can a carb snyc issue cause a lean codition

[bksdesign]

I synced my carbs by the site window after installing a new throttle cable. I think they are in sync but could not see in the window well. Now the bike is running good, real good. When I parked it, it seemed kind of hot, the black hoses between the toomey exaust parts were smoking, not leaking smoke, smoking like they were hot. I had rode it hard, but am worried its running lean because its running good other than the smoking from the exaust. Can the carbs be out of sync and causing it to be lean?

 

Thanks

Nope do not think its coolant. My bike does not have the overflow tank under the seat that is in the manual. and the smoking rubber is under the seat area..

ok.......2nd post about this...... so on your bike that you just bought and are having this problem with.... did you put the toomey pipes on it? have you modified it at all? What jets are in the carbs?

No the Toomey pipes were on it when I got it.

 

Its been running alright. The only thing I noticed was the carb overflow hoses would leak gas sometimes, there would be a little wet gas spot on floor of the shop in the morning. I was putting a thumb throttle on it. I set the floats to 21mm. It has 280 mains and 25 pilots and ran fine. The only things I changed was the syncing the carbs, and I adjusted the pilot airscrews to the setting from the toomey web site. They were at 11/4 turns I set them to 11/2 turns. since then I have set them back to 11/4 turns. I will get back to ya once I ride it and see if it smokes again from the exaust joints. I had polished all the aluminum, and the exaust, maybe I got polish on the rubber joints and it was burning off.

 

Thanks
