    lowell 1300 + 46 novis = jetting?

    just need a ball park idea on what jetting to run with a single pipe 1300. running 46mm novis with flame arresters on a pro-tec manifold, and moto tassarinni reed cages.

    I would start at 115 pilot 135 main, 2.0 N&S Black 80gram spring. 1-1/2 out on both screws, this might be fat as the 46mm will have a stronger signal. better to start fat and work your way down.

    I believe it, that is huge for a single pipe ported 1300. the jetting I gave you I feel will be fat but fatter is better while you are dialing it in. There is no history to go on for your peticular size carbs, so it may take one or two iterations to find the sweet spot. I am interested to see how this finishes up, we will add it to our database in the how to section.
