Just curious how your theory relates to the same issue on bikes that have balanced exhaust systems like the Valkyrie.
No prob snake, I have no doubt that you and Isaac Newton are correct about whether 50 lbs hanging off the ride side with a moment arm of about 10 inches would have any effect... Just a matter of degree - I don't see any bikes that lean at a 20 degree angle going straight.You'd think the designers would place the engine mounts at a point that would balance the bike with stock equipment, wouldn't ya?
I had the left side wear on the front also on the stock dunnies. I have switched to Metzler on the front and Car tire on the back. I believe there are a lot of factors involved in the left side tire wear. I believe one is left side drive. I am not as experienced as some of you guys so I could be wrong.
