Its leaking from the bottom, what will happen? WIll it be ok to ride or does it need to be changed now?

it will need a rebuild...

you probably won't ruin it by still riding with it cause the worn parts will be changed come rebuild time.

but as more oil leaks out you will loose rebound and compression softness...... it will be like having just the spring..... it will annoy the hell out of you.

Just like my kids 250x shocks lol

Where can I get a rebuild kit, or new shocks?

Works suspension has a rebuild kit, Race Tech has the gold valve kit, Eyeball Engineering rebuilds shocks. Also a really good shop thats here in California Nor Cal Moto Tech, They do re valving re sprining, rebuilds anything the only downside is you have to ship your shocks out to them. There going to overhaul my suspension pretty soon
