Fist off, I used the search feature and after reading over 500 of over 1000 posts came to realize there was no solution (much off topic discussion) and most of the posts were many years ago. I'm reffering to the abrupt noise when using the throttle in low rpms in the first couple gears, not a shifting issue. I'm on my second used gtl in the last month, my first one was recently totaled. While there was some drivetrain backlash on the first one this one is way worse. I have both bikes in my possession now so doing. an a/b comparison is easy. It has nothing to do with riding or shifting style, same rider different bikes different results. Some talked about a software update, had warranty service, used different oil. returned the bike or just said live with it. Were any concrete solutions revealed? It there is a mechanical issue and an easy parts swap with my first bike that might be an option? My first bike only had 6000 miles on it and was recently serviced before I purchased it, this bike only has 3600 miles and other than new tires I don't think any services were done to it.
