Incase anyone reads this, I was able to fix the issue. The bike was not able to run with the petcock in the on position only prime. The previous owner did some odd work to it and left the petcock vacuum line unplugged. I removed the kleen air system and plugged the petcock into the carbs and the bike starts up right away now. I also added three washers under each needle and removed the snorkle from the air box with a kn filter. I have a slip on Vince something exhaust.

My question is although the bike seems to be good now, it is around 35 degrees out.. I’m sure that it will be slightly running rich once the weather warms up...

Will removing the CAT in the exhaust help to lean out the system? Even if it only leans it out 1% do the fellow forum people believe it will achieve a leaning out effect? Thanks I appreciate your opinions
