I have a 2002 dt150 that is hard to start after it's been run and sits for a couple hours. I run it about and hour and sit around 4-5 hours before leaving. It takes it forever to start and I'm wondering if it is fouling out the plugs on the last leg of our trip. We idle probably 20 minutes to our destination. Cranks up fine after sitting for a week. Thanks for any help or suggestions.

I pulled the plugs and found the gap was around .022". NGK website gave a gap of .039". Cleaned and regapped the plugs to NGK specs and seemed to correct the hard starting problem. Cranked right up after the same scenerio this past weekend. I still need to pull the plugs and see what they look like now. I'll post after this is done.
