I have a 01 TRX 500. It's been beat on. But runs like a champ and doesn't leak. Long story short there is no choke hooked up totally gone. I have been using the primer bulb on the carb as a choke. Is this ok for long term? I'd like to get the choke back on but I need to order a new steering shaft first and really don't feel like tearing the front end apart again.
