I bought a used 03 YZF 250 a little while ago, and it turns out that I'm using it almost exclusively for trail riding at the moment. I'd like a little input on what mods are most effective for making it a better trail bike. I don't want to kill it's track capabilities, as I'll probably end up riding a little track at some point, but I imagine I'll end up riding a lot more trail.
So far I've got lights and some bike protection, but no performace mods at the moment. I don't really want to go spending money blindly, so I'd like some educated reccomendations (I have no idea what I'm doing).
The first thing I'm planning on doing is the drivetrain, because mine is pretty worn out... any gearing reccomendations?
Other things I'm thinking about include a bigger tank, 18" wheel, heavier flywheel, and maybe a quieter pipe, not necessarily in that order.
I live in Colorado, so the riding is pretty steep and rocky, and I am ususally riding between 6-10k in elevation.
Any feedback is appreciated.
