07 Rev won't restart once it's warm

[660canuck]

I've got an 07 Rev with the 08 updated motor installed about 400km ago. It ran perfect when I had it out late in November. Took it out on New Years to take the kids for a ride, started and ran perfect, but took 20-30 pulls to restart after shutting it off. Went out to silent last week, started fine first thing in the morning, ran great all the way up the trail, took a break and shut it off, didn't want to start again. Changed the plugs and after several pulls it started and ran perfect. It was brutal to get restarted all day.Forgot to put my scratchers down for the trail on the way out, over heated and had to shut it off again. Could not get it to restart, had to tow it out. Can anyone shed some light on this?

Are the plugs wet or dry when it won't start??

is your coolant valves turned off to your carbs

I actually had a similar incident with mine... ended up using the choke to restart it.... WEIRD!! Any ideas?????

Plugs looked a bit oily, not really wet when I changed them the first time, but they ha 400km on them. After that they were dry. I am thinking plug wires or something electrical. I will start checking things out on Monday. Coolant valves are off.

Mabe try a new power relay. It's the one on the Lh side above the air box.
It's usually the other way but Mabe its getting wet after riding.

Check the one way valve on the fuel tank vent line.

have you had any problems with the recoil falling apart..... maybe something got into the stator

do you hold the throttle when you pull? I always crack the throttle a bit on both of my revs (old 05 and current 07) when they are warm. Otherwise they are a biotch to start.

just make sure it doesn't run away on ya

I had the same issue and it was the relay. Its a five dollor fix. Change it a give it a try. It is a 1" black cube near the fuses. if you don't have a relay unplug the head lights and see if it starts, if it does it's the relay.
