Lithium smears too much to my liking. The actual "paint" leaves a really easy to read pattern without a lot of transfer meaning only the contact patch area transfers.
I've not been into the case yet but the gearset does not look to have any adjustability other than maybe fore and aft through shims. I'm interested in what the heel, toe, power, and coast sides looks like citing these areas did not make noise when new and what has changed. Once I know that information, I can move towards correction. Many of the particulars of helical gearing apply to spur gearing also but spur is much stronger, easier to manufacture, and less expensive but always noisier in operation.
No secrets here nor am I going to try to make any money from this. However, and with that being said, most bikes have inherent flaws with them. Ever ride a Honda Valkerie, (sp)? That high gear whine in a lot of them is much worse than these on the Ventures. I like my bike a lot and wish to keep it for quite a spell longer is my only motivation and several feel the same way. Only real difference is I'm not willing to live with it as is.
