The first thing( cheapest tp try ) I would do is put in a new NGK plug gapped @ 0.45mm this smaller gap will lessen the load on the ignition.Maybe check your chassis earth this will only take a couple of minutes to clean up.
If that does not work I think the next easiest thing to try is swapping out the HT coil / cdi box.
I think the wipers from SKF KIT35M will work. You could also try Gas Gas p/n G280000 and maybe Fantic p/n 364.02.00.5390
Good luck and please post what worked.
I think you either have the bike flooded or you do not have any fuel going into the motor. If you stick your nose at the end of the silencer after you have kicked several times you should have a fuel smell.
50 to 1 , to 80 to 1 should all be fine.
Regarding riding obstacles, you need to find some people to ride with. You will learn best in a group setting.

Standard tyre pressures are 4psi rear and 6psi front. Everyone has there own idea regarding air filter maintenance. The are 2 oil screens to check and 1 oil filter to change. The fan kick in time will vary quite a bit depending on the ambient temp.
lineaway, regardless of bike brand most of the rear brake components are Braktec. The Braktec made components do not seem to be as good as the AJP brand were in the past.
