I need help. I'm new to bikes and I have a 99 xr200r (have had for 3 months). Just had valves adjusted and timing chain adjusted (at shop) and kickstarting now seems harder than before. Now today I kick started and when I went down on the kick it seemed to just free kick after about 1/2 way thru kick stroke. It now won't start and kicks free w/ no resistance or compression. I assumed a bad problem and parked. When I roll it while in gear it definitely rolls easier than before the kickstart problem. Does this sound like a timing chain break? If so, is this an easy backyard repair? or What other problems might I need to be concerned with? And what about cost of repairing?
