Alex I ordered a New chain & sprockets from volar, their hh brakes are good, this one has 14,000 miles O rings falling off when I spin it, it gets real tight then real loose. Iam certain this adds to the noise as well.
I am getting it ready for the track next spring at njmp, I had previously ridden pre gen 250 & ninja 500.
There are a good hand full of new gen 250s and 300s so Iam fixing one thing at a time.
