TT600 jetting issues...
1984 TT600 to be specific. I can get it to run OK, but the tuning is wrong. As it's jetted now, it takes a few kicks to catch, and then barely stumbles at 800rpm with choke on, and dies with any throttle. After 30sec to 1 min it will idle at around 2000RPM. After some stoplight waits in 70F weather it will begin to idle slower, but straightens out if I run the pilot mix screw leaner. The average ride will leave me with a somewhat yellowed fender from carbon soot.
So essentially, I can't get the right range for it to start happily in the morning, and run right during the day. Does this sound like a float bowl issue? The TT600 carb runs a comparatively low float level, with richer jets, than the XT600 carb. Is it too lean, which is why I am overcompensating with the pilot screw?
