I had my original motor modified and tuned, with stroker crankshaft, high CR, cam, flowed heads etc, but the starter could always do the job. In addition to the previous starting tips, when pressing the starter button, make sure to keep it firmly pressed, so the engine turns over until it is running.
If it is recluctant to turn over briskly then clean your battery terminals, make sure they are tight, but also clean and check the other ends of the main battery cables. Check battery condition and claimed CCA (Cold Cranking Amps). If the battery is old or cheap, it may not have the oomph needed.

You can overheat the starter if you use it too much.

I read through this whole thread and can tell you from experience, recent experience that the folks telling you its not the seals are most likely right. I have a mild cam in mine (EV46) and I was going through a ton of oil. Turned out the valve springs were bad and causing the seals to get crushed, oil was leaking straight past the seals. Now the reason I say this and still support others who've said its more likely rings is.....I had no oil on my spark plugs at all, clean and dry! Even loosing a quart+ every 5-600 miles. Id start with a compression test than maybe pull the exhaust as others have suggested.

Don't ever let someone convince you that a Mikuni HSR42 is not a great carb, it is... also, I never have to twist the throttle before starting, ever, cold or warm. (But that's MY bike) just saying..
Pull choke(enricher),gas on,push start button fires right up,couple seconds, choke off and raise rpm slightly and lock throttle to warm her up a bit.
And I still haven't changed out the 1985 ignition just yet !!!!
