Vacuum Line Full of Gas

Just cleaned the carbs and installed them. Bike starts and runs but just noticed that the vacuum line from the front carb to the fuel petcock is full of gas - do I have it hooked up wrong, is the carb flooding itself or the valve defective?

Looks to be hooked up correct. But if there is fuel in that line, to me it means your petcock has a prob! I would say the vac diaphram has a hole in it, that I think would be the only way to get fuel there. The PC is super easy to rebuild, cost about $28. I think I have almost a whole kit (used-I recently redid mine and saved all the parts as they were all good) If you want it,its yours for postage!

04-3,200 miles bought July 2011 with 928 miles. Loaded with acessories to many to list here, see my albums for more details! I also make a custom tank bib specific for the 750 if anyone is interested, ck my albums for some pics.

With the engine running I can see fuel coming from the petcock to the carb in the vent line. Luckily the dealer had a new petcock in stock $65, so I got it, problem solved. The old petcock is trash, opened it up and full of pitting and gunk, not worth saving.

Heck for $65 I'll probably just buy a new one for my bikes instead of the rebuild.
