2002 yz250f. Long story short, bike was starting first kick cold/hot all morning trail riding. I crashed, broke my decomp lever but continued riding after re-alligning front end. About 10 miles from camp I killed it (had shut off and restarted bike multiple times since then) and all of a sudden the kick starter would not budge at all like it was seized. Being this far from camp, I finally put everything with my heel I had in me onto the kickstarter and it "broke" free and I was able to start the bike. After this though the bike would only run for a minute or so before dying in the middle of idle or riding (i was only in 1st or 2nd gear), and after this the kick starter would "sieze" up again. I broke it free about 4-5 times total before we gave up and towed the bike back to camp. I am getting a new decomp lever on the way home, and I am hoping compression was the only issue with the kickstarter not budging since I did not have the lever. This is the first time I have used the bike without properly using the decomp lever when starting it. My main question is, what if any damage could I have done by kicking down on the kickstarter that hard to start the bike and using it without the decomp lever? I plan on changing the lever today and will update, and then checking valve clearances next week plus other work I have to do it. Any insight would be much appreciated..
