I have a 2009 raptor 700, I'm running it with a single DMC pro quiet, DMC fuel controller and air box lid off.

Problem is my silencer is getting so hot it's burned the DMC sticker off the silencer !?

Why could this be ?

Thanks in advance

Have you checked your plug or had it dyno tuned? I would bet you are running lean. Does it pop or backfire?

I've checked the plug and it's a little black but I've never had it dyno'd.

Does this mean it needs more fuel ?

You are running really lean. Take it out at night, and ride around for 20 minutes, it looks cool when the pipes glow red/orange.

Maybe try to adjust that controller a little until the spark plug is tan colour. run turn off check spark plug then half throttle run turn off then check splug again for tan colour adjust accordingly. But a dyno run is your best bet!
