven't been able to find one either. How much of a problem does it cause with tuning the carbs, I am still struggling to get my Vmax running right and am wondering if that could be a part of the problem. So I would definitely jump on the opportunity to get one.
Sorry, I dropped the ball on this. I work 12 hour days Friday though Sunday and they've been killing me with overtime through the week. Glad you found one.
