hard to start at elevation

5 posts in this topic

I have an 04 wr450. YZ cam and JD jetting kit. I am having problems starting the bike when it is at any elevation increase from the valley. Only when it is cold. I usually have to pop start it and it runs great. Once running or fires once it starts fine the rest of the day. any ideas ? :cry:

If you give me your elevation and the temperature, I can give you a close approximation for your jetting. Or Indy might show up and give you the perfect combo.
