I ordered an IDS from Zanotti's yesterday..... said not in stock should ship possibily by next Monday.They will press bearing in for an additional $12.00. I do not have any issues with transmission ie. whine or rattling....... overall motorcycle has performed well with a little over 18,000 miles. Getting ready to change out rear tire (seems like I just did that a couple of thousand miles ago) tires wear out quick when you ride. Hope this addition is is all it is hyped up to be. I figured that it sure couldn't hurt.
