Thought I Was Finished And Was Ready To Ride

Alright so I have been working on getting my bike up and running. It was sitting for two years in a garage and would not start. I changed the spark plugs, oil and a new battery. I also drained all of the old gas out of the carbs (the guy I bought it from left the old gas in the bike) Now the bike runs but only with the choke on, at first it stalled right away when I started to take the choke off, I put some AMSOil P.I and it seems to have helped a little, I can take the choke off about half way but as soon as the RPM's Get around 1k the engine stalls. It will not start without the choke on even when the engine is warm. I am not sure where to go from here, not sure if I need to sync the carbs, take them off and clean them or drain it again and try seafoam instead of the AMSOil stuff. I tried adjusting the idle stop screw but that does not seem to help, it will rev up to about 5k and then drop down to 1k and stall.

What about the fuel filter?

You need to clean the carbs, fuel filter is not a bad idea, but I can almost guarantee you that your jets are clogged from the old gas gunking up.

The Manual says that I can service the vacuum chamber and float chamber with the carburetor assembled. Is this enough to clean them out or do I have to break everything down and separate the carbs from each other?

You will need to remove the carbs from the bike, turn them over and remove the float bowls. No need to take apart the carb assembly. NOTE: if this is the first time, these tiny bowl screws will be hard to break loose and one can easily strip them. Place a good tip screwdriver on them and rap it a couple of times with a hammer to break the threadlock. If the screws have allen heads, then bike most likely has a jet kit as they use these to replace the sucky stock screws.

The manual will note the location of all the jets. Remove and clean with carb cleaner. Make sure you can see through the tiny holes. Now you'll know why they are so easy to clog. The cleaner is under high pressure and the over spray can ruin/discolor plastic and other surfaces (BTDT) so be careful when you do this.

Relax, you are almost near the completion of a VFR resurrection! :wheel:
