Fist principles.....are you sure that the fuel is getting to the carb? Are you tickling it and does fuel come out when you do? If the bike has been standing, the carb will almost certainly need cleaning and all the passages tested.
The crank seals are probably due for replacement, but the fact that no sign of fuel is getting to the top end is one of the first problems to deal with.

Have you tried draining the crankcase?

Could be a blocked pilot jet?

Stale petrol!! This modern rubbish goes off after a few weeks. Does it start OK after its warmed up? Also may be spark plug, a 'hard' one would be specified for racing, try a 'softer' one. like an NGK BP6HS

Even if the crank seals are past their best the engine should still run, albeit poorly

Seals are cheap & easy to replace on a single. one on drive side and one on the flywheel side fitted in the back plate that holds coils. Couple of hours work, you dont need to strip whole engine. Leaky seals will effect starting but ok when engine is running and crankcase pressure overcomes any leakage.

If you have fitted Electrex World ignition and the carb is not blocked, has the correct parts in it and the pilot is OK, it should be a good starter. My TES is anyway.

Check the c/case drainplug as was mentioned and carb.
