Hey guys, I am trying to sell my 99 XR600R. The last two people to look at the bike have noted that there seems to be very little compression when kicking it over. This being my first bike I have nothing to compare it to, so I would have no idea how hard it should be. Bottom line is: I have had no problems with the bike since I bought it, it runs fine, doesnt burn oil, starts fairly regularly given 5-10 kicks to prime it, and blows no smoke. I have never really had a need to use the decompression lever to get the bike over TDC, but hold it down while kicking before starting it cold. Does anyone know what the problem could possibly be? It seems to be preventing knowledgable people from buying the bike, and honestly I would hate to sell it to someone else and for it to be a problem for them. One kind bloke on the chat recommended checking the valves, should I check this. Does anyone know the location of any good instructions? Cheers, Pete W Australia.
