|Receding valve seats |
My understanding, from many years on this forum, is that receding (soft) valve seats were a problem on the earliest Ninja 250s. I'm not sure in what model year this got resolved, but valve wear hasn't been an issue on my 96 and it has similar miles. If you were to search old posts, you might find backup for my recollection, but it was apparently very common for engines over 50k miles.
