The last couple of mornings (they've been quite coolish), I've started my ZZR250 up and let her warm up for about 5 minutes or so. When I've gone to move out of the garage and go to engage first gear, it stalls. If I go back into neutral, start up again and go into first gear its not an issue and won't stall. It only seems to be when I'm in cold conditions and its the first time I engage first gear. Firstly, is this a problem? (I suppose its better if it didn't do this!?) Do I need to tighten my clutch lever a little perhaps? Is it possible the oil is the wrong grade? I think I'm running 10-40 at the moment. I have noticed previously when the outside temperature wasn't as cold, the first time I go into first gear with the clutch pulled all the way in, sometimes the bike will lurch just a tad (like the gear actually engages a bit). I've had that happen on two bikes (both a GPX and ZZR) now so am assuming that is normal to some degree the first time you put the bike into gear when the bike is cold. I think my stalling problem is probably that not only it grabs like it does sometimes, but maybe because of the cold weather the gear grabs even more and stalls. Does this sound feasible? Any ideas?? All 2c's worth welcome.
