When the bike starts, it sounds like there's no power - sounds like its blocked?

SOURCE: my dr 250 1984 has low compression

your carb got stuck and it sounds like your rings are burnt out like u were running to high of an octane or something in your gas

SOURCE: White smoke Air Cooled Suzuki dr 200 with oil next to carb

usaually white smoke means you're burning too much oil.

SOURCE: 2005 DR 200, sat over winter. Charged battery,

Sounds like a battery problem mate, give the battery a charge and see how it goes, If it has been sitting for a while it sounds like it might be a carby problem, so clean out your air filter, give her an oil change and give the carby a clean and then try kicking her over with a fully charged battery

200° is quite warm...
If the engine wont turn over, probabily you have a bad battery, a bad starter or a bad starter relay, or bad connections.

A hot engine has more compression. If the full battery power doesn't reach the starter it won't turn over...
