809 misses after 1/4 throttle. Please help

Rowdy1132 · Feb 22, 2010

Just started missing saturday, idles fine on all 3 cylinders, as soon as you go past 1/4 throttle starts missing, and egt is about 100 degrees cooler on middle cylinder, plug is alittle wet. Tried switching plug wires still middle cylinder wet. Checked power valves, they're ok. Gonna check reeds tonight, really stumped, any help i'd appreciate...thanks

Round slides or flat

They are flatslides rack. I'm thinking it's the fuel pump, reeds look good. Jets are good, carbs good, compression good.

a stater going bad will do that.

Not the fuel pump, gona try stator next. What a pain. thanks guys

Check to make sure the slides in the carbs don't have the corners broke out. I had an XCR8 do this and that was the problem. May or may not apply but an easy check.

Greetings Rowdy 1132,

Consider replacing the center plug if not all three.

Good luck.

Craig.
