I am new to this forum so if I ask a dumb question please be patient. I hope I can fix find help for my problem. I have a2004 Trx 650fa starts hard when cold (20 degrees and lower) and runs bad until it warms up. Any suggestions??

Try using Rotella T-6 5W-40, helps mine in cold weather, didn't have a problem all winter

Sounds to me like it is running lean. Seeing how it is an alder model I would suggest doing a series of things that it probably needs anyway. Clean and overhaul the carb ( do it well with the help of a repair manual), drain and dry the fuel tank thoroughly, Clean the petcock, adjust the valves and replace the spark plug and air filter. Ehhhh.......go ahead and change the oil with a good brand of FULL synthetic oil .

Dumb question here, but are you using the choke?

This model has a fuel primer located by the carb, Honda recommends a 5 minute warm up period. The choke alone will not be good enough. If you are, performing these steps you will need to look at other causes, if not start here. Oil is very important, know what you have and what you need, some oils will damage your clutches.

Try the choke along with synthetic oil.
