2010 yz450f

Hard starting when up in the woods is it valve timing or could it be something else

Hard starting when up in the woods is it valve timing or could it be something else

Technique?

I have had this happen to me (2011 model) every now and again in the woods. I have just done all new valves and piston at 66 and valves at 77 hours

i have the technicque correct but it will just not fire, so i hold the throttel at "full open" and kick it 3 - 4 times, then let the throttel go "closed" and it will fire up on the first kick.

This is what i have found that works for me when i cant get the bike to start when in the woods.

Hi there I own a 2010 yz 450 I am 5 ' 11'' and 170 lbs the only reason I mention my weight and height is im no big guy. I noticed this issue also the first ride ever on my yz but with a solid day of riding and feeling the best spot to throw all I got at the kick start she fires 1-2 kicks every time,I believe Yamaha has a video on proper kicking technique

check it out helped me a lil

Thanks zombie that might help
