Higher idle when hot?

Just wondering if it sounds normal for the idle on my '99 400 to raise about 200 RPM when it gets hot? Everything works fine, no hanging idle or any other problems. But, the idle definetly goes up after riding a while and then stopping compared to when I first start it up. Thanks! -Adam-

Yeah thats normal...my 426 does the same thing! Not a big deal!



I get my kicks on a 2001' YZ426!

Yep. Takes about 15 minutes to find it's normal idle. Like motoman393, mine does this as well. My KLX does it too.

Thanks guys, you're helping to ease my mind all of the time! -Adam-
