Eh bi's. Got my 09 yz450 around the start of june. Drove it almost everyday this summer. Great bike, wheelies like a dream and no major problems just tires and bearings. I have noticed lately that its been kicking over rather easy and im wondering if this is a sign that im losing compression in my motor. It does usually start 1st kick in the morning but i know theres a lot of people on here that know more about serious engine things than me. Just wanted to hear what you guys have to say about this issue. Thanks. Stay golden.
