Yesterday I went to do the first service on my bike and approximately two hour on the bike last week. First off there's a big hole gnawed through the filter, just the outside layer. The filter in 100% oil free, dry as a bone from the dealer. Pull it off and the airbox is littered with mouse crap! Couldn't believe it. I,m sure it came from the dealer this way. Also guys I'm having a real hard time starting this thing. When it's cold (it's only about 35-40 degrees here)I use the choke but if it does start, (most of the time it won't with the choke on)the kickstarter kicks back because it idles high, and that really hurts the ankle. Then I turn the choke off, it will fire but not run. If I have one of my kids outside, I get them to pull the choke out the second it fires, and the it starts fine, besides the fast idle. When it' warm it starts first kick with no choke and idles fine. What do I adjust?
