1987 KX250 What Am I Missing?
« on: May 09, 2025, 01:26:34 AM »
Hi All,
Sorry, somehow this landed in 'Introductions'.Can the moderator please help delete that one?

My '87 KX250 is hurting my brain. I bought it in a pretty sad state, rebuilt the top end, bought a knock-off carb (old one was toast, oem's on eBay were no better, at that time), replaced the petcock, replaced the stator, ECU...After quite a while, a few days ago, it finally kicked over and ran, sounded good, responded to the throttle, but I had to go, so I killed it. It never started again.
There are some oil droppings from the exhaust manifold, but nothing scary. Could an old reed cause so much trouble? It seems ok to me. I have a decent spark, it was getting fuel, so I am thinking it may not be that.
I was really thinking I could go out the next day and start it, but now I'm kinda bummed. What gives?
