(2)450 DP's vs (2)750 DP's

Another little thing I’ve noticed. On some left hand turns it has a slight stumble as I accelerate out of the turn. My thought is that the jets are uncovered as the fuel is pushed away from the jets in the turn. My initial reaction was to put jet extensions and notched floats in the primary side. But then thought that would likely cause the same problem, just in right hand turns. So that leaves me a few options.

1) Leave it alone. Just be mindful of the possibility it could stumble.

2) I could up the fuel pressure a little and see how it responds.

3) Raise the float level. If I do this I’ll jack up the *** end till the bowls are level and adjust to mid sight glass. I realize this will likely require re-jetting and such.

Whatever I do, it won’t likely happen till next weekend as I have multiple club and family functions this weekend. That should give me plenty of time to over think the whole thing!
:lol:

I can’t remember if your carbs are inline or sideways.

If they are inline you may have enough fuel in the bowls that Turing one way will lift the float and shut off the fuel. But it would have to be an aggressive long turn for that.

The other thing I’ve seen is too much fuel in the bowl and when you turn it will dump fuel out one of the boosters.

At that point I lower the float level a touch and drop the fuel pressure.

I have learned that 5 PSI is plenty of fuel pressure. I’ve run some as low as 4 without issue.
