Thanks squeeze for the good info. I have been through the carbs completely and are clean. I didn't check the jets for size numbers. Next up like you say is vacum leaks. The diaphrams are in good shape. shawn

Yea pilot mixture is what i adjusted, sorry for the confusion. I agree it does seem like a lot but the bike was extremely rich before this going by the plugs (wet with gas not oil and black). They are now a brown color. What has made this a pain is the bike was somewhat apart and im just putting the peices together as i go. The charcoal canister "to carb" hose was disconnected and plugged. I left it plugged and went to my 83 for a baseline adjustment on the pilot mixture screws and went with that. I know that 83 seems a bit much at 4 1/2 turns out but it's been that way for 40,000 miles and the plugs are a nice light brown. Now, what i was confused with was i thought the pilot air screws where the air screws to change the mixture at idle but changing the adjustments has made a huge difference all the way through the revs not just at idle. Calling it a pilot air tells me it should just change the mixture at idle. Correct me if im wrong on that. As far as the canister hose being disconnected, there is no nipple for the hose to connect to anywhere on the carbs. Again thanks for all the help you guys have passed on to me for this. shawn

Ok, I got it running pretty good now. I ended up turning the air screws out from near bottom to 4 turns out. This seems to be where it likes it. My 83 is 4 1/2 turns out, the way it was when i bought it. Thanks for the help. shawn

Thanks for all the info. This is a great site with great people. I'll keep you posted on what i find. Shawn

Yea the reason i asked is because it is plugged off right now and the bike runs very rich, so rich that it at about half throttle it runs flat, no power. just kind of dies.

Sorry for the confusion. Your thinking about the desicant canister (air dryer) for the air suspension. The charcoal canister sits on the left side of the bike beside the engine mounted to the cross brace. Its for the emissions i believe.

hello, im new to post here and am trying to figure out where the hose marked carb on the charcoal canister goes as there is no fittin on the carb for this hose that i can see. The hose routing is marked on a sticker on the tank and does say "to carb". The other two hoses are marked atmosphere and tank and they are hook up already. Just cant find the fitting for the hose that needs to run to the carb. I do have a 1983 VR and it doesn't have the canister so i cant look at to compare. Any help would be great. The bike im working on is a 1985 VR. Thanks Shawn
