Ok, I have inspected the needle settings and they are correct. I have ensured the throttle bodies are in sync and the air adjustment screws are at the correct 1-3/4 setting. It just seems really rich at the low end until it gets to about 4,000 rpm. Not sure what else is left to do. I have about 100 miles on it since I started riding it and no fouled plugs. In fact, I was on a hill and it really did not want to let me start from a dead stop up the hill as the power was just not there.
Also as I take off it seems rich or doggy until I get it up to 4,000. It idles fine. Just not smooth and clean on take off.
So two things come to mind: I have the timing slightly off or I need a leaner setting if that is possible.
I'm guessing we're dealing with an R5 here . Sounds rich down low .
Can you identify which year R5 you have , as carb spec changed for last year in 72 .
A photo could help there too .
Can you list what jets are actually in your carb , which needle and slide cutaway too .
Have you checked float levels at all ?
Ok, is there a prize for guessing right?. Favorite trick was people would have both slides out then put them back in the oposite carb which turns them half a turn for the guide pin & puts the cutaway pointing forward, then becomes super rich like the chokes on untill you're prettymuch on full song. Assembled these new & worked on them right through plus i still miss the crashed one i bought cheap off the insurance. Hope this helps or i'll start again. Cheers. [choke not on].

If there was a prize you would be the big winner. That was exacetly what the problem was. It feels like a new bike. I had taken pictures of the throat and had them to confirm they were backwards. Runs great now. Once again this forum rocks! Thank you all.
