Ha....I have a 99 yz400f and it has a compression release lever. It is a BEAST to start regardless...I pop start behind quad or use a hill (using compression release) more than I kick start it. Kicking it, u are supposed put choke on...slowly push kick start through the easy compression till it bites, pull compression release before you kick and let it go when you kick. It is a real beast to start, unless its warm...thats for sure.. the manual for the bike has the exact instructions on starting it in this manner. Good luck...mine is a beast of a bike and I am lovin the 4 stroke over the 2strokers I used to ride years ago.
I had a 426 and it started on the second kick (cold) EVERY time. When warm 1st kick. I had people get on and kick till they were blue in the face and not get a spit out of it. There is definatly a "technique". Figure it out and these are VERY reliable starting bikes. Mine was...............
-Pull the decom lever in and SLOWLY kick it over until it was JUST past the hard spot "top dead center".
-Release the decompression lever get a "full" bite on the kick start and give it a kick.
