Fixing my 1986 yz490

Recommended Posts

I have an old 1986 yz490 that I recently got from my grandpa. I've been trying to get the bike running but I just can't. The first day I got into the airfilter which was a mouse nest. It's all sorted out now I have a new filter and everything but it still won't run. It will start but die out after a couple seconds. I would love it if I could get some help. I think it's within the carb.

Take the carburetor off, completely apart, and clean everything thoroughly with spray carb cleaner (don't soak anything in ChemDip). If you're going to be fooling with vintage (where this thread will go when the first mod comes along), you're going to have to become intimate with wrenching on stuff..
