Gear changes on my 2011 D675R racebike have become progressively stiffer over time, to the point where the top of my toe is sore at the end of a day, and neutral is almost impossible to select. I'm running standard shift pattern with Attack Performance rearsets and the stock quickshifter. The quickshifter rod has clearance through the frame and is at a right angle to the arm. I have a Sato shift spindle holder mounted. It's the same oil that I've been using for 5+ years, changed at <500km intervals. I do 6 race weekends plus approximately another 6 track days a year on the bike.
I've owned the bike since new; when I switched to the Attacks a couple of years ago, I noticed that N was a bit harder to find than with the Arrow rearsets I had before, but it's become much worse since then. It's very, very difficult to get the bike into neutral, even when pulling the shifter by hand, it usually takes at least five attempts. From first gear, I have to pull up on the lever very hard, and even when gradually increasing pressure until it finally clicks, it shoots past N from 1st into 2nd, or vice versa in the other direction.
No issues with clutch slippage, and it engages properly near the end of the lever throw when leaving a stop. I'm thinking that years of quickshifter use might be a bit harder on the internals than using a clutch. Are there any parts that are likely to be worn which would cause this behaviour?
