yz426 backfire

Recommended Posts

Hi finally got my bike up and running again. I change my stator and bike finally runs. Even though my ohm-reader check ok on the old one it was still b ad. New stator has lighting output and works with the stock flywheel good buy at 80 bucks

Well while I was at it I did the coil on spark mod.

and replaced the Diaphragm assembly

5JG-14940-18-00, but think I ordered the wrong one.

Bike runs but takes me about ten kicks. Even with both hotcams installed.

Carb has the 170 main and 48 pilot jets. and 3.5 turns out on air screw. I'm at sea level. 6 notches down needle. Cleaned it out before install too.

I also notice that the breather tube is leaking some oil after a ride.

I'll post a vid up. It sound like the bike is idling up and down without touching the throttle. When I throttle up you can hear it backfire on deceleration.

any advice.

Should I go with a bigger pilot jet?
