Re: When cold and starting up it is hard to shift to first gear?
I don't think it is a "warm/hot/cold/fridgid" issue. It is a mechanical alignment situation,... NOT a problem.
The gearbox doesn't have "synchros" like most cars. So, they rely on a slight "movement" of the gears to enable alignment. You can easily demonstrate/experience this by putting the bike on the CS and clicking through gears. I'll bet that you will have to move the rear wheel, just a bit, to allow the gears to change. (Try moving parts by hand with engine OFF so you can feel it better.)
To 'eliminate' this.... when my bike is in neutral and RUNNING, (APPLY and hold FRONT BRAKE) I ease out on the clutch WHILE ... I put just a LITTLE bit of downward pressure on the shifter TIMED exactly as I squeeze the clutch.
Since the "input shaft" is being spun by the engine, it quickly aligns and allows the gear to be selected... never fails.
Another method... with engine running, pull in on clutch, HOLD front brake, apply slight "shift" pressure... if the bike goes into gear, "okay"... no problem.. If it doesn't go into gear, keep pressure applied and "EEEEEEAAAASSSSSE" out on the clutch just until the bike goes into gear.... Then you can ride off or squeeze the clutch to stay.
